摘要

On Friday, October 28, 2011, at approximately 6:15 a.m., 47-year old Darrel Alan Winstead, Certified Blaster, and 23-year old Samual Joe Lindsey, Blaster Helper, were killed when the 1-ton truck they were in was struck and covered by rock and rubble when a portion of the highwall failed. Both miners were employees of Mine Equipment and Mill Supply Company (MEMSCO), a contractor blasting company for Armstrong Coal Company, Inc. The two miners were in the no. 11 Pit traveling to the area of the pit that had been prepared for the loading of explosives and the eventual blasting of material as part of normal mining activity when the highwall failure occurred. The accident occurred because mine management failed to recognize a geologic anomaly, located in the portion of the highwall below the no. 14 coal seam and above the No. 13 coal seam, prior to the highwall failure.
