March 1, 1996-- A roof bolter operator was helping repair a broken conveyor belt on a belt drive. He reached over the structure to assist in feeding the belt through the tandem drive roller when he was drawn into the drive rollers resulting in fatal injuries. The accident occurred because the employee used a dangerous pro cedure to thread the conveyor belt through the belt drive.

April 12, 1996-- Three miners were removing equipment from the mine. A foreman and a utility man, riding in a rubbertired batterypowered personnel carrier, arrived near where a roof bolting machine was located. The personnel carrier was parked about 32 feet uphill from the roof bolting machine. The two miners left the personnel carrier and traveled downhill, past the roof bolting machine operator standing at the rear bumper of the machine, and were beside the machine when they heard a noise behind them. The personnel carrier had rolled down the 16 percent grade, crushing the roof bolting machine operator against the roof bolting machine, causing fatal injuries.

November 20, 1996 -- A working section was engaged in retreat mining when a coal bump/outburst occurred. The accident resulted in fatalities to two roof bolters, and four additional miners were injured.
