Mining Facts - 2014

Overall Mining

The Mine Safety and Health Administration (MSHA) maintains data collected under the Code of Federal Regulations (30 CFR Part 50) on accidents, fatal and nonfatal injuries, illnesses, employment, and coal production. Summary data were obtained from the MSHA data files for mine operators and independent contractors working on mine property. See Statistical Methodology for further information.

Mining Operations

  • In 2014, a total of 13,604 mining operations [1] reported employment to MSHA.
  • Active mining operations were distributed among the coal (n=1,632; 12.0%), metal and nonmetal (n=1,256; 9.2%), and stone and sand & gravel (n=10,716; 78.8%) industry sectors. [2]
  • The majority of the active mining operations were classified as surface (n=12,900; 94.8%). Underground mines accounted for the remainder of operations (n=704; 5.2%).

Notes

Publicly released employment and accident/injury/illness data were collected by the Mine Safety and Health Administration (MSHA) under the Code of Federal Regulations (30 CFR 50). All analyses of accident data exclude office employees. Occupational fatalities exclude all cases under 17 years of age. Caution should be used when interpreting rates based on a small number of events.

[1] Both mine operator and independent contractor employees work at mining operations. Active mines are those that report any mine o operator employment. Mines at which only independent contractors were working and did not show any operator employment were not counted.

[2] Mining industry sectors include: (1) coal, (2) metal and nonmetal, and (3) stone and sand & gravel.

[3] Average number of employees working at individual mines during calendar quarters of active operations (includes office workers).

[4] Full-time equivalent employees computed using reported employee hours (2,000 hours = 1 FTE; includes office workers).

[5] Independent contractors do not report mine-specific information for employment. The data they provide are summaries for all coal and all noncoal (metal, nonmetal, stone, and sand & gravel) mining operations. For this reason, contractors cannot be included when computing fatality and injury rates for either the metal and nonmetal or the stone and sand & gravel industry sectors.

[6] Mining commodity and type of employer classes include coal operators, metal operators, nonmetal operators, stone operators, sand & gravel operators, coal contractors, and noncoal (metal, nonmetal, stone, and sand & gravel) contractors.

[7] Surface work locations include surface operations at underground mines, surface operations (strip or open pit), dredge, other surface operations, independent shops and yards, and mills or preparation plants.

[8] Total days lost 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.
