STONE: Good morning. My name is Robert Stone. I'm the acting director of MSHA's Office of Standards, Regulations, and Variances. On behalf of David Dye, the acting assistance secretary of labor for mine safety and health, I would like to welcome you to this public meeting today being held at the National Press Club in Washington, D.C.. The devastating loss of 12 miners at the Sago Mine explosion in West Virginia on January 2, 2006, and the two miners who did not escape successfully from the fire at Ericomo No. 1 Mine on January 19, 2006, clearly highlight the critical value of mine rescue operations following a serious mine accident. While MSHA is still investigating the cause or causes of these accidents and continuing a detailed evaluation of the emergency response, we are looking for ways to maximize mine rescue responses and improve opportunities for miners to survive after an accident occurs. Specialized equipment and technology are vital for effective, underground mine evacuation and rescue. The key components of communications and tracking of miners are the focus of today's meeting. On January 25, 2006, MSHA published a request for information in the Federal Register asking for comments, data, and other information on a variety of topics concerning underground mine rescue equipment and technology. Those topics included, among others, rapid deploy systems, breathing apparatus and self-contained self-rescuers, rescue chambers, communications, robotics, and thermal and infrared imagers. We have received over 35 comments to date. You can view these comments on our Web site. The purpose of this meeting is to complement the request for information by obtaining technical information from the knowledgeable mining community on technologies used for underground communications and tracking. This information will better enable us to evaluate which actions to take to most effectively improve mine evacuation and rescue capabilities consistent with our responsibilities under the Federal Mine Safety and Health Act of 1977. A notice of this public meeting was published in the Federal Register on February 23, 2006. We have copies of both the request for information and public meeting notices at the back registration table outside the room. The meeting format is as follows: Two of our panelists will give their presentations first. Next, those of you who have notified us in advance of your intent to speak will be allowed to make your presentations. Following these presentations, as time permits, others who requested an opportunity to speak will be allowed to do so. We invite all interested parties to present their information at this meeting, and if you are sitting in the audience now and wish to speak, please sign in at the registration table. We must vacate this room no later than 5 p.m. today. Subject to that time limit, we will remain in session today until everyone who desires to speak has had an opportunity to do so. If you are not speaking today, we would also like you to sign the attendance sheet so that we have an accurate attendance record of today's meeting. Following MSHA practice, formal rules of evidence will not apply at this meeting. The MSHA panel may ask questions of speakers. I may limit the questions of the panel for the sake of time. As is our usual practice and because of time constraints, we will not be accepting questions from the audience; however, if you do have questions, we would be happy to speak with you during the breaks. I request that members of the press refer any questions they might have to MSHA's press officers, Dirk Philpott, standing over there, who will be available in the morning, and Amy Lumiere, who will be available in the afternoon. They will be available directly outside this room and including during breaks and at the end of this meeting. We plan to have one ten-minute break in the morning and one in the afternoon, as well as a 30-minute break for lunch. If you have a PowerPoint presentation, please see Celina outside when the previous speaker is beginning to speak. When I call on you to speak, please come to the speaker's table and begin your presentation by identifying yourself and your affiliation for the record. Due to the large number of speakers that have already signed up and our 5 p.m. time constraint for the use of this room, we must strictly limit the amount of time for each presentation to 15 minutes. Fifteen minutes will be the total for any company, organization, or association. I will give a hand signal to indicate when five minutes remains and another one when one minute remains. When no time remains, I will state that the time is up. If you have a prepared statement or any supporting documents or presentational materials that you wish to submit for the record, please leave a copy with me today. We will accept written comments and information at this meeting from any interested party, including those who are not speaking. You can give written comments on this meeting to us today, or you can send them to MSHA's Office of Standards electronically, by facsimile, by regular mail, or hand delivery using the address information in the request for information. The post-meeting comment period on today's topics will end concurrently with the comment period stated in the request for information, March 27, 2006, and submissions must be received by that date. A verbatim transcript of this meeting will be made part of the record. It will be posted on MSHA's Web site, www.msha.gov, in a couple of days. If you would like a copy sooner, you can make your own arrangements with the court reporter. Let me also add that MSHA and the National Institute of Occupational Safety and Health will host a workshop on issues and concerns mentioned in the request for information. The focus of that workshop will be mine escape planning and emergency shelters in the mining industry. The workshop will be held on Tuesday, April 18, in Washington, D.C. We will be publishing a Federal Register notice soon that will formally announce this workshop. At this time, I would like to introduce others from MSHA on the panel with me today. On my left is Dave Chirdon, the chief of the Electrical Safety Division at the Approval and Certification Center. Mr. Chirdon is also attending as a presenter and panelist. His presentation will deal with emergency communication and tracking systems. On his left is Steve Luzik, the Technical Support Center chief at our Approval and Certification Center. Mr. Luzik is also attending as a presenter and panelist. His presentation will deal with the approval process. On my right is Bob Snashall from the solicitor's office. The first speaker on our panel today is Dave Chirdon, and he will be discussing MSHA's efforts to evaluate communications and tracking technologies. Dave? MR. CHIRDON: Thank you, Robert, and good morning, everybody. As Robert mentioned, my name is Dave Chirdon, and I'm the supervisor of the Electrical Safety Division, at MSHA's Approval and Certification Center. I have a brief presentation today to talk about what MSHA is doing to evaluate and advance the technology of mine communications and tracking. Before I get started, I did want to make a couple of points about underground communications. Underground communications and tracking, in and of itself is a challenge. The conditions that we're facing when we're evaluating communications and tracking for emergency usage are that you would have no power available at that time and also that any fire or explosion would have removed any cables or wire infrastructure that that communication system works with. So the challenge of providing communications from the surface to underground in an emergency is a serious one, but I think the evaluation that we're conducting has uncovered some technologies that can work under that situation, under those conditions. The activities that MSHA is currently undergoing to address the emergency communications and tracking issues: The first is we're investigating the Mine Site Technologies PED and Tracker systems. Since the incidents at Sago and Ericomo, there has been a lot of talk about the PED and tracker are approved by Mine Site Technologies. We wanted to take a look at these devices and see what the actual capabilities of those systems are. So we've been evaluating them by visiting mines, and I'll talk about that a little bit more. The other thing that MSHA has been doing is evaluating available new technology. Since the incidents, we have solicited proposals from the industry from manufacturers and from other organizations, and as of now, we have received about 80 proposals for different communications technology. We solicited these proposals over the MSHA Internet, and as of Friday, we've had 81 different proposals for emergency communications and tracking. We've been reviewing these proposals and have been arranging field testing of certain proposals, and I'll talk about that a little bit more as well. Now, as far as our investigation of the Mine Site PED and Tracker systems, so far, we've looked at the PED installations at Peabody's Air Quality and 20 Mile Mines. We've also looked at the installations at Blacksville and Robinson Run Mines. Now, those four installations that we investigated had the antenna for the system installed underground, so in those situations, that paging system could be used to communicate under normal conditions, but in the event of an explosion, you would have to assume that the antenna would probably be severed, and the communications would be lost. The one installation in the United States that does have that antenna installed on the surface is the BHP San Juan Mine in Farmington, New Mexico. We went out and looked at that installation. In that case, that system could continue to operate in the event of a fire or explosion because that antenna is located on the surface and would not be susceptible in a fire or explosion. Now, the tracker is another Mine Site Technologies, MSHA-approved device; however, it's not currently in us anywhere in the United States, so we sent a team of investigators over to Australia to investigate the performance of that Tracker system. They are probably in the air returning right now, so we're anxious to hear their results. Now, the preliminary findings on the pros and cons of the PED, and this is before we've actually compiled all of the results of our mine visits, the pros of the Mine Site Technologies PED are that it can send evacuation instructions to the miners in the early stages of a fire. In the case of situations where that antenna is installed underground, you would be able to send instructions to the miners before that antenna was damaged. Another advantage of the PED system is that it can be retrofitted for any of the existing cap lamps: Kohler, Northern Lights, and MSA. There is an MSHA-approved retrofit for all three of those cap lamps. Another possible with the PED is that if you have the underground antenna installation, that in the event of an emergency, and you lost that antenna, you could rapidly deploy a surface antenna to reestablish communications with that tracking system. Now, some of the cons we've seen with the PED system: Number one, as I mentioned, if you have that antenna installed underground, it could be compromised in the event of a fire or explosion. There are reports of some places in the mine where you can't receive the signal. They are referred to as "shadow zones." It can also cause interference problems with existing mine communications systems. The communications are limited to one way. The paging system can only provide a signal to the miner. There is no way the miner can confirm that he has received that message. That's a limitation of the PED system. Now, preliminarily, as far as the pros and cons of the Tracker system go, it is based on an antenna that is installed underground as well. It cannot use a surface antenna, so you would have to assume, in a fire or explosion, you would lose the connectivity of that system. In that case, the advantage of the system in the event of an emergency would be that it could at least provide you with the last known location of the people underground prior to losing the power and the signal. Some of the negatives, as I've mentioned, with that Tracker system are that it cannot provide a precise location of the people underground; it just can tell you what the last node that the miners passed was, so it couldn't tell you exactly where they are located, and it would become nonoperational in the event of a loss of power. Now, as far as these 80 proposals that we've received, we've evaluated all 80 of those proposals closely, and we selected several of those for further field testing just to get a cross-section of the capabilities and the different technology that's available right now. Now, what we were looking for when we selected those systems for tests were a number of things. Number one, we wanted to see what the system capabilities were. So we were looking for something that if it was a tracking system, could provide precise tracking, and if it was a communications system, we were looking for something that could provide two-way communications, something that you could talk back and forth on or provide a response to a received message. We were looking for something that could survive in an explosion. Because of that, we were looking for the wireless systems, systems that don't rely on some type of wire backbone. We were also looking at these 80 proposals and considering the state of development in which they were in. If it was just a concept, of course, we were not interested in field testing that at this point. So we were looking for things that were marketable as of now. And then the fourth thing we were looking at when evaluating these 80 proposals was something that could possibly comply with MSHA requirements. Now, we have some field testing scheduled on these systems that we've selected, and some of the things that we're going to be looking at when we go in to field test: Number one, we want to see how well the signal propagates. If it's based on these wireless nodes that are installed underground, we want to see what the range of each of these nodes is so you don't have to install one every 50 or 100 feet underground. We also want to look at how much overburden the systems can penetrate. If they are only good for up to 200 or 300 feet, then there is not going to be too many cases where they could be used underground. We want to see how well the systems can provide mine coverage. Are there a lot of dead zones underground, or can they cover all areas of the mine? We've also got to look at interference issues. You're going to be adding a lot of new communications waves and frequencies underground, so you've got to be careful about what type of interference they cause. One of the big concerns is will they interfere with any blasting operations? Then, as far as any tracking systems that we're looking at, we want to see how precisely they can track the individual. If they can only tell you within 1,000 feet of where the person is located, they are not as useful as if they could get it down to plus or minus several feet. So out of those systems that we've selected for testing at this time, these are the technologies that are represented. There are several wireless, node-based systems that use different IEEE protocols, the 80211 and the 80215. We're also looking at an ultra wide-band communications and tracking system that has great potential, and then we're looking at a number of these low frequency, narrow band, through-the-earth type of systems. That's the end of my presentation. I appreciate your attention. MR. STONE: Thank you, Dave. I should note that we