Objective: To explore factors associated with fatal accidents among contractors and operators by using the Mine Safety and Health Administration database. Methods: Cross-sectional data on 157,410 miners employed by operators or contractors during 1998-2007 were analyzed using logistic regression and multiple imputation. Results: Univariate odds of fatal versus nonfatal accident were 2.8 (95% confidence interval, 2.3 to 3.4) times higher for contractors than operators. In a multivariable model, fatality was associated with contractor, less experience at the current mine, and occurrence at more than 8 hours into the workday (P < 0.05 for each). Differences in odds of fatality by employment type were more pronounced in surface mines. Conclusions: Contractors had a higher proportion of fatal injuries. Fatality also varied by mine experience, the number of hours worked before injury, work location, and mine type.
