www.msha.gov U.S. Department of LaborMine Safety and Health Administration Roof Fall - Underground - West Virginia FAC-C-01 COAL MINE FATALITY - On Wednesday, January 2, 2002, a 44-year old remote control continuous mining machine operator with 23 years of mining experience was fatally injured in a roof fall accident. The victim was mining in the No. 2 right crosscut of the 7 headgate section when roof rock measuring seven feet by five feet by three to five inches in thickness fell in the area where he was standing. The continuous mining machine had sheared off 7 roof bolts when starting this crosscut. The victim was operating the machine while under this unsupported roof at the time of the accident.

www.msha.gov U.S. Department of LaborMine Safety and Health Administration Electrical - Underground - Virginia FAC-C-02 COAL MINE FATALITY - On Thursday, January 24, 2002, a 43 year old general inside laborer was fatally injured while performing electrical work on the 12,470 volt underground power center located on the 001-0 section. During retreat mining a length of high voltage cable was removed. Problems were encountered with re-energizing the power at the substation on the surface after the cable was re-stocked in the section power center. The certified electrician came outside to check on the problem. When power was restored to the section it was discovered that the phasing was wrong. Power was removed from the section to correct the phasing. The victim was working on the leads inside the power center when the 001-0 section power was again re-energized from the surface, resulting in a fatal electrical accident.

www.msha.gov U.S. Department of LaborMine Safety and Health Administration Exploding Vessels - Surface - Virginia FAC-C-03 COAL MINE FATALITY - On Monday, January 28, 2002, a clean coal filter drain pump exploded due to steam build up within the pump, inflicting fatal injuries to the fine coal operator at a preparation plant of an underground mine. The victim was standing approximately 8 feet away at the on/off switch when the pump cover struck him. The pump overheated after almost all liquids had been pumped from the filter drain tank causing the remaining fines to solidify, thus preventing flow. The inlet and discharge lines then became clogged with coal fines causing the pump to become a closed pressure vessel.

www.msha.gov U.S. Department of LaborMine Safety and Health Administration Fall of Rib/Highwall - Surface - Wyoming FAC-C-07 COAL MINE FATALITY - On Wednesday, February 20, 2002, a 49-year old miner was killed by a fall of rock from a highwall at a surface coal mine. The miner was operating a Caterpillar Model 834 rubber tire bulldozer, cleaning the pit floor at the No. 8 shovel, when rock and material fell from the highwall striking the bulldozer. The massive block of material crushed the cab causing fatal injuries. The bulldozer was equipped with a falling object protective structure (FOPS)/ rollover protective structure (ROPS), which was not sufficient to prevent fatal injury to the operator. The ROPS/FOPS and cab were removed during recovery operations and are not visible in the picture below.

www.msha.gov U.S. Department of LaborMine Safety and Health Administration Powered Haulage - Surface - Utah FAC-C-08 COAL MINE FATALITY - On Wednesday, February 27, 2002, a 43-year old truck driver, employed by an independent trucking company, was fatally injured while loading an over-the-road haul truck at a surface load-out of an underground coal mine. The driver had loaded coal into both of the 20-ton, bottom-dump trailers that were connected to the truck, but coal had spilled over the side of the second trailer. The driver got out of the truck to check the spillage, setting the tractor brakes but not the trailer brakes. While he was outside, the truck began moving down the road that had an approximate 6% grade. The driver attempted to re-enter the truck and was thrown from the truck, and then hit by this same truck. The truck traveled approximately 200 feet before striking a hillside and coming to a rest. The driver had about one year of experience as a truck driver, and this was his first trip to the load-out where the accident occurred.

www.msha.gov U.S. Department of LaborMine Safety and Health Administration Powered Haulage - Surface - New Mexico FAC-C-11 COAL MINE FATALITY - On Friday April 26, 2002, a 61-year old mechanic/welder, with 16 years of mining experience, was fatally injured in a powered haulage accident while fueling a Caterpillar D11 bulldozer in the pit of a surface coal mine. While fueling the bulldozer, the victim's service truck began to roll away, down a 6-8% grade toward a Liebherr haul truck. The victim ran after the service truck, mounted the running board, and apparently slipped off and fell under the rear tandem wheels. The truck continued another 35 feet, struck the front of the Liebherr haul truck, and stopped. The service truck traveled approximately 225 feet before hitting the haul truck. Wheel chocks were found at the site. They appeared to have been used, but did not prevent the truck from moving downhill.

www.msha.gov U.S. Department of LaborMine Safety and Health Administration Electrical - Underground - Pennsylvania FAC-C-12 COAL MINE FATALITY - On Saturday, May 11, 2002, a 46-year-old coal hauler operator was fatally injured when transporting coal from the face to the feeder in the SouthWest Mains Section. As the operator was attempting to make a right turn into the crosscut between the number four and three entries, the left rear portion of the coal hauler frame pinched the Joy 14 BU loading machine trailing cable between the right inby rib and the coal hauler. This resulted in the frame of the rubber tired coal hauler becoming energized. The victim apparently exited the machine to check the pinch point, came into contact with the energized machine frame and was electrocuted.