have copies of Dave's presentation at the registration table, as well as copies of the presentation for the next speaker, who will be Steve Luzik. Steve will be discussing MSHA's approval process. Steve? MR. LUZIK: Thank you, Robert. I would like to take a few minutes this morning to go over our approval process for the benefit of the press in the room and some of our manufacturers who have not yet come through the MSHA approval process. Hopefully, we can get some answers on what the approval process is and what it is not. What does "approved" mean? An MSHA approval basically is an official notification that we have approved the device under consideration, and it has met our requirements with respect to the applicable part, and we have several parts that cover various classes of products and equipment, but for purposes of the discussion today, most of you will be interested in Part 23, which is the communication standard for telephones and signal devices. A favorable evaluation and approval certificate would indicate that with respect to this particular product, no probable explosion hazard would exist under normal operations when used in gassy and dusty atmospheres. This is an important bullet here, and if you get nothing else out of the presentation, remember this: In the case of communication equipment, we have no performance requirements. We're strictly looking at the product from the standpoint of being permissible in terms of not presenting an explosion hazard. And that's the reason we're all here today, and as Dave mentioned, we're looking at some communications systems so that we can get to the practical aspects of the systems, how well they will perform. Also, an approval is not an endorsement by our agency. The categories of underground equipment that we look at principally apply to what we call "in-by equipment." In-by equipment is equipment that is used in the areas of the mine that is mining coal where we have methane gas and fine dust being generated. The areas closer to the portal out by that area; those particular classes of equipment do not require our approval. There is a whole bunch of different types of products that we do approve, but we're going to confine ourselves, again, to the communications equipment, which consists of hand-held radios, mine pager phones, longwall face communications systems, leaky feeder communications systems, and systems of that nature. We also look at small instruments in terms of classes of equipment like noise meters, electrical measurement instruments, dust monitors, et cetera. The next couple of slides are going to talk about specific classes of equipment that we have approved at MSHA. Basically, there's four classes. We have mine pager phones, leaky feeder systems, hand-held portable radios, and other types of communication devices. We've approved five different types of mine pager phones, and you can see them on the slides. MSA has a system, Gal-tronics, Conspec, Pyatt-Boone, and Mine Safe Electronics. In terms of leaky feeders, and, again, for the benefit of those out there that might not be familiar with that term, leaky feeder systems are two-way-radio systems that feature a base station on the surface that communicates with individuals via underground radio units, such as walkie-talkie. To allow the RF to function underground, it's necessary to replace a standard surface antenna system with a cable network, and the cable is designed to leak signal, if you will, which allows radio frequency transmissions to leak both from the cable and also to the cable. These systems are generally used for both data and voice communications. So it requires an infrastructure and also a communication device. In most cases, it's a walkie-talkie. There are four leaky feeder systems that we've approved at this point in time: the Mine Radio systems, the Flexcom system; Mine Technologies has a system; DAC, and L Equip. At this point in time, we do not have any two-way communication devices that are being supported in underground mines. Motorola had two versions of a two-way Walkie-Talkie. They are no longer supporting those versions. They are no longer available. But the good news is we are in the process of evaluating a couple of two-radios for approval, and hopefully, in the very near future, we'll have at least one of those available as an option. Other types of communication devices that we've approved, and Dave has spoken about those a little bit right before me: the PED system, which has basically been approved on three manufacturers' cap lamps as a retrofit, and also the TRACKER IV TAG 4 system. Now, in the case of the TRACKER TAG IV system, we have approved the transmitting devices. You may have seen those in the news. They send a signal out to a beacon unit, which can register the presence of a miner passing that beacon. We have not approved the beacon. The beacon is used in out-by areas that do not require our approval. So that is another viable option, although it's not being used at this point in time in any of our mines. The approval process, in terms of Part 30, there are a couple of important things you need to know. Number one, the systems must be either explosion-proof or intrinsically safe. An intrinsically safe system, in and of itself, does not produce enough energy, either under normal or fault conditions, to ignite either methane gas or coal dust. If the system cannot meet that requirement, it can be placed in boxes, explosion-proof enclosures, which would prevent any ignition that might occur within that enclosure from propagating outside the enclosure. Normal signaling systems would fall under the IS, intrinsically safe, area of the approval standard. These systems must be supplied with back-up power supply in the event of a power outage, and, again, the entire system must be either IS or XP in the event of loss of ventilation to be used underground. The approval process consists of a couple of different steps. To begin the evaluation, an applicant would submit an approval letter, along with the appropriate drawings of specifications and any quality-assurance information. The Approval and Certification Center today is largely a paperless process. Manufacturers can submit their applications online. They can submit them via e-mail, and it's a very quick process. The information is dumped in specific folders that are assigned to our manufacturers, and the engineers can work back and forth in an electronic format, and it tremendously expedites the process. To begin the process, our engineer would take a look at the application and provide the applicant with a fee estimate. This would be a rough idea of what we think it would take to complete the investigation in terms of dollars. The manufacturer would get that, and if he comes back to us with an authorization, we would begin the investigation. Normally, we are conservative in these fee estimates, but if it gets to a point that there is a number of discrepancies, and we have to spend more time, we may need to go back to him at a point down the road and say, your fee estimate has been exceeded, and then he needs to give us authorization to add additional monies to the investigation so we can proceed. The investigators -- we have 11 or 12 electrical engineers and technicians that are assigned to these jobs. They review basically the product for compliance with the applicable standard. And, again, if necessary, discrepancy letters are sent. This isn't a process that can happen in a week or two, but if the product up front meets our requirements, generally we can get through the system in a couple of months, two to three months. If discrepancies are identified, and in some cases, it may require redesign, the process can go on for extended periods, and this happens on occasion, particularly when the manufacturer has not come through our system and may not be familiar with our requirements. I can say this up front. We are definitely committed to getting these new technology devices in underground mines, and Dave and I have made a decision. We have a policy that any applications for these systems will be put in a special queue and will be given priority considerations. The Part 23 approval system; there are some benefits we can take advantage of. Recently, about two years ago, we promulgated a Part 6 regulation that allows us to accept testing and evaluation results conducted by independent laboratories according to our approval standards. At this point in time, we have two or three recognized independent laboratories, so if somebody has a product that they want to have approved, they can go to somebody like UL, have them conduct the tests, submit the results to us, and that can be a time savings. If the device has been approved to UL or FM standard, many of the tests that that standard required are similar to the tests we would require, so we would have a time savings that can be realized there. Another part of the process requires us to inspect the prototype product according to the submitted documentation. I might throw in that we're currently looking at other standards out there in the world that could be equivalent to ours, either in their original form or with enhancements, as alternatives to our approval requirements. We're going to be publishing the results of an IEC evaluation that we did in the explosion-proof area, and we're also looking at the IECIS standards right now. So this could be somewhere down the line both a cost and time savings benefit. The quality-assurance requirements of the program: Basically, the approval holder is responsible for producing the products in accordance with the approved drawings and specs. For all of our products and equipment, we have a post-approval audit program, and another important point is that after the product is sold to the mining operator, it's the responsibility of that operator to maintain the approval in accordance with our approval. If anybody would like any specific information regarding our application requirements or our approval standards, they can visit this site, and we have our standard application procedures and also our test guidelines. I believe we're going to make this information available through Starpoint Presentations. MR. STONE: Yes. They are outside. MR. LUZIK: Very good. Well, that concludes my presentation. I thank you for your time. MR. STONE: Thank you, Steve. I will now call speakers from the audience. Please come to the speaker's table and begin by spelling your name and stating your affiliation. Remember that we must strictly limit presentations to 15 minutes. Our first speaker from the audience is Mike Koester. MR. KOESTER: Thank you. My name is Mike Koester, and the last name is spelled K-O-E-S-T-E-R. I'm the general manager of the Americas for Mine Site Technologies. I'm going to go through this presentation a little bit quicker than I was planning to because of the time constraints, but I think we should be able to get a pretty good point across. I would like to thank you for the opportunity to speak here today. Since late January, we've heard about a lot of the benefits and a lot of the limitations of the PED and Tracker system that are being used throughout the world, and what I want to do today is basically review those products and try and set the record straight in some aspects. These systems are being used around the world every day by thousands of miners. Our mission is enhancing safety and production, and, again, I'm going to skip through this one just in the interest of time. Our product that we manufacture is the PED, which is a personal emergency device. It's a text-messaging system to every miner underground. We also manufacture a Tracker system; an ICCL, which is integrated camp lamp, which includes the PED and tracker tags. We do an ImPact, which is a wireless technology. You saw some of the references to applications for approval. That's basically the 80211 protocol. The VDV is a leaky feeder radio system. It does have limitations. It's a two-way, voice radio system, but it's basically line of sight. You can push it a little bit further than that, but there are limitations to it. We have over 250 clients in five continents, and as you can see up here, I've got the PED installations in Canada. We've got 20 PED installations in the U.S., 72 PED systems in Australia. And some of these systems you note here are 40 blast PED systems where we can actually offer a product that initiates shots. Hard rock miners set off their blasts with the PED system as well; it's that reliable. These are some of our valued customers. We are a true global player. We have a lot of installations in hard rock mines as well as coal. The person emergency device, the PED unit. Following a -- explosion in 1986 in Australia, there were 12 fatalities, and basically the underground infrastructure was destroyed, pretty much what Dave alluded to. The development started in 1987, and what they did is they reviewed a lot of research that was done by the Bureau of Mines and other institutions around the world. We also looking at an event that happened at the Sunshine Mine in Kellogg, Idaho, in May of '72, when there were 91 miners killed because of a fire. Basically, there was smoke smelled at around 11:30, and at 1:30 they were still trying to notify miners to get out of the mine. The system was arranged to contact underground miners with a surface antenna, and we felt that text had more usefulness than verbiage or voice communication just because of the chaos, the noise, et cetera, that takes place under ground. The system became commercially available in 1990, and MSHA approved it in 1991. Just to quote there at the bottom, it's kind of difficult to see, but basically what the U.S. Department of Labor and Mine Safety and Health Administration has said is that time is never your friend in an emergency. The personal emergency device is a ultra-low-frequency, mine-wide, text-messaging system. It is a mine-wide warning system, and, again, it's not limited to line of sight. It's an everyday communication tool, and you can send text messages. It can be remote initiation of blasting from the surface. Productivity: People contact personnel wherever they are in the mine. Efficiency through remote control. We can turn on fans, pumps, et cetera, with it as well. This is kind of the evolution of the system. You can see, in 1989, was the first prototype, and as we progressed through the various stages, this product right here is available now for the lead-acid battery, and this is the ICCL. It's a lithium-ion battery. That unit contains a PED and a tracker tag. In March of this year, we're going to apply for additional funding to finish research that we've done on a two-way communications system. We're pretty far along with it, and we hope to get that done probably late 2007, maybe 2008. This is a schematic of the system. The PED system basically detects messages that are sent off of a PC into a modulator, which then transmits that information to a transmitter, which either can be located on the surface or underground. You have a loop antenna. It's strictly just a loop antenna. It's a number six wire that's laid out into a loop. The area of coverage depends on the size of the loop. I will state here that this system generates a continuous, ultra-low frequency, and you've heard people say that it causes interference with some other systems, and it will if those other systems are not grounded, or they are not shielded properly. With some of our earlier installations, we found this out, and we've actually helped people work through getting the noise out of their systems. The system is designed for self-diagnostics, ground fault, open antenna, and lightning strikes, et cetera. The PED