If the form is not completed the employee would be disciplined. Drill Operation Start  engine Start compressor Flip toggle switch to on position Start rotation Flip toggle switch to forward rotation  to left Turn on water Ball valve located in cab Engage air Valve located on top water valve Push feed tilt lever down Drilling the correct angle will ensure that the face will pull the maximum amount Ensure the correct angle of minus 18 degrees is maintained Position boom on the first bottom hole on fifth line from right rib. Push boom swing lever down Ensure the steel stays straight with the face (perpendicular) Release boom swing lever when lined over the bottom left hole to be drilled Push feed extend lever down until drill touches the face To maintain the optimal efficiency of the drilling operation, it is important to follow the provided drilling sequence listed in the job steps that follow. If obstruction and/or sandstone is encountered, the drill hole locations may have to be moved over a few inches.  Start drilling and make setup moves from right to left to stay ahead of cutter. Push feed lever forward to begin drilling Observed feed pressure gauge Pressure should read 400 psi maximum. If pressure exceeds 400 psi, adjust feed pressure according to manufacture specification.  Pressure chart is posted in cab. Observe shavings for dust control If area becomes to dusty add water accordingly.  If shavings become to wet decrease water. Listen and look for feed retract This would indicate the hole is completely drilled. Pull feed extension lever back to retract the feed extension Position boom to bottom hole on third line from right rib Pull the boom swing lever to swing the boom to the right Ensure that the boom is lined up with the hole then release the lever To minus 18 degrees. Ensure the correct angle of minus 18 degrees is maintained Continue to position boom and drill the remaining bottom holes until you reach the right rib Pull boom lift lever up to raise boom until marker on chain is even with bottom hole  on right rib Set boom angle to minus 16 degrees Pull feed tilt lever up Release lever when minus 16 degree is reached  Drilling the correct angle will ensure that the face will pull the maximum amount. Position boom to the second hole on the second row on the right rib Push feed extend lever until boom contacts the face Ensure marker on chain is even with bottom hole  on right rib Proceed using the procedures to drill holes as specified above To maintain the optimal efficiency of the drilling operation it is important to follow the provided drilling sequence listed in the job steps that follow Continue to drill hole up the right rib using the drill/angle pattern chart located in cab Each row requires a different angle. The angles are as follows: (from bottom up) minus 18, minus 16, minus 12, minus 6,  0 and plus 3 degrees. Position boom to number two hole on the second row from right rib using the levers and procedures outlined above Drill the number two hole on the second row of right rib using the levers and procedures outlined above Continue drilling holes according to pattern from right to left/left to right working up until setup is completed Shut off rotation Return boom to center Push boom lift lever down until boom is level with operator cab Lift on the boom swing lever to swing boom to right until boom is centered with arrow To prevent drill from tipping over Lift out riggers Pull lever toward operator to lift outrigger (there is four different levers that control all outriggers) Ensure that all outriggers are lowered/raised one at a time The levers are located on left rear side of operator seat Release park brakes Tram drill to next setup Stand up in the cab Ensure area is clear before moving to next set up If the cutter is in the room, make sure that you don't back over the cutter cable. Push tram lever forward and to the right  to steer drill away from face and toward the center of the room approximately 50 feet away from the face Release lever Pull lever to forward position to tram drill to center of next setup Steer drill and place boom approximately 3 feet away from face Release tram lever Apply parking brakes Exit cab Walk to rear of drill approximately 30 feet Visually ensure that the drill is square to the face If drill is not square to the face reposition drill accordingly Drill holes starting at the bottom left and continue left to right/right to left, using drill pattern until setup is completed Use drill controls and procedures as out lined above Tram drill to third set up Use tram procedures outlined above Follow same tram and drill procedure to complete third set up Tram to final set up along left rib Begin drilling the bottom right hole on the fifth line left of center Follow drilling procedures as previously out lined Drill right to left until last hole against left rib is completed Drill holes up left rib until last hole at back is completed according to drill/angle pattern specification Set up boom and begin drilling second hole second row According to drill/angle pattern specification Continue drilling left to right/right to left until last hole is completed According to drill/angle pattern specification Turn off rotation Turn off air Turn off water Center the boom following the same procedure as described above To prevent drill from tipping over Prepare drill to tram to next room Changing Drill Bits Lower boom to approximately 4' above floor Shut drill off Tag out drill Turn off master key switch located by the door of operator cab next to the second step Remove key from master switch and place key in drillers pocket Fill out tag and place on door Lock out tag out according to company policy Obtain hammer and new bit from tool box Located at right rear fender Don full face shield Hit bit with hammer to loosen bit Proper PPE as required per company policy Remove bit (unscrew) Apply never seize to new bit Install new bit and hand tighten Place old bit in bucket Bucket is located on drill inside cab Place hammer in tool box Remove tag from door Replace master key Turn master key to on position Changing Drill Steel Lower boom to approximately 4' above floor Notify supervisor that steel  needs to be replaced Obtain drill steel Tag out drill Turn off master key switch located by the door of operator cab next to the second step Remove key from master switch and place key in drillers pocket Fill out tag and place on door Lock out tag out according to company policy Obtain two 18 inch pipe wrenches from tool box Tool box located on right rear of drill Place one pipe wrench on the steel adaptor To prevent rotation of adaptor Place second pipe wrench on the steel Pull second pipe wrench down to break connection Remove pipe wrenches after the connection is broken Unscrew steel by hand and remove from steel guides Place old steel in truck History at this mine shows that steel has entered the mining cycle causing shut downs and loss of production. May put maintenance personnel in dangerous positions to repair or remove steel. Place new steel in guide Apply never seize to the threads Hand screw steel into adaptor until hand tight Install new bit into steel Hand tighten new bit into steel Place tools back in tool box Remove tag from door Replace master key Turn master key to the on position End of Shift Activities Ensure drill steel is not left in the drill hole Ensure air, water, and rotation are off Ensure drill is shut down Equipment should not be left unattended when it is running Leave job site approximately 45 minutes prior to end of shift and travel to lunch room Communicate with supervisor and turn in pre-shift and work place inspection reports Communicate to supervisor the drilling progress that was completed Leave lunch room approximately 30 minutes prior to end of shift Travel to 900' level production shaft Wait until supervisor calls the man cage (approximately 2-3 minutes) Enter the air-lock Close air-lock doors Open inside air-lock door and exit Close air lock after last person has exited the air-lock Ensure the man cage is spotted Ensure horn is sounded prior to opening shaft gate Open shaft gate Open man cage door Enter man cage Close shaft gate Close man cage door Ride man cage to surface after signal is given to the hoist operator Ensure that the horn is sounded prior to opening man cage door Open the man cage door Open shaft gate Exit man cage Close man cage door Close the shaft gate Release the man cage Walk to the change room Punch out time clock Save mine light and place on charger Tag out Replace PPE in personal locker Walk to vehicle
