Data source: publicly released employment and accident/injury/illness data collected by MSHA under 30 CFR 50.
Notes: All analyses of accident data exclude office employees. Occupational fatalities exclude all cases under 17 years of age. Further statistical methodology is available on the NIOSH Internet. Caution should be used when interpreting rates based on a small number of events.
- Mines at which only independent contractors were working did not show any employment and were not counted.
- Average number of employees working at individual mines during calendar quarters of active operations (includes office workers).
- Full-time equivalent employees computed using reported employee hours (2,000 hours = 1 FTE).
- Mining sectors include coal operators, metal operators, nonmetal operators, stone operators, sand and gravel operators, coal contractors, and noncoal contractors.
- Includes actual days away from work and/or days of restricted work activity. For permanently disabling injuries only, statutory days charged by MSHA were used if they exceeded the total lost workdays.