receivers: You have an ICCL, and you have an auto PED. You've heard about shadow zones. Well, with an auto PED, if people are traveling in a vehicle, it's basically an external antenna that fits on a vehicle, and that will allow the message to be received. Then we have control PEDs and blast PEDs. This is what the unit looks like on a lead-acid battery. You have a liquid crystal display up to 32 characters. You can recall the last two messages being sent. I want to get into this a little bit more, spend a little more time on this. This is communication coverage. This is a mine layout of a longwall coal mine. You see the loop antenna here, a loop antenna there, and a loop antenna there. Well, if you look at the coverage that's provided, phones basically give you 5 percent. If you go to leaky feeder, you can maybe get 20 percent. Now, you can take the leaky feeder and extend it into more entries, but as Dave said earlier, in the event of a catastrophic explosion, all of this infrastructure is going to be taken out. Now, this is what the PED coverage looks like based off those antennas, and basically that's given us 98 percent. We've got a little open area right up there that we're not getting. All we have to do is extend that antenna there, and we'll get that area covered as well. This is the Wallarh Colliery in Australia. This is under a very populated and very heavy, hilly area. It has a surface antenna, and it is protected from blasts and a fire. It's a 12,000- and an 8,000-foot surface antenna, and it's powered by one transmitter, and they get 100-percent coverage. This is Kanowha Belle. This is a hard rock mine, and you can see this antenna goes down. It's through a vertical and horizontal configuration. It's an underground antenna, and it covers the entire depth of that mine. This is the Moranbah North Coal Mine in Australia. Again, all we have to do to get broader coverage is just to increase the loop on the antenna. This is a 33,000-foot surface antenna. Surface antennas can be used in an emergency. Like Dave said, if all of this infrastructure underground is taken out, it just takes a matter of minutes to lay out another loop antenna on the surface, and you can start to retransmit again. These are some of the installations, and I'm not going to go into all of them, but these are just some of the installations we've got: Cook Colliery in Australia, 1991; it's a surface antenna. They have 45 pagers. They send 10 to 20 messages per shift. It's just a regular communication routine in their production day. You can see Crimum Mine, 280 receivers, 40 to 60 messages a day. Again, Andalex out in Utah, Genwal in Utah. West Walls in is Australia. You can see the number of pagers, the receivers that are used. Here we have Co-op, Dougout, BHP in the U.S., Air Quality, Laurel Mountain. I would like to comment here that we're getting anywhere from 70-to-100-percent coverage on these installations. Each individual one is really dependent on the antenna configuration. In the U.S., we have a total of 18 installations. The first one was installed in 1996. Again, the shadow zones and so forth is antenna-dependent. Worldwide, we've got 140 systems, and that's over 10,000 receivers very day being used. This is the TRACKER tagging system. Basically, it allows you to know who is in and who is out of the mine, and you can identify location of people and equipment within clearly defined zones. The benefits: safety management, people management, and equipment and asset management. It was approved by MSHA in 2000. This is a reader/beacon and a tag, which I'm sure you've seen in the press. The beacon will read up to 150 feet in a radius, or you can directional it out to about 200 feet. It reads this tag, which is continuously generating an RFID signal. This would be a typical TRACKER beacon layout of a coal mine. You can see the red boxes. That's where the beacons would be, so as people progressed into that mine, you would know their approximate location, that they were between that beacon and that beacon, for example. In the event of an emergency, if the power was still on, and the infrastructure wasn't taken out, you would be able monitor their movements out of the mine. This is the Lindstrom Mine in Australia. They have over 700 tags and 45 beacons in use. They tag equipment, and they tag people. You can see the green zones. The green zones, they use for blasting. If everyone is back in a green zone, and there are no people in the red zones, then they go ahead and set off their charges. You can click on a beacon, pull up information such as who the person is, where his locations were, what time he passed those locations. These are zone displays you can use to limit traffic flow, stop signs, et cetera. And, again, just to summarize the tagging system, it streamlines access control in the ventilation districts during an emergency. Withdrawal of personnel can be monitored. When you combine that with the use of PED, you can actually direct their egress from the mine. It has the potential to extend into a tagging system that uses proximity detection, which we will be doing here very shortly. And with that, I thank you very much for your time. MR. STONE: Thank you. MR. LUZIK: I have one question, Mike. What would be your expectation of the practical limits, depth-wise, for a surface antenna installation? MR. KOESTER: Depending on the strata, we get anywhere from 3,000 to 4,000 feet vertical. Now, aquifers will impact that to some extent, but we can say 3,000 to 4,000 feet. MR. STONE: Thank you very much. Our next speaker from the audience is Dave Beerbower. Would you please come forward? MR. BEERBOWER: I would like to thank the panel for the opportunity to come and speak from an operator's standpoint. You've heard the manufacturers' standpoint. I would like to add our input because we do have three of these systems installed worldwide. Peabody Energy is very committed to improving communications at all of our operations. We think that the opportunities are there, and we want to move forward, and we want to be sure that what we're doing is the right thing to do. We originally started with the PED systems in Australia at a mine that we have actually purchased from another operator. The same thing is true at 20 Mile. We have installed our own system at Air Quality. The PED devices are reliable communications systems, and I say that with this qualification. They are reliable, as Mike said, in most cases. They can deliver one-way text messages to most miners in almost every location of an underground coal mine, That, however, differs greatly from what has been proposed as legislation that says that it must be able to communicate with all miners in every location underground. If antennas are located on the surface, which we do have one of those in Australia, the signal can be more reliable and can reach more remote areas of the mine. There are some setbacks to that type of a system, however. In Australia, it works well because our mine is rather remotely located, and we actually just lay the antenna on the ground above the mine because we own the surface. In our mine in Colorado and the other one in Indiana, that is not the case, and particularly because of, in the 20 Mile case, because of the topography in which we find ourselves, it makes it very, very difficult to locate a surface antenna there as well as property issues. And in the Air Quality Mine, because of the surface areas being farm land and private property, again, we have found that it makes more sense for us here in the United States to place those antennas underground. Obviously, when you place the antennas underground, that introduces -- as has been said, the mine environment then takes its toll in the case of an emergency. In fact, the system that we have at 20 Mile right now is the same system that was used at Willow Creek, and a lot has been said about Willow Creek receiving those signals to evacuate the mine. What hasn't been said is that within two minutes after the signal being sent, the antenna was burned in two, and the system became inoperable. So there are limitations, and I think we need to recognize those limitations when we're talking about regulations and laws that operators must comply with if they are going to be able to mine coal in this country. As I said, we have a system at 20 Mile and one at Air Quality in this country. In both instances, those antennas are underground. We place PED devices on our front-line supervisors, all out-by workers and floaters that travel from section to section, such as fire bosses, pumpers, and mechanics. It was determined that this setup provided adequate coverage to all areas in which mines would likely be working. The antennas are underground, and, quite honestly, we have experienced shadow areas in both of those locations, as well as the one in Australia. So even with surface antennas, there are instances where we have found shadow areas. The other difficulty that we are finding is that in some of these areas the antennas cannot be placed in the same entry, and so where there would only be one entry available, it makes it nearly impossible to extend the antenna into further areas of the mine. These shadow areas that we have experienced occur mainly in bleeder and in remote areas such as tailgates of longwalls. Again, signal propagation seems to vary widely, depending on the coal seam itself and, in many cases, on the types of roof supports being used at the mine. Both of our U.S. locations are using wire mesh for the immediate roof control, and that has definitely had a deleterious effect on the ability of that signal to propagate longer distances. We are in the process of looking at why that occurs. We're not sure, and I think there is a lot of research that needs to go on with these systems, and even looking perhaps in West Virginia, where we're looking to put some more of these devices in, we don't know if we are able to put a surface antenna in. We don't know the effect of overmining, and as you are aware, in West Virginia, we have, in many cases, seven or eight seams that have been mined out above our operations. We think that may have some impact on the ability to propagate a signal from the surface to our mines. We also have looked at, as Mike had mentioned when he talked about the new technology that's out there, the ICCL device. That has great promise, and that's something that we are very interested in looking into. It's in the approval process in Australia right now, and as you know, it is a lithium-ion battery with the tracker and the PED device included in one unit. This is, I think, a very positive step in the right direction because, as you know, the PED on the lead-acid battery is a very heavy device, and it looks like this newer device has some real promise for us, and we're looking to the agency that as soon as the Australians approve this device, we would like to see it brought to this country and quickly approved for use here. I think it would help us, too, as we try to gain the acceptance of the miners of these newer devices, if we can put something on their belt that is lighter and provides all of the services that we need it to. I think we'll have a better opportunity to make it acceptable to everybody. One thing that has not been talked about much in these regulations, because of the limitations that are out there with these communications devices, we feel that it's necessary for the discussion to begin on what happens if a miner goes into an area in which he does not have communications, if he goes into a shadow area that we've experienced. Again, if the system goes down, as most mechanical systems will, what are the procedures that a mine operator must take while that system is down and being repaired? This happens from time to time, and there has to be an acceptable alternative short of evacuating the mine if that does occur. I want to switch now and start talking about tracking systems. Again, a lot has been said about the hardware that's involved in that system. There is not a system in the U.S., and I think there is good reason for that. Quite honestly, that system was developed in Australia. The Australian mining system, and, again, I'm speaking from experience at our underground mine there, the reason that system was developed was mainly for tracking mobile equipment and the numbers of manpower that enter sections. There are limitations as to how many miners can be in an active section there, as well as the number of diesel-powered vehicles. So for those reasons, it had great advantage for an operator to be able to tell how many units were on the section. Right now, it's being done with just a regular tag board, like you would say a check-in and check-out board at a U.S. mine, and each device, as they approach this section, would put their tag on a tab board. What this tracking technology will do is to do that automatically, and it would tell the operator of any piece of equipment, stop, you can't go in this until another piece of equipment comes out. The reason that was developed was for good reason there, and that has not been the case here in the U.S., so I think that's one of the reasons it has not been put in here. Again, I think we find in the regulatory language there are great problems with what has been proposed, and I think there is a misunderstanding amongst those who are writing these regulations as to what the capabilities of the Tracker system are. Most of the regulations that are coming out of the states and that we've seen proposed in the federal realm have said that it must be able to provide real-time tracking for all employees while they are underground. Quite honestly, and I think Mine Site Technologies would admit, that is not possible. One thing that Mike did not say -- he did talk about the range of these beacons as being about 50 meters, and that's about right -- what the problem is it has to be line of sight. Most of the Australian locations are two entries, and one of those is a belt going into the development areas, and so everyone travels in the same entry. That's fine when these systems work line of sight. In the U.S. system, however, if, for instance, a miner, in an emergency, decided to go out the intake escape way or out the return, the beacon would not pick up the transponder's signal, and that would make it very difficult to tell where people were. That puts mine rescue teams at risk when they may not need to be placed in that situation. In closing, I would ask that as we look at communications, we not forget the mine rescue teams. They are an absolutely fantastic group of miners who have really put their lives at stake for their fellow miners, and we need to work on communications improvements for them also. The state of communications and tracking devices, though fairly reliable, is a far cry from what lawmakers have envisioned them to be. There is nothing that will meet the current language that has been proposed. If the agencies want to mandate the PED, communications, and tracking systems, they should develop rules that are consistent with these known limitations. NIOSH should also continue to explore promising technologies, along with the AC&C, that will someday allow for two-way communications and tracking for all miners. The system infrastructure must be unaffected by the mine environment, and both of these are worthy goals, but they are not currently available. Peabody stands as a willing partner with NIOSH, MSHA, and other interested parties to begin the search for a reliable system that will someday meet these ultimate goals. Thank you. MR. STONE: Thank you. Dave, could I get you to spell your name for the record? MR. BEERBOWER: I'm sorry. Beerbower, B-E-E-R-B-O-W-E-R. MR. STONE: