End Dump Upended on Stockpile
On Friday, April 10, 2009, a near miss accident occurred at a District 8 surface coal mine. The incident occurred as a Caterpillar Model 777C end-dump truck was being maneuvered for dumping at a coal stockpile. As the truck driver was backing the truck into dumping position, the right corner of the stockpiled material broke away as the truck stopped, causing the truck to fall backwards down the coal stockpile. The truck came to rest in a vertical position trapping the truck driver. With the aid of a ladder truck, the truck driver was rescued. Rescuers gave the driver a safety belt to fasten to the ladder on the ladder truck, which help facilitate his safe escape. The driver did not suffer any injuries.
This near miss accident occurred because of an improperly located berm, which had not been located at least one loader length from the edge of the coal stockpile. Other factors resulting in the non-injury accident were coal had been removed from the toe of the stockpile, rainfall of ½ inch had occurred over night, and the dumpsite had not been properly examined before dumping.
- Examine dump sites once each shift or more frequently if needed.
- Properly locate and install berms to prevent over travel or overturning at dumping locations.
- At dumping points where ground may fail to support the weight of a loaded dump truck, trucks shall be dumped a safe distance back from the edge of the bank.
