Continuous Miner Operator

Fatal injury due to a rib roll while bolting a belt trench at 240 blk 4 to 7 in 9 south.

Texto original en inglés de la MSHA

1. The mine operator's policies and administrative controls did not ensure that the ribs were adequately supported or otherwise controlled to protect persons from the hazards associated with rib rolls while mining out-of-seam.

   Acción correctiva: The approved roof control plan was revised to include rib bolting as mining advanced in out-of-seam areas (18 inches above or below the coal seam) as mining advances to protect miners from rib rolls.

2. Existing equipment was unable to install needed rib support and was thereby unsuited to current conditions. The continuous mining machine was not designed to install rib support. A design change to add rib bolting was not considered when mining out-of-seam or in adverse conditions.

   Acción correctiva: Rib drills were retrofitted to the continuous mining machine to install rib bolts as mining advanced.