Thank you. MR. CHIRDON: Dave, can you tell me why you guys chose not to put your antennas underground at Air Quality and 20 Mile for the PED system? MR. BEERBOWER: They are underground. MR. CHIRDON: I mean, on the surface. MR. BEERBOWER: The topography in Colorado is tremendously difficult. It would make that nearly impossible, with cliffs and very high and steep slopes in the Colorado region, plus we don't own the surface area either. In Air Quality, it's a surface ownership issue, as well as valuable farm land and homes above our mine. MR. STONE: Thank you very much. Our next speaker is Shawn Stewart. Would you please come to the speaker's table and begin by spelling your name and stating your affiliation? Thank you. MR. STEWART: Good morning, everyone. My name is Shawn Stewart with X Systems, S-H-A-W-N S-T-E-W-A-R-T. We are a technology company out of Atlanta, Georgia, and a Cisco partner. I'll bring this up in just a moment for you. Why are we here this morning? We're here to save lives. How do we save lives and reduce time in search and rescue? How can we reduce time in search and rescue? By eliminating the search. How do we eliminate the search? We know where everyone is at all times. Now, I've heard other gentlemen come and speak about the inability of this to happen, technology-wise. We come in from a corporate environment, myself, as a Cisco partner, Cisco Systems. We have a bit of a tie to the mine environment. My father, who is with me today, Jim Stewart, is a 25-year veteran of the Kentucky coal mines, 15 years as a foreman. We take this technology a little bit personally because we understand that with a little bit of work, we can track everyone. What we do, we build wireless networks. That is what we do. Why do you care about wireless networks? The main equipment of a wireless network can be placed in an MSHA-approved container that is, as we call it, explosion-proof and meshed throughout the internal sections of a coal mine. This creates a wireless network inside the mine. Now, I believe I heard the gentleman from Peabody explaining problems with -- I believe that's called multipath distortion with the wire meshing units. We do understand the way these wireless technologies function. What we do is increase the number of actual wireless points to get around this multipath distortion. With the wireless network, I know where this is at all times. What is this? This is a wireless, RFID tag that chirps, indicating its location at all times. This can also be placed inside of a small, MSHA-approved container that can be worn on the miner's person. This device itself is not MSHA approved, but I do believe there are some companies working on right now getting these devices approved, but at the time, we can put them in containers. Therefore, I know where the miners are at all times. In the event of an accident, a rock fall, fire, explosion, or flood, we can reduce search and rescue to just rescue because we know where the miners are at all times underground, and that saves lives. Again, coming from a corporate environment, these are the types of technologies that are currently in use. This is merely a screen shot of some of the technology. Like I said, we build wireless networks. This network gives us a secure Web portal that can be viewed from anywhere in the world. This is a representation of what is shown. The layout is a standard, underground mine diagram. Using any Web browser, we know who or what we're looking at with a single click of the mouse. Locations of miners in this example are shown in green. Locations of assets, such as the longwall miner and roof build machine, are shown in blue. Now, I know some of you are going to look at this and go, wait a minute. There is a miner and a longwall in the same cut. We understand that. That normally doesn't happen. This is for presentation purposes only. The network provides secure, two-way communications underground. The purple square indicates a secure, two-way communication device, in this instance, a wireless phone. Now, right now, as far as I know, there are no MSHA-approved wireless phones. We are working on a small container that has a plastic front cover to allow the voice to pass through and for button use. As of right now, there is no MSHA-approved container for that, but we are working on that. Another critical function the network can provide is two-way video, so in the event of an emergency, we can see what's going on. The network can potentially provide telemetry information, such as methane levels, temperature, heart rate, equipment maintenance, and lock-out and tag-out procedures. If levels reach certain thresholds, this information can trigger an electronic notification or alarm. Many equipment manufacturers, such as Joy, have included a standard network connection providing real-time status of the equipment. That connection connects to our wireless network as well. The network can send electronic notification if it detects activity that's suspicious or unsafe. Certain areas of the mine, particularly near moving equipment or high voltage, can be deadly. Notifications or alarms can be sent if a nonqualified miner enters an unsafe area. Most importantly, we know where all miners are at all times in the mine. In the event of a catastrophe, we minimally know where the miners were at the moment of the event. However, we do have certain built-in redundancies in our network. Our wireless network works on what is called a "mesh network." This is a relatively new technology in the 802.11 system through AB&C Technologies from Cisco Systems that we are currently using in several, several places, especially in gaseous areas such as radioactive areas. I think Pracsare is using this in some of their gaseous areas as well. Cisco stands behind us in everything we do. We are a partner. We are Cisco wireless specialists. In the event of a catastrophe, even if we had a major rock fall on a main line coming in, we have a built-in redundancy of a secondary line that runs either through the intake or the return. This is a fiber-optic cable. As you can see, this is actually the fiber optics. This is MSHA- approved, fiber-optic cabling. The cost is very inexpensive in relation to even the high-voltage cabling that runs already through the mine. Two lines of this, one through the main line, possibly even one in both the return and the intake, will guarantee that the network stays up even in the event of a major catastrophe. Beyond that, even if all lines were cut, a new wireless system could be put in place in front of the mine rescue team to guarantee a reconnection with the network. In the event of a catastrophe, the foreman is required to contact MSHA, the union, and bring in a mine rescue team. With the Mine Rescue Command Center, they have full access to our network that's in place, and with the wireless network in place, they have secure, two-way communications while on site using standard wireless phones outside and inside. There is no need for a rapid deployment system; it's already in place. Since the network has its built-in redundancies, we still have the secure Web portal that can be viewed from anywhere in the world. We still have secure, two-way communications with the men underground. We still have our telemetry information, and we still know where every miner is at all times. So we strive to eliminate the search from search and rescue. It may take a little time to verify that all parts and pieces of this solution are completely approved, but we can put this system in place and save lives. Any questions? MR. CHIRDON: Have you done any field testing of your system? MR. STEWART: We have a marble mine in Georgia. I understand that marble is different than coal. They have allowed us to come in and do various, various testing. What we found in the solid rock, because they, too, work in the rim-and-pillar system, that we, too, even in a marble mine, get full coverage, 100 percent, even in their shadow areas. The equipment that we use is industrial strength used in typically warehousing industries. The system itself was actually created to track important assets in hospitals, like babies. So we keep full test on this. In the marble mine, we can actually track any asset, any miner. MR. LUZIK: Do you have test results you can make available to us regarding that experience? MR. STEWART: We can. That should be available by the end of the month in report form. MR. STONE: Thank you very much. MR. STEWART: Thank you. MR. STONE: Our next speaker is Martin Fishwick. Could you please come to the speaker's table? (Pause.) MR. STONE: Could you begin by spelling your name and stating your affiliation? MR. WILSON: My name is Brian Wilson. I'm the CEO of MineCom - Australia. Martin Fishwick is one of my employees. He was communicating with the lady over here from Australia for me. So it's Brian, B-R-I-A-N, Wilson, W-I-L-S-O-N. As I said, it's MineCom - Australia. Okay. Thank you for the opportunity of talking with you today on wireless communications and tracking in a mining environment. A brief introduction to MineCom. We're an 9001-2000 company through SGS. We have offices and factories in Australia and South Africa. We have distributors located around the world. Here in the U.S.A., we're represented by Pyatt-Boone Electronics, who are a world-renowned company in the field of mining and gas detection and conveyor belt equipment. Okay. We have been manufacturing and designing communications products for the mining industry for the last 19 years, based in Australia. We started off in Tasmania, the island there on the bottom where the Tasi Devil comes from, and we're spread out from there to everywhere, to Russia, China, Sweden, South Africa, and so on. We have leaky feeder backbones, wireless automation systems, personnel and vehicle tracking systems, block light systems, heavy-duty radios, collision-avoidance, and traffic-management systems. Okay. Redundant communications to protect the mine's assets. An asset is a resource having an economic value that a corporation controls with the expectation that it will provide a future benefit. People are assets, and, therefore, they must be protected so they can continue to provide a future benefit to the corporation they work for. Redundancy: Duplication or repetition of elements in electronic equipment to provide alternative functional channels in the case of failure, or a system design that duplicates components to provide alternatives in case a component fails. Okay. People are putting out, say, a tender. Monk's Mining Corporation requires a fully redundant communication system for its Monks No. 1 underground coal mine. The communication system must be fully redundant, i.e., continue to work, operate under all conditions, including explosion, rock fall, and cable break. Okay. We first introduced what we call a redundant system, which was a ring feeder, some five years ago, which supplied a continuous ring of leaky feeder in a mine. If the cable was damaged, you could still communicate on both sides of the leaky feeder. It's similar to a fiber-optic, self-healing ring. If you break the fiber-optic cable, the signals find another way to get around to the other side of the break and get there one way or another. Okay. In 2005, MineCom introduced SMARTReverse, which was the first fully redundant, leaky feeder-based communication system. It was originally designed for mainline railways in long tunnels where, if a cable was damaged, the train could still be communicated with on both sides of the cable break. Okay. The problem being in mines is that for SMARTReverse to work and be fully redundant, there must be two egress points, two inputs and exits from the mine, for it to work efficiently. In hard rock mines, that's normally a standard. In coal mines, it doesn't always happen. Okay. A secondary egress can be a return air shaft, a skip, or a cage shaft, escape way shaft, vehicle decline, or drill a bore hole, a four-inch bore hole down. It only has to carry a couple of cables or even one cable. So in a mine like this, SMARTReverse, when it worked, this was only one egress point. In this mine, yes, it would work because there's two inputs to the mine or two escape ways. If one is blocked, you can get out the other, and we can get the cable out. The gentleman from Peabody was saying that the difficulty was they didn't own the surface, but on the surface, the return path can be wireless, fiber, or copper pairs. Okay. Again, here SMARTReverse would work because there are two egress points. In a coal mine situation, in this mine, no, unless you went down one tunnel, turned around, and came back the other. Again, one egress point. Drill a bore hole down, a four-inch bore hole, down from the leaky feeder cable up. Run the leaky feeder back along the surface, and you have a fully redundant, leaky feeder system. Okay. Alternatively, you can use RF-to-fiber devices and come out of RF into fiber, up the fiber-optic cable, and returning on the surface through a trench back to the start point at the head end. Option 2 is you could go up two shafts, run it up the second shaft back to the surface, and then either wireless, cable, coax, fiber, copper wires. Again, you can run the leaky feeder up the shaft and back on fiber. Okay. SMARTReverse, as I said, the return path can be leaky feeder cable, fiber-optic cable, a wireless link, or even good, old-faithful, copper pairs. In some mines here, and this is relays -- they are not interested in anything else, but copper pairs still stay in a lot of mines. Okay. The MineCom SMARTReverse is a reversible, bidirectional amplifier using custom-built, helical filters to provide selectivity and act as duplexers to provide sufficient isolation between the uplink and the downlink paths. Should the cable be damaged, single-pole, double-throw, RF switches with high isolation characteristics electrically reverse the normal uplink and downlink RF paths to the amplifier. SMARTReverse is a full-tolerant, leaky feeder system that can operate in a harsh mining environment and provide reliable communications on both sides of a damaged cable. The direction of the bidirectional amplifier is controlled by the presence or the absence of a control tone put down the leaky feeder. In other words, if the control tone is transmitted downlink at a VHF frequency, it's amplified and boosted all the way along the cable through each individual amplifier. SMARTReverse amplifiers are also equipped with what we call "drive-by diagnostics" in the form of ultraviolet LEDs indicating the condition of the amplifier to staff as they pass so the staff can drive past and see comfort green LEDs and know that the signal level is okay, the voltage level is okay, and the current drain is okay. We also have an optional, PC-based, diagnostic system that will then display all of that information and the ID of the amplifier back on the surface on a laptop PC or a fixed PC. Windows-based software allows you to read it without great difficulty. Okay. SMARTReverse is available not in one band but five bands virtually. We have it in VHF, UHF, wide band, where you have 10 megs bandwidth up and down. We have it in narrow band, which was designed for Europe to work on existing trunking channels in Europe, and that only has one and a half megs bandwidth up and down, but it has 10 megs separation to suit the trunking and the digital tetra and tetra and tetrapol systems. We also have it available in 800 and 900 megahertz, and there is another one which is 2.4 gig. So by virtue of the SMARTReverse amplifier, the two upper amplifiers within the amplifier box will reverse. The other amplifier provides video and control tone signals. It does not reverse. So in a normal