Mine Safety and Health Administration Coal Mine Safety and Health Report of Investigation: Underground Coal Mine Fatal Fall of Roof Accident September 3, 2007. Bronzite Mine Consol of Kentucky, Inc Williamson, Mingo County, West Virginia MSHA I.D. No. 46

摘要

At approximately 4:55 p.m. on Monday, September 3, 2007, Brent Reynolds, a 35- year old continuous mining machine operator, was fatally injured when a portion of the mine roof collapsed. The accident occurred after one shuttle car had been loaded from the face of the No. 4 entry, and the victim and the section foreman, knelt in the intersection, behind the third and fourth rows of permanent roof supports. As the two miners were talking, a large portion of mine roof fell without warning, resulting in fatal injuries to Reynolds. The accident occurred because adverse roof conditions, comprised of interbedded shale and siltstone, with slickensided claystone, overlain by a 4-inch thick rider seam, exceeded or nearly exceeded the length of the 4-foot roof bolt used as primary roof support. Although the rider seam was detected during roof bolting activities which took place during rehabilitation of the area, adequate roof control measures were not taken.
