Mining Operations: In 2007, a total of 2,030 coal mining operations reported employment to the Mine Safety and Health Administration (MSHA). Coal mines comprised 13.7% of all mining operations. 1. Bituminous mines comprised 92.4% (n=1,875) and anthracite mines 7.6% (n=155) of coal mining operations. 2. Approximately 72% of all coal mines were located in three states: Kentucky (28.4%), West Virginia (22.6%), and Pennsylvania (20.5%). Employees: A total of 84,071 employees, corresponding to 93,265 full-time equivalent (FTE) employees, were reported by coal mine operators to MSHA. 1. Within the mining sectors, coal operators comprised 27.7% of all employee hours reported. 2. Underground work locations accounted for 45.3% of employee hours, while surface work locations accounted for 54.7%. Fatalities: Twenty-eight (28) occupational fatalities occurred among coal operator employees in 2007, compared to 42 in 2006. 1. Fatalities among coal operator employees accounted for 41.8% of all mining fatalities. 2. The coal operator fatality rate was 31.2 fatalities per 100,000 FTE employees. The underground fatality rate was 42.6 (n=18) compared to a rate of 21.1 (n=10) for surface work locations. Nonfatal Lost-time Injuries: There were 2,942 nonfatal lost-time injuries (2,120 at underground and 822 at surface work locations) among coal operator employees occurring at an overall rate of 3.3 injuries per 100 FTE employees. These injuries resulted in 192,129 days lost from work, comprising 45.1% of days lost across all mining sectors. 1. The underground nonfatal lost-time injury rate was greater than the surface injury rate (5.0 vs. 1.7 per 100 FTE workers). 2. The most frequent classification of nonfatal lost-time injuries for coal operator employees involved handling materials (n=805; 27.4%). 3. Sprains and strains were the most frequently reported nature of injury (n=1,237; 42.0%). 4. The back was the most frequently reported body part injured (n=524; 17.8%) and accounted for 34,799 days lost from work.