condition, the amplifiers are in one direction. Okay. As you can see here, in normal condition, in the case of an explosion, these two amplifiers will reverse. They reverse in the opposite direction, and the signal will get back. When the cable is repaired, they return to normal. The other thing is that you run a leaky feeder cable, and it's not being used to its full extent. A leaky feeder can carry more than voice, data, and video. You can cut the leaky feeder cable and put a box in there that will give you telemetry with analog and digital inputs and outputs. If there was an explosion, and the cable breaks, the data is still going to get back to the surface. You can cut the cable and put a camera in it. If there is an explosion, and the cable is broken, the video images on the down side, which is the side that you want to get the information from, can still get back to the surface. Tracking. You can cut the cable and put a tracking unit in, and the tracking will work on both sides of the cable break. You can put the tracking units every 350, 500 meters, 50 meters, if you want to pay for it. Okay. You can also have automation, control of pagers, skips, and, again, break the cable, and the system will work on both sides. We also have tracking, passive, and active systems, passive personal tagging, active RFID. We now put the tags in the actual cap light rather than the cap battery. In the battery, they are shielded by the vehicle. In the cap light, they are going out through glass, so they radiate out further, and it uses one of the wires as an antenna. LAMPS is IS approved to IUC standards. It was developed with the CSRO in Australia. Again, it's an IS-approved tracking system. We also have shock-proof and weather-proof, water-proof radios for vehicles. We also have wall-mounted, safety radios that you can mount on the wall, and they are powered by the leaky feeder cable. So you run the leaky feeder cable into the radio box and back out. It gets its power from the leaky feeder cable. In case there is a power failure, there is backup on the leaky feeder cable. Last, to conclude, MineCom provides a written guarantee with every system that's installed to our specifications. We guarantee communications wherever you run that leaky feeder. Finished. End of subject. Thank you. MR. STONE: Thank you, Brian. MR. CHIRDON: Mr. Wilson, apparently, you have plans to get into the U.S. market. What are your plans for getting MSHA approval of your device? MR. WILSON: That's what we're doing here at the moment. I was here two weeks ago to speak in Virginia, and we heard of this one, so I came back over to speak again and have it submitted through Pyatt-Boone, our agents. MR. CHIRDON: Thank you. MR. LUZIK: I have a question. With regard to your redundant system, if we had a particular incident where multiple breaks occurred -- let's say we had a long entry, and multiple breaks occurred, maybe one five or 6,000 feet in-by and then out-by a couple of thousand feet, so we have two distinct breaks in the cable. Would your system be able to communicate in that distance? MR. WILSON: Unless we have another entry/exit point. Again, it comes down to being able to get into the system. You have one entry/exit to the mine. Of course, the people can't get out on the down side. There is no escape way. There's no escape ladders, where in many hard rock mines and some coal mines in Australia, they have got access ways to get out, and, yes, then we can take off points at various locations. We do that in that case using RF to fiber where the device picks up the RF signals, converts them, and modulates them along a fiber-optic cable back to the surface. The more take-off points you can put in, the safer the system, but you need more than one exit. MR. LUZIK: Thank you. MR. STONE: Thank you very much. Our next speaker is Mark Rose. Please come up. I'll remind the audience, if you're going up to speak, and you have a PowerPoint presentation, please see our staff when the previous speaker is coming up. Thank you. MR. ROSE: Good morning. While we're getting ready here technically, I would like to introduce myself. My name is Mark Rose. I have a little company out in the West called Tunnel Radio of America. I've come here today not so much as a salesman but as a wireless professional. I've worked in wireless directly for 30 years and directly in underground mine wireless for 18 years. We've put in over a thousand miles of systems in the United States and a number of other countries. Education with the Northrop Institute of Technology and East L.A. Trade Technical College. It looks like we're booting up here, so it will be a little bit more time before we get into the electronic portion of the presentation. Like I said, I'm really here more as an industry professional that is concerned. I'm very happy that the federal government and the State of West Virginia have kicked over this bucket concerning mine underground wireless. It's been a passion of mine since the first mine I ever attempted to do this in. Like I said, we do have a little bit of experience in this area. The largest system we put in was 70 miles of underground workings at Home State that worked flawlessly. That mine is closed at this time. We have a few other ones out in the West. I have an FCC license to maintain and build this stuff, a number of others from the FAA. So let's take a look at the presentation here, and we'll move right along, hopefully. Some pictures from our group when we've been in the field at various times, and the question is, why do we do this stuff? We do it for them. No more needs to be said. We primarily put in two-way wireless systems. We try to get the people connected. It makes a huge difference in an underground operation to get people talking and connected. It completely changes the attitude of the miners in the mine and completely changes how a mine operates once they get a good, wireless, two-way system up and running. I list some advanced requirements here that all of my colleagues that are here that are vendors go for. We like to have multiple channels. We like to have wireless data. We like enhanced range. Coming up with a system in a technology that's got a predictable coverage in a facility when you get in and what you have advertised are sometimes difficult to do. So when you do, to maintain your integrity, you want to be able to develop and install systems that are reliable, and their performance is repeatable every time you put them in. A little bit on tracking, we'll get into, and then some of the emergency operational features. I'll touch a little bit on protocol and Ethernet-compatible systems, too, in this presentation. I apologize for the logo. I'm trying to keep this a generic presentation, but the pictures are pretty good there. Actually, that picture of the loader is one of my best ones, and that's when the flash didn't go off in my camera. A typical distributed antenna system, as defined by the FCC, is a network connected to a base station radio with an antenna portion, which would be kind of lined out with these black lines here going down into this hypothetical facility. We've got a lot of ramps out in the West. We've got to go deep for a lot of our ore bodies, and we use a ramp to do that. We also have shafts. We've got some of the deepest ones in the world. At Home State, we were down about 8,000 feet when we were all finished there. It's a very dangerous facility to work in. You need good communications to keep your people in good stead, and there are a lot of stories about that that we've seen over the years. We specialize up in the upper band and have patents up in that band, which is 300 and 900 megs for a reason, and we'll talk about that. We go for coverage. You know, when you put a two-way system in, you want distributed wireless coverage. That's the main purpose of the system, to get the people connected. So we've got a couple of things you do with that. You've got wireless data possibilities with coverage like that and tracking. We test our systems. Showing the two types of technologies here, VHF versus UHF, a little diagram. Measurements taken off of these cables are done scientifically. The term is "coupling loss," and at 20 feet, typically for these cables, the coupling loss is 65 dB where 30 dB is 1,000 times loss, so 65 is way down there. Distributed antennas at UHF; we're around 40 dB, so we're seeing nearly a 30 dB difference, which is a thousand times more effective power in these systems when you're running in these upper bands in mines. So what you end up with is you've got greater range, you get obstacle passage, and you get a lot of reflected energy off the bounces going into these things called stokes and entries and cross-cuts, all of these terms that people are trying to grasp that those of us who work in the industry pick up over the years that mines know and work with every day. All right. There is a picture of Monica down there in the right-hand corner. Now she is mine manager at LKB Monbay. I worked with her putting in wireless data on their loaders. They have got wireless loaders running without men tracking and doing production monitoring. This PowerPoint didn't come out very good when I tried to transfer it. Sorry about that. Now, we'll get into some of the ancillary devices you can install on these wireless, distributed antenna networks. All right? Wi-PAD is a wireless, repeater tracking system. The difference of this system versus a lot of them that are out there considered RFID systems is that the connection infrastructure is wireless between nodes, and the tag-tracking units have quite a bit more capability; they are not dumb units. This picture would be this device here. Your wireless node reader/repeaters are these. These systems are actually installed in a number of secure places in this town, protecting some important people. This is not made by us. We integrate and have a cooperative arrangement with the outfit that makes these. They are made in the United States. Here are some close-up pictures of Wi-PAD. We call it the wireless personal alert system. It gives you a pager -- let me see if I brought mine up here with me -- a little housing like this like a pager-sized device. It's got some buttons on it, though. Those are emergency alert. That signals the information back to capture software, and that software shows the guy's location at all times and that he's got a problem. If he goes down for a certain number of seconds, it will also activate at a man-down alert level, which is the highest alert level, and be captured by software on the surface, and the people can take appropriate action, all the time tracking the guy to the resolution of the reader/repeaters in a facility. So we've got man-down alert, position reporting to the capture software, cableless network between reader/repeaters, with a 24-hour battery pack there, and post-event survivability is 24 hours. All right. So you get all of these features. Our next technology level with that is we're going to put VOIP transmission on that unit so it will be one-way voice communications out of the mine with that unit as a backup to other systems. So in this diagram, we've got two layers here. We've got a UHF layer using a standard, portable radio in the facility that gives you that high-frequency, UHF range that you want in a mine, and it's got a layer on it. That's the Wi-PAD layer that is wireless between nodes. We're also running 900 spread spectrum. It's an extremely efficient radio, and the ratio of power to range is tremendous and very low energy use. Some other technologies; we've got a data technology that we use that the United States railroads have asked us to put in some of their facilities. We did it for them. It gives you the options of layering in rock mechanics and gas sensing. In MSHA, you guys might know, there has been a little change in the stench gas requirements in mines. In a hard rock mine when there is an emergency, they will release a gas that smells like rotten eggs, and they have changed the way they bottle that gas now, and the mines have got us building out wireless relay nodes with the press of a button that says stench on the screen. Mine management can flip that on with a shifter, and they will get those to trip and get everybody out of the mine with the gas. So advanced options; on these portables, it's amazing. It was mentioned, how are we going to keep track of somebody that's out of site or out of radio communications in a mine? The portables have a feature called lone worker now that reminds the guy that he needs to check in. It's all done inside the radio. This is common, state of the art with more advanced portables. It's available off the shelf. It's nothing that we do. IP-based systems are out there now. If you've got a LAN system, an Ethernet system in your mine, you can interconnect wireless base stations underground over that, and you automatically get tracking with that over the IP network that locates it to the resolution of your IP translation device. I'm going to zip right through here. I think we get the idea. Closing thoughts in my 20-some-odd years of chasing these mines. Mining is an industry. Last we checked, we were rated 19 out of 20. Does anybody want to guess what number 20 was? The tobacco industry. I would say we could use some improvement in this area, and I'm really happy that we're bringing this to the forefront because I think technology will help us. I've got a Bible verse there that says: "The Lord, your God, is bringing into a good land, a land of streams of water with wheat and barley, a land where bread is not scarce, and you'll lack nothing, a land where you can mine iron and copper out of the hills." It's just God's plan for a sound economy: mining. You've got to love it. A tribute to the guys that got me into this business. The late Al Isburg wrote a very definitive work in 1981, what I based some of my technologies on, for the U.S. Bureau of Mines on wireless in underground in Black River Mine, and then we sold the system in the Black River Mine. We have mine-wide, wall-to-wall coverage in that mine with two-way portables right now. The other guy is Bob Haning. Bob Haning is one of the three guys that invented leaky feeder systems, this whole leaky feeder technology. He is one of my mentors. I'm in communication with him weekly. Thank you very much. MR. STONE: Thank you. Could you just spell your name for the record? MR. ROSE: Mark Rose, R-O-S-E. MR. STONE: Thank you very much. Our next speaker is James Hackwood. Would you please come forward? And, again, could you begin by spelling your name and stating your affiliation? MR. HACKWOOD: Just to keep going, my name is James Hackwood, H-A-C-K-W-O-O-D, and I'm with the company, Northern Light Technologies from Toronto, Canada. I have also been in this business for about 20 years, starting with medium-frequency, inductively coupled or parasitically coupled technologies, leaky feeder, broadband communication techniques using cable television, and these kinds of things. We've used it for various aspects, from voice to full automation in tele operations, so I do have a little bit of experience there as well. (Pause.) MR. HACKWOOD: Thanks, panel. Thanks for this opportunity. Sorry for the delay. I guess I've lost two minutes. I've got about 14 slides, so at a slide a minute, I'll make up some time. I'm here today to talk about what I call the next generation of technology in communications. An earlier speaker spoke towards using Ethernet and wireless LAN technology as a viable solution. We believe the same thing, so I'll talk to some of the things we've done in this area. From the perspective of intrinsic safety and permissible devices, we have also got a