Roof Bolter

Employee had finished bolting a section of mine roof at approximately 10:30 am and was preparing to move the roof bolter out of the #1 entry when he was handed a wrench he had requested earlier. He walked up the side of the bolter to place the wrench in his tray when a piece of rock fell without warning, striking him.

Texto original en inglés de la MSHA

1. Management oversight of adverse roof conditions was not adequate. A change in mining height created a brow at the location of the fatal accident. Roof bolt spacing was too wide at the area of the brow and adequate supplemental supports were not installed.

2. The Approved Roof Control Plan was not complied with in that management failed to evaluate adequately the changing geological conditions and continued mining a 25-foot depth cut.
