Mine Safety and Health Administration Coal Mine Safety and Health Report of Investigation: Underground Coal Mine Fatal Rolling Material October 28, 2007, Mine No. 23 Long Branch Energy Wharton, Boone County, West Virginia ID No. 46-08637

摘要

At approximately 7:45 p.m. on Sunday, October 28, 2007, Charles Jason Keeney, a 34-year old roof bolting machine operator was fatally injured when rocks which had previously fallen from the mine roof, toppled over causing crushing injuries. Approximately 3 weeks prior to the accident, the rocks had fallen from the mine roof and came to rest in a vertical position along the off-side walkway of the Number 4 conveyor belt. The victim was working along the off-side of the conveyor belt, rebuilding cribs and cleaning the walkway. The accident occurred because proper clean-up and support procedures were not established and adequate supervision was not provided to miners who were assigned work duties in a location where rehabilitation work exposed them to hazards associated with fallen roof material.