partnership with a firm in Germany who has an intrinsically safe, approved, access point for use in coal, and some 300 units have been installed at the DSK operations primarily for the purpose of automation, but we can talk about those. With each one of these technologies, I'll also speak to where we are in the MSHA approval process. Our primary area of business over the last 20 years has been in the cap lamp manufacturing area. We like to think that this is the miner's number-one safety tool, but a respirator is pretty important in an emergency, too. This particular device is one of the latest cap lamps. This one has a two-way, Wi-Fi radio in it with a two-line display. I would be happy to pass this around just so you get a sense for the integration that's going on within the cap lamp itself. Certainly, over the years, we've installed RFID tags in the lamps. Some 3,000 or more tags have been installed in lamps in Chile. RFID is not a new technology, but there is a wonderful power source in the cap lamp that keeps the tags running all the time. We've also incorporated, the mouse is showing here, a two-way radio within the cap lamp, and this has been done from an ergonomic perspective for a lot of the mines that are using leaky feeder technology. Our lamps have also been involved, in addition to radio and tagging, with the PED technology, which we've heard about earlier. We have an MSHA-approved PED receiver that is installed in the cap lamp. The next versions of that to come out will also incorporate lithium-ion battery technology, which will give a lighter cap lamp again. We've also been approached recently by the firm, Vital Alert Communication, who I worked with some 20 years ago in the area of through-the-earth, emergency communications, and they also need a lamp for their receiver, so we're talking towards that cooperation. The other area of our business is in the area of communications, and we are coining the communications phrase "Northern Light Digital." The reason for digital is we want to turn the mine into a digital mine, and that incorporates all of the different aspects of data, voice, and video. The four areas of our focus at the moment, though, are in the area of voice-over IP, or two-way voice communications; two-way messaging, with that particular lamp there; tracking technology using RFID and Wi-Fi tracking; and ventilation management, and all of the aspects that go along with air flow monitoring as well. So those are the four areas of our focus with communications. So the Northern Light Digital Network is an open standard, IEEE-802.11ABG. It's commercially available, per the earlier speaker, and we have used Cisco in our systems as well, and that works very well. We've also used a couple of other approaches. We have units operating in the mines. In particular, I mentioned over 300 intrinsically safe units operating at the DSK mine. The advantage of the Ethernet network is that all of the kinds of applications that you might want to operate underground can be used across the network, including telephones, messaging, machine control and automation, data and supervisory control and automation. So there's plenty of things, an opportunity for this network to take advantage of your daily needs related to communications. This is a fiberoptic network that perfectly amenable to having dual fiberoptic rings, or more than dual, triple, however many you need. You can create redundant paths for fiberoptic cabling. So, we spoke to ring topology. We also have technologies that in the event of a hardware failure, you can actually have a mechanical switch that sort of heals the fiberoptic cable if you will. Those things are available. We also speak to wireless bridging, and that is where a link can be created between two wireless access points, and that of course provides a redundant path as well. Further to that, in the event of an emergency, portable repeaters, which again are simple off-the-shelf devices, can be used as the mine rescue team enters an emergency situation, and they can carry portable repeaters to heal the network during those situations. Another term that is important is interoperability, because we are operating on a standard. We can talk to and integrate with many other types of communications systems that might be present. So that your investment in the Legacy Systems isn't lost. So standard access nod, a very simple panel box, such as this, and this would be used for a hard rock application, or a surface wireless coverage, consisting of a programmable PC to do all the functions related to an access point, and power supply backup, and it functions as an access point. Now, there is enough room in the box, of course, to install optional RFI readers for tracking purposes, or PLC for controllers for data applications. This is a picture of the intrinsically safe access point. It also has a four port fiber switch in it, and this is used--again, I mentioned that the DSK mine in Germany, the primary purpose is to create a wireless link to an overhead trolley system that they use for men and material transport. We don't see too many of those here in the States, but it is approved to ATEX, and we will be submitting this device to MSHA in the coming days, in fact. So, voice over IP technology, you have probably heard about it in your day to day life. There is industrial handsets that are available. This is not intrinsically safe, this particular unit, but it is industrial. It also provides a press to talk capability, which miners like, and which behaves much like a two-way radio. We also have an intrinsically safe PDA. This is approved again to ATEX. This is also manufactured in Germany. To get voice from this PDA, you use something called a soft phone, and the image here actually is a video image that is being streamed from that automated trolley system that I spoke about earlier. So it also has got some capability to be a full-fledged computer and supervisor. Five minutes. So that means five slides, right? The digital messenger, you have seen in the audience there. It is a WiFi radio. You have web-based software that operates on your network, that anybody with web access, including wireless web access, could send a message to the unit. The key differentiator with this messenger unit is that it is a two-way device. So we communicate to it and the message is sent, and the system logs that it was received by the unit, because it has a full two-way session. In addition, we ask the operator to use the little toggle switch on that unit to confirm receipt of the message. It also has the ability to send a message by holding the toggle switch in a holding position for a few seconds, and that will send an emergency message. RFID tracking. Again, this is not new technology. It is used in many mines around the world, and this particular one is manufactured in South Africa. This can be a standard alone unit that fits in your pocket, or it can be mounted in the cap plant. And we saw this little device earlier today by the other speaker. This is a technology manufactured by AeroScout. It is a WiFi tag. The advantage here is that if you are putting in access points and wireless infrastructure, you can use that existing infrastructure to do all these different things, including tracking. So again you are not having to add other readers to the network. And of course the advantage that we have all spoken about is visibility for personnel, equipment, and assets, particularly visibility of where the person was during an emergency or after the emergency. And, of course, on the environmental side, we believe that this is an important aspect of a holistic approach, because we can actually provide early warning and launch preventive measures if we have enough data and knowledge about what the transit, and perhaps the gas levels mean, and rising temperature levels, or perhaps even rising CO levels. So these can be monitored on the system, and by integrating it with messenging, we can now alert people that are in a given zone of hazard, and prewarn them of possible problems. So it provides visibility in emergency, and of course, you have additional capabilities, in terms of real time reporting; compliance reports, and whether that is required or not in terms of monitoring of data. And wireless access to business applications, and because it is a standard network, you can also do your e-mail if you wanted to underground, or perhaps not the face, or do some of your other job functions while you are underground. And, of course, daily coordinating of maintenance personnel, or even production personnel, and redeploying them as required. And, of course, we have not talked much about the role of automation with respect to preventing accidents and that kind of thing. And there is a real push to perhaps consider the role of automation, and keeping the men out of harms way. So it is a modern communication technology based on an open standard. International certificates. Certainly we heard earlier today from MSHA that they would be considered in terms of fast tracking approvals. So we expect to leverage some of those, and of course the unified network gives you day to day functionality, but in the case of an emergency, you also have the added benefit of visibility. And redundancy and network healing is certainly a feature that can be employed in this kind of network. Thank you. MR. STONE: Are there any other questions? MR. CHIRDON: Yes. James, you mentioned that you have a cap man version that incorporates a two-way radio? MR. HACKWOOD: Yes. MR. CHIRDON: Is that used in a gassy mine somewhere, or -- MR. HACKWOOD: Well, when the HT-1000 was available, it could have. It was a permissible radio. We have since been asked -- and I think maybe on the two versions that you are looking at, we have been asked to redo our -- it is basically the radio stays intact, and it sandwiches in the lamp. And we have to redo the fittings basically. MR. CHIRDON: Oh, I see. There is no electrical interconnection between the devices? It is just a holder for the radio? MR. HACKWOOD: Well, you take the battery off and the use the cap lamp battery. MR. CHIRDON: Oh, I see. MR. HACKWOOD: So there is that electrical connection there. MR. CHIRDON: Okay. MR. LUZIK: I had a quick question. You were talking about the DSK mine in Germany. Is that a coal mine? MR. HACKWOOD: Yes, absolutely. MR. LUZIK: Do you have any information regarding the installation details and the experience with regard to that system that you might be able to provide? MR. HACKWOOD: I can provide that for you. MR. LUZIK: Yes, that would be helpful to us. MR. HACKWOOD: Yes, absolutely. MR. LUZIK: Thank you. MR. STONE: Thank you very much. Celina. Celina would like to make a technical remark for us. STAFF: Are we going to take a break? MR. STONE: Well, in a minute. STAFF: Just a small announcement for presenters that we have left. We do have laptops that we provided, and if you have presentations that are on a laptop, we can put them on a flash drive and put them on that laptop so you don't have to unload and load again. If you have a CD, we can also -- if we can get that ahead of time, we can get that set up for you as well. If you need a laptop set up, could you please let myself or people in the back know, and we can probably get that done during the break, as that will make it an easier flow during the rest of the day. Thank you. MR. STONE: Thank you. I would also like to repeat in case some reporters came in late, that members of the press should refer any questions that they might have to MSHA's press officer, Dirk Philpott, who is standing there. And he will be available during the break. And in mentioning a break, before the next scheduled speaker, I would like to take a 10 minute recess. I have about 10:25 now, and so we will convene at 10:35. (Whereupon, a brief recess was taken.) MR. STONE: All right. We are going back on the record. All right. Our next speakers, I believe, are Tony Bumbico and Wendell Christensen. Please begin by spelling your names and stating your affiliation. Thank you. MR. BUMBICO: Good morning. My name is Tony Bumbico, and that is spelled B-U-M-B-I-C-O, and I am the corporate safety director for ARCH Coal; and with me is Wendell Christensen. MR. CHRISTENSEN: That is Wendell Christensen, C-H-R-I-S-T-E-N-S-E-N. I am with ARCH Technical Services. MR. BUMBICO: Okay. We are here, similar to Mr. Bierbower, to present the operator's perspective on this issue. ARCH is the second largest coal producer in the United States. Our corporate office is in St. Louis, Missouri. We have over 3,500 employees, and operate mines in Colorado, Kentucky, Utah, Virginia, West Virginia, and Wyoming. Wendell supports our underground mines in Utah and Colorado. We are here today in response to MSHA's request for information on mine communication and tracking technology. Our specific objective today is to share our experience with the personal emergency device, or PED System. We appreciate the opportunity for comments. We had hoped that our experience will assist MSHA in future decisions related to the subject. PED systems are installed at two of our underground mines; at Dugout Canyon, and at Sufco. Both operations are large, long wall mines, with excellent safety records. Now, Dugout is located near Wellington, Utah. It has 223 employees, and is projected to produce about 4.6 million tons of coal in 2006. Sufco is located near Salina, Utah. It has 320 employees, and is projected to produce 7.6 million tons this year. The PED system at Sufco was installed in 1998, at a cost of $169,000. Dugout installed their system in 1999 and 2000. Both systems were purchased from Mine Site Technologies, or MST. At both mines, the PED was installed as a secondary communication system, as a backup to the primary mine pager system. Our relative success with the PED at these two operations is best described as mixed. At Dugout, the PED was originally deployed on a limited basis. It has since been expanded to its current state, in which approximately 50 percent of the workforce at Dugout carries a PED cap lamp battery, with a PED screen. The system at Dugout has been fairly reliable. There are ongoing issues related to interface with the mine pager phone system that require ongoing maintenance. Overall communication coverage has been good, up to distances of five to six thousand feet from the underground antenna loop. Dugout plans to install a leaky feeder radio system later this year. They also plan to maintain their PED system until a better alternative is available. In addition, Dugout is reviewing alternative mine retracting technologies. We plan to test MST's tracking system and other similar systems at Dugout later this year. Sufco has had less success with the PED system. As a result, they have deployed the PED on a more limited basis. At Sufco, PED units were initially issued to supervisors, electricians, fire bosses, EMTs, and miners working in out bay areas. The PED system itself at Sufco has not been reliable. The system interferes continuously with the mine pager phone system, and the mine monitoring system. To date, efforts by the manufacturer and Sufco to resolve these problems have not been successful. As a result, Sufco discontinued the use of their PED system when they installed their leaky feeder radio system in 2004. Our experience with the PED has identified some common issues. I will offer some brief comments on a few of the more significant problems that we have encountered with the PED. I am sure that there are some reasonable solutions to some of these issues. Others present more significant technical challenges. One common PED issue is infrastructure maintenance. As an underground mine advances, you have