Electrical accidents occurring in coal mines from 1975 through 1979 were categorized and analyzed. The data were searched for common electrical hazards, common activities by those injured, and common negligent or careless behavior. The accident data were combined with mine production statistics to form a normalized electrical accident rate. It was found that some mines have consistently more lost workdays per work-hour than other mines. Bureau of Mines electrical safety research contracts were reviewed to determine whether the research effort was directed toward those areas that are related to the most accidents; in some cases it was not. A method was devised and utilized to estimate the relative cost to the mining industry to implement certain safety measures developed through Bureau research and the potential safety benefits. MSHA regulations were reviewed for effectiveness in preventing electrical accidents and suggestions were made for discontinuing, clarifying, or otherwise modifying the regulations.
