All MSHA-reportable accidents at Eighty Four Mining Company operations in 2011. Fatalities appear first.
The Somerset elevator failed to operate when called by an underground employee. The elevator contractor was called to the mine to repair. There was no damage to the elevator, the repair consisted of a door adjustment. There were no persons injured, or entrapped due to this event.
A supply trip was being hoisted at the Somerset Slope. A pin broke on a drawbar, along with a safety rope which was connected to the trip. This caused the cars to travel back down the slope and de-rail at the bottom. There were no persons injured or equipment damaged as a result of this occurrence. This report is being filed to satisfy the MSHA Inspectors actions.