to continually extend the antenna system. Large minds like Dugout and Sufco have to install thousands of feet of antenna in order to maintain the loop. Dugout has approximately 45,000 feet and Sufco has approximately 50,000 feet of underground antenna cable. Failure to maintain this infrastructure results in dead spots in coverage. We have encountered dead spots at both operations. This is more than just a maintenance issue. It has potential enforcement implications. We know from experience that periodic dead spots will occur. We are concerned about how MSHA will treat these incidents from a compliance standpoint. If regulations require the PED to be installed in all underground mines, will MSHA issue violations if we encounter periodic dead spots? Would we have to evacuate the mine. Given the recurring nature of this problem, these are issues that our operations are concerned about. We need more reliable alternatives. Another issue related to the PED, as well as other communication and tracking systems, is the vulnerability of the underground infrastructure. As MSHA is aware, this hardware is susceptible to damage from explosions, fires, and roof falls. In addition, the explosive atmosphere in a mine following a disaster may render the system inoperable for safety considerations. In one respect the PED system is more vulnerable to damage than other underground communication systems. In order for the system to operate the PED antenna must form a complete loop. It requires twice as much cable as other underground communications systems. As a result, it is twice as vulnerable to damage from explosions, fire, or roof falls. Some have proposed surface loop antennas as the answer to this dilemma. In some cases a surface antenna may work. They are not the universal answer, however, because at mines like Dugout or Sufco, the depth of cover may exceed two thousand feet. Many mines, particularly those in the Western States, we have to deal with surface rights issues, and installation complicated by rugged terrain, to consider installing a surface antenna. Our experience indicates that the PED system tends to interfere with other communications systems. This problem has been more significant at Sufco than Dugout. At Dugout the mine pager phone system occasionally experiences a feedback noise when the PED is operated. This problem is normally a grounding issue that is created when the loop antenna comes into contact with the wire mesh used to support the roof and ribs. When this occurs, they have to turn off the PED system after they send the message. At Sufco, the feedback problem has been more persistent. It affects not only their mine pager system, but also the mine monitoring system. We are not sure what causes the feedback problem at Sufco. It may be the result of the PED antenna running near high voltage cables, or cables that are not shielded. Since we have been unable to resolve this issue, the PED system is currently inoperative at Sufco. We have also experienced problems at both mines using the PED to communicate with employees in pickup trucks. As you are aware the PED system alerts the miner to a problem by causing the cap lamp to flash off and on. It also has a secondary alarm that alerts the miner to a message. At many underground mines, miners travel to and from their work place in pickup trucks. If a miner leaves his or her cap lamp on in the pickup truck, it creates a glare that obstructs their vision. To avoid the glare the cap lamps are turned off while they are in the truck. Consequently, the miner isn't aware when the light flashes on and off to alert them to a PED message. Often the secondary alarm of the PED is not loud enough to be heard over the noise generated by the pickup truck or other mining equipment. A possible solution to this issue may be a more effective secondary warning system to alert the minor to a PED message. Seam height is another factor in the effectiveness of the PED and some other underground communications systems. The seam height at Dugout averages 8 to 9 feet. At Sufco, it normally exceeds 10 feet. As a result the PED systems would tend to be more effective at these operations, as opposed to mines with lower seam cover. The most significant issue that we have with the PED is that it is only a one-way system. You can send a message, but you never know whether it has been received by the miner. The PED system represents an improved emergency notification technology, but it is limited. We feel that underground coal miners need and deserve better emergency communication options. We feel that MST is a good company with a good product. Their PED system was clearly a major factor in the successful evacuation of the Willow Creek mine in November of 1998. A PED alert sent by the Willow Creek supervisor helped to evacuate 45 miners in 45 minutes. We play to continue to evaluate the PED system at Dugout and Sufco. In addition, we are also evaluating MST's PED and tracker systems, as well as other similar technology, designed by other companies at a number of our other mines. The PED represents an improvement in emergency communication technology. In the final analysis, however, it is not good enough. We need to identify, test, and install better communication and tracking technology. We need technology that can provide two-way communication with miners underground, precise tracking of the miner's location, and infrastructure capable of surviving a fire or explosion. We are encouraged by the recent research initiated by MSHA in this area. In our opinion the agency has identified several new communication technologies, with the potential to achieve our objective. Many of these technologies have been used by the military and in other industries. In particular, we are encouraged by the promise of systems such as the Rajant Breadcrumb System, the Time Domain Radar System, the Vital Alert Canary 2-way Mine Messenger, the TG Miner Tracker System, and the Buddy Tracking System. ARCH support the research effort initiated by MSHA in this critical important area. We are willing to offer our mines as possible test sites for these new promising communication technologies. We are willing to work with MSHA, NIOSH, and other interested parties, to develop and implement improved emergency communication options for our employees. However, we want to stress the importance of testing these technologies in real life mine environments. Underground mines come in many shapes and sizes. Geological conditions vary significantly from region to region. Issues such as seam height, depth of cover, and surface terrain, all have an impact on how well the technology will work. What works at one mine may not work in another. The final solutions proposed by MSHA need to recognize that one size does not fit all. In order to improve emergency communications for our miners, we need a flexible approach that recognizes the unique characteristics of each mine. It is imperative that we identify the best available technology, and test it in a real life mine environment to make sure that it is reliable. We appreciate the opportunity to appear and offer comments, and we are willing to try to answer any questions. MR. STONE: Thank you very much. Steve, do you have any questions? MR. LUZIK: No. MR. STONE: Thank you very much. The next speaker is Jeffrey Rummel. Please begin my spelling your names and your affiliation. Thank you. MR. FISHEL: My name is Alan Fishel, and I am here with Jeffrey Rummel, and we both work at Arent, Fox; A-R-E-N-T, and then the next word is F-O-X. And that is a law firm in Washington, D.C. And my name is A-L-A-N, and my last name is F-I-S-H-E-L; and Jeffrey is J-E-F-F-R-E-Y, and his last name is Rummel, R-U-M-M-E-L. We have a very brief presentation. I am going to speak first for just a couple of minutes, and then Jeffrey is going to speak and get into a little more detail for just another couple of minutes. We promise to keep this very short. Basically, we are Federal Regulatory Attorneys in D.C. who have represented both a number of mining companies, and mining manufacturers, on a variety of issues. I just want you to take a second to picture this situation, where you are in a situation as a mining company or a mining manufacturer, where you have done exactly what you thought you were supposed to do, and looked in the MSHA rules, figured out what you needed to meet, come to your own conclusion that you have met MSHA's requirements, at least in your own mind. You started making some production or whatever else, and starting to purchase equipment, and all of a sudden down the road the Federal Communications Commission comes to you and says you violated the law. That's great, you know. You complied with what you thought was MSHA, but you have violated the law. And now you are going to your boss and explaining why you did not consider the FCC and Federal communications involved. And unlike in a Super Bowl commercial with FedEx, where FedEx didn't exist, the FCC does exist now. And it is important, and it happens all the time, where people in one industry, whether it is mining industries or other industries, where they have overlapped with the Federal Communications Commission, and just for good reasons at times, but just forget -- well, when I say good reasons, it is understandable why it is not a good reason. But understandably just forgetting about the FCC, and they shouldn't, because it can come back, and you want to make sure that you have done that. We have represented mining companies at the FCC, and we have done other Federal regulatory work. An example of that was a major proceeding going on a couple of years ago where we represented what was known as the Private Wireless Mining Coalition. And this was a case in which before we got involved, the mining companies had lost on a major issue that was going to cost them a lot of money. And they came to us to try to get that reversed, and everything worked out fine, and it did get reversed. But the reason that it started that way is something to note here, which is simply that people didn't realize everything that was going on at the Commission because mining companies focus as they should on MSHA as they should and as they need to do. But at times the FCC also plays a role. Here, mining manufacturers have to worry about equipment authorizations, and mining companies have to worry about licensing frequencies and emissions, and it is just important to note that at the Federal Communications Commission. And by the way, on that proceeding, I should mention that we did work very well with the National Mining Association, who was very, very helpful in coordinating on those other FCC issues. But with mining companies, you need to remember that at the Federal Communications Commission, just like with MSHA, you can have significant fines, and even shutdowns. I mean, one company just a month ago, and this was not a mining company, but it was noted that on equipment authorizations the proposed fine was a million dollars. Now you don't see that every day at the FCC, but you saw that just last month on that sort of an issue. Once again, it was an equipment authorization issue, outside of the mining context. But it is important to note. And finally, Jeffrey is going to go into more details on everything, but he is going to talk a little bit about some of the rules that you need to keep in mind. But one thing to mention up front is that if you don't feel that you can necessarily meet all of those rules, one potential option is to go to the FCC sooner rather than later to discuss the possibility of a waiver. Waivers are often granted. Well, often they are not granted, but when they are granted, they are granted because they are in the public's interests. You will have arguments to make here, and because the rules that you would be getting waived, their purpose would not be undermined by you getting a waiver in that instance. So it is important to keep in mind a variety of options that you will have, and Jeffrey will go into a little more detail on that when you are going to the Commission. And one last thing is that we see a lot of times that people go to the Federal Communications Commission at the very last second, saying that I have been designing something for five years, and I would like for you to waive your rules tomorrow. It is obviously much easier to do that if you start earlier in the process, and give them a heads up that this is what you are trying to do, because the equity thing will favor you, and you are in a better position. We would be happy to answer questions after Jeffrey's presentation as to the rest of it. Thank you very much for giving us the time. MR. RUMMEL: Thank you, Alan. As Dave mentioned in his initial presentation, one of the key concerns in this proceeding in finding the right technology is interference, and the FCC's rules are specifically designed to prevent interference on RF signals, to co-channel, and adjacent users. The requirements of both MSHA and the FCC should be addressed with respect to interference by both manufacturers and mining companies, and that is a particular concern because the requirements that are being discussed both at MSHA and in Congress are discussing two-way communications, which include communications from the surface, where you are out in the environment, to underground environment as well. Basically, communications equipment can be approved by the FCC on a licensed or unlicensed operation basis. Regarding or leading to unlicensed basis authorization, unlicensed authorization is beneficial, because this means that mining companies would not need to obtain their own licenses to use the equipment. This makes the technology much more appealing to industry. However, there are requirements that still must be met by manufacturers, and that involves in many cases getting the equipment authorized under the FCC's equipment authorization rules, which includes very specific testing, labeling, and user manual requirements. The systems are not permitted to just transmit on any frequency. The FCC rules designate certain restricted bands which cannot be used under any circumstances. In addition, in certain underground operations, there is a tunnel radio system rule, for example, and emissions limits above ground are limited. Now, a lot of the information regarding tunnel radio systems, and their problems with underground operation, are obviously more problematic when you are talking about when those systems relate to above ground communications as well, from above ground to the underground. And those are dealt with on an unlicensed basis, but there is also in most situations, you have to look at licensing operations as well. And licensed operation means that the users of the equipment must get their own license to operate, and that would be the mining companies themselves. That does not, however, relieve the manufacturers of the need to get their own equipment authorization under the particular FCC rule part, which allows for licensed operation. So, for example, you may know at certain mining locations that you use two-way radios for above ground communications. Those may be Motorola radios, for example. Motorola has received an equipment authorization for those radios to operate in accordance with FCC specifications. But mining companies are required to get the license to operate those hand-held walkie-talkies. So it is a problem and an issue that both the manufacturers and the mining companies need to be aware of. For manufacturers, we suggest that you figure out right away whether you are proposing a system that falls within the unlicensed or the licensed regulatory requirements of the FCC. Many of our clients develop technology that is