Mining Operations: In 2007, a total of 14,871 mining operations reported employment data to the Mine Safety and Health Administration (MSHA). Almost half (48.4%) were sand and gravel mines, followed by stone mines (31.2%), coal mines (13.7%), nonmetal mines (4.9%), and metal mines (1.9%). Employees: There were 271,414 mine operator employees, or 275,871 full-time equivalent (FTE) workers. For mine operators, 18.9% of the employee hours were for underground work locations, while 81.1% of the employee hours were for surface work locations. Of the 106,709 independent contractor employees (or 60,892 FTE workers), 36.4% were coal contractor employees and 63.6% were noncoal contractor employees. Fatalities: In 2007, there were 67 occupational mining fatalities, compared to 73 in 2006. The overall fatality rate was 21.9 per 100,000 FTE workers. The fatality rate for mine operator employees was 19.7 per 100,000 FTE workers (n=49; 73.1%), while the rate for contractor employees was 31.3 (n=18; 26.9%). Noncoal contractors had the highest fatality rate (33.3), followed by coal operators (31.2), coal contractors (28.0), and metal operators (21.1) per 100,000 FTE workers. The fatality rate at underground work locations was 47.2 per 100,000 FTE workers (n=27; 40.3%) compared to the lower rate at surface locations of 16.1 (n=40; 59.7%). Nonfatal Lost-time Injuries: There were 7,742 nonfatal lost-time injuries reported to MSHA in 2007 (2,645 at underground and 5,097 at surface work locations). These injuries occurred at an overall rate of 2.5 per 100 FTE workers and resulted in a total of 426,219 days lost from work. The underground nonfatal lost-time injury rate was greater than the surface injury rate (4.6 vs. 2.0 per 100 FTE workers). The back continued to be the most frequently reported body part injured, accounting for 1,371 nonfatal lost-time injuries, 77,027 days lost from work, and 18.1% of all days lost. Sprains and strains were the most frequently reported nature of injury (n=3,310; 42.8%).
