- Sand and gravel mines were the largest mining commodity, comprising 47.8% of all mining operations.
- Sand and gravel mines were found throughout all 50 states and Puerto Rico.
- Minnesota had the largest number of sand and gravel mines (n=488; 6.8%).
- Within the mining sectors,  sand and gravel mine operator employees accounted for 9.8% of all employee hours reported to MSHA.

Nonfatal Lost-time Injuries
There were 550 nonfatal lost-time injuries among sand and gravel operator employees occurring at an overall rate of 1.9 [95% confidence interval (CI): 1.7; 2.1] injuries per 100 FTE employees. A total of 25,912 days lost from work  resulted from these injuries.
- The most frequent classifications of nonfatal lost-time injuries for sand and gravel operator employees involved handling materials (n=196; 35.6%) and slip or fall of person (n=136; 24.7%).
- Sprains and strains were the most frequently reported nature of injury (n=213; 38.7%).

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.