great functionally, but does not neatly fit within either the unlicensed or the licensed regulations. That's okay, because as Alan mentioned, there are ways to deal with this. Waivers, for example, as Alan mentioned, the FCC is willing to grant, even if your proposed operations deviate from the requirements if you can meet certain legal standards and technical requirements. However, you do need time to identify how far you deviate from the FCC rules, and you must develop your waiver requests. Often you should meet with FCC staff in order to coordinate the requests, and then have the appropriate contacts to push that waiver request within the appropriate time frame. You can also request temporary authority from the FCC on a variety of situations, where you can't meet the time requirements that your business requirements are imposing upon you. Again, very specific legal requirements and showings are involved when you are requesting temporary authority. Finally, if all of these issues regarding equipment authorization or licensing, or unlicensed operation, present too many obstacles, and you are too far from these normal FCC requirements, you can also seek experimental licenses. We are heavily involved in that area, and it is a way to get your equipment up and running without necessarily being subjected to the full panoply of regulations. Alan and I, because of other commitments, won't be able to stay the entire day. We will be here through the lunch break, and we will be standing at the back of the room, and we will have copies of the comments that we had filed in this proceeding if you are interested. And we have a copy of the rule which lists the FCC's fines as well. So if you have any questions, we would be happy to discuss them. MR. STONE: Steve, do you have any questions? MR. LUZIK: Not really. MR. STONE: Thank you very much. MR. RUMMEL: Thank you very much. MR. STONE: Our next speaker is Gary Tydings. Please come forward, and begin by spelling your name and stating your affiliation. MR. TYDINGS: We will get the computer working first. MR. STONE: Okay. We will do that, too. MR. TYDINGS: Gary Tydings, G-A-R-Y T-Y-D-I-N-G-S. And I am representing from beautiful Raton, New Mexico, Stolar Research, Stolar Horizon Technologies. I want to preface the remarks very briefly by saying that the founder of the company, Larry Stolarcyk, who many of you know, is very passionate about this issue. And maybe passionate is not even a strong enough word. He has since the disaster in West Virginia spent an inordinate amount of time putting together what amounts to a treatise which consists of things such as Congressional White Papers, suggestions for regulatory change, suggestions for legislation, and has spent a fair amount of time up on The Hill trying to push this issue. One of the reasons that I am here this week was to assist in the briefing of some Congressional staff on this particular issue. But what we are going to talk about today is some technology that is pretty far past the developmental stage, and in some cases is operational, as to a multimode two-way radio communication for emergency and operational conditions in mines. It is self-explanatory. Why is this company deeply involved in it, and at the behest of the founder of the company, in 1984, Larry lost 12 friends, very close friends, in the Welburg Mine, Quecreek, and then the Sago Mine explosion. And mine wide wireless two-way radio communications is critical for the solution of these problems. What are some of the features that should be involved in this, and I think that most of the people here have heard this morning, and they are trying to incorporate or have variations on this theme, wireless two-way transmission, natural waveguides. Through the earth waveguide, using an ultra low frequency, conveyor belt and cable waveguide also using a low frequency. Coal seam waiver guide and low frequency, and passive wave waveguide, and ultra high frequency. It has to be intrinsically safe, and it has to be operational when ventilation is disrupted. What are some of the features that we are developing? It will be a three redundant tracking and location, with subsystems, and real time networks, surface Delta tracker, and I will speak a little bit more about the Delta tracking. And then what is known as a Fox Hunter Antenna. It has to be extremely reliable, and I believe that testing will verify this. It has an F1/F1 repeater expandable and self-healing, and it goes through the earth with a redundancy, and is modulated for digital transmission. For tracking systems, cap lamp, power tracking beacon, cap lamp receiver, and it is multimode, and it is two-way tech synthetic voice capability, with a bluetooth link. And this is sort of an outline, and I'm sorry that the details are a little bit small, but sort of, you see a holistic, more or less holistic communication and tracking system. For tracking, the beacon goes through the earth using the earth as the waveguide, and above it is what is known as the Delta Tracker, which can either be airborne or man-held. This is a tracking beacon, and this is an older version. This is a Delta Tracker, and it is an EM gradiometer, and it not only suppresses the radio frequency interference that you might find on the surface, but the text spreading EM, and it pinpoints miners' locations, and it can determine depth. This particular EM gradiometer Delta Tracker has been developed and is being used. About half of Stolar's business involves the U.S. Government in one way, shape, or form, and generally the Defense and Energy industries. The other half is the energy, coal, oil, and gas, et cetera. It detects voids, and without me having to spell it out for you, you can see that where the applications would be for use by the military, and the military is using this thing right now. Now, what we spent a lot of time on, and what Larry is very passionate about, is the regulation change that he feels, because there was not required in the current regulation that just says that you have got to have wired communications, which we all know is the first thing to go, is to combine the 30 CFR and the 30 CFR 49. And require the same network and equipment, and require a 96 hour system operation when the ventilation system is disrupted. These three elements, he feels and we feel, and I am begging to get some impressions from talking to some of the staffers on The Hill, that they feel that this might be a direction that should be taken. What else do you want to do? Well, I think one of the things, and I think Senator Rockefeller maybe has already taken care of some of this in the budget reconciliation, but this equipment can be very, very expensive, and it needs to be incentivized in some way, shape, or form. Perhaps there could be tax credits for the purchase, and the installation, and the maintenance, and the training of sufficient personnel. I think probably these are some of the areas, in addition to the technologies, that Stolar is very heavily involved with, and is developing. And I suspect that if you don't already have a proposal from Stolar, there is probably one on your desk today, and I assure you that it is a magnum opus. So hopefully the company will be in the mix, and in fact, right now I think that some of the things that you have already identified, we will be participating in with some of the other companies already. So, in conclusion, I think this is a two-pronged approach. I think it is critical for the regulations. We feel that it is very critical for the regulations to reflect technology at its best and current form, and provide incentives to see that that technology is implemented in its best and current forms. Thank you. MR. STONE: Thank you. Our next speaker is John Brigler. Please come up. Is John Brigler here? Okay. So, our next speaker is Marty Sargent. Please come forward. No? Okay. Marty Sargent? All right. Our next speaker is Donnie Gatten. MR. GATTEN: By default. MR. STONE: Again, please begin by spelling your name and stating your affiliation. MR. GATTEN: My name is Donnie Gatten, and I with Technical Training Consulting. It is a mine safety and training firm. My past history, I am a fourth generation coal miner, underground coal miner. I have been in the mining industry over 20 years, and have about 20 years of mine rescue experience as well. I will be pretty brief. I asked for about five minutes, and I think they allotted me 10, and so this probably won't take real long. My main concern is from a mine rescue standpoint. I currently train coal, non-metal, and tunnel rescue teams, and I think that some of the other industry people expressed the same concerns, but something that is actually going to work after a disaster situation. I think the same concerns that you as a group have as well. The leaky feeder systems, depending upon a hard wire underground, or a loop on the surface, poses problems with failure because of the hard wire underground. And then on the surface, in a lot of situations, they may work, but in many others, they also have problems as Mr. Bierbauer spoke of with the terrain out West. And then we also have mines that go on to rivers, lakes, and places like that, where it would be hard to establish a communications look at well. We have had two or three speakers that have talked about some new emerging technology, and the last one being one of those. The thing that I would urge you as a panel, and as a regulatory industry, as we look at new laws and regulations, is to take the time to look at the facts, and not base anything on theory or opinion. As a mine rescue member, I know that there is a lot of emotion involved after a tragedy, like Sago, from a political side and from a family side. There is probably nothing that focuses more on safety than having to put someone in a body bag, and I have been there and don that. And it is difficult to separate that out when you are looking for something that is going to work, and we are going to place in regulations for mines to have to comply with. To my knowledge, right now with current technology, as far as two-way voice communication, wireless voice communication underground, I don't know of anything, not just available to the mining industry, but any other entities out there right now that have that current capability. And I think that is the thing that we were really looking for. The real question is what are we going to look at in lieu of that, that is going to actually improve from our rescue standpoint our ability to get people, or know where they are, after an incident occurs. A leaky feeder system right now with a tracking device gives us information on where they were when the incident happened, at least maybe within five thousand feet. But not where they went to or moved to after that. Now, that could maybe be coupled with some of the other things that are on the table as far as shelter holes, and things like that, where you coordinate that through the training and regulation on maybe where people should go. But from the training side of things, what we want people to do is to try and exit the mine when an incident like this happens, and not necessarily look for a place to go and wait for someone to come rescue them. So I am afraid that if we are not careful, if we use something that isn't the technology that we are looking for, that we may end up giving people a false sense of security, or having them rely on something that is not going to make it safer, but may be detrimental to people exiting the mine. Another problem is that I know a battery backup is required on these systems, but from a rescue standpoint after an explosion, with the devastation underground, and the explosion coming out, it also has a recoil where it pulls back in -- and someone who has not seen it can't realize the devastation that you have underground. I know that some of you guys have probably seen that, but most of the people in this room probably have not. What was a permissible enclosure and which would keep an electrical arc from igniting an explosive mixture outside of that, may or may not be permissible anymore. And you have people on rescue teams going into these environments, where inside these permissible enclosures, you have electrical connections that could make or break, where after this, they could potentially set off an explosive gas. So it is a real concern from a rescue standpoint on having these connections underground throughout an entire mine system, and how varied that may be depending on the particular mine. Also, on the communication that the mine rescue teams themselves use, a lot of the miscommunication at Sago was a result of the type of communication the teams used. They typically use a hardwire line that is a thousand feet long. Our teams that were out there at that time -- and I am from the rescue community, and so I say our teams. We are all one big family it seems like. But the teams went well beyond their thousand feet capability on this hard line, and they were using radio communication in conjunction with this, relaying back to one another to get that information back to the command center on the surface. Better communication systems for the rescue teams themselves are something that I think we need to look at, as well as mine-wide wireless two-way communication. I know that there are some prototypes out there that integrate radio communication into this hardwire so that they can communicate between one another, and also have the capability to communicate directly to the command center on the surface through this system. To my knowledge -- and you guys can correct me -- I don't think any of those currently have an MSHA approval. I think it is pending on all of those. So we don't have that capability to use in a real situation right now. If we had had that type system at Sago, a lot of that confusion would have been completely eliminated, because the team that was up there, and where the people were found, could have talked directly to the command center outside, instead of having the problem with having to relay back through several people. Again, all of these systems that we are talking about are dependent on hand-held radios currently, and I think you said in your opening comments that Motorola doesn't have them on the market right now. As a matter of fact, there are no radios approved, MSHA approved, for use that are on the market, where a new rescue team, or even a new coal operator, or coal mine, could purchase radios to have to use. And Motorola, I think it took them over two years to get their initial approval on these radios that are not used now. Kenwood is one of the people that is seeking approval, and they are currently over two years trying to get that approved. So it is not a quick thing. It is something that takes time, and it should take time to get the quality assurance that we need to make sure that these things are going to function properly without creating a hazard for those using them. But the main point that I want to reiterate that has been reflected by some of the other speakers is we need to make sure that we do have quality assurance on whatever we do. We need to make sure that it is going to actually serve the purpose that we initially started out looking for, and that it will provide us with something that is going to increase safety, and not be detrimental to rescue teams, or create a hazard for them, or other people in the mines after the disaster, because if we are not careful, we could possibly create that situation. That involves as you said not just experimental mine simulations of these products. I think that can get you into thinking a product may work when it may not. Actual field testing in a variety of situations is what we really
