Statistics: All Mining

Introduction

The following maps, graphs, and tables represent data for All Mining. The information is organized by Mines, Employees, Fatalities, and Injuries. The Mines section contains information on the number and location of the mining operations. The Employees section details the number of employees and the number of employee hours. The Fatalities section describes the number and rate of fatalities, the number and rate by work locations, and the number of fatalities by accident class. The Injuries section presents the number and rate of nonfatal lost-time injuries, the number and rate by work locations, and the number of injuries by accident class. Data source: Mine Safety and Health Administration (MSHA). See Statistical Methodology for further details.

"Machinery" accounted for 11.4% and "Powered haulage" had 11.2% of the nonfatal lost-time injuries. "Hand tools" had 6.1% of the nonfatal lost-time injuries and the "All other" category was 7.0% of the nonfatal lost-time injuries during the 5-year period.

Excluding office employees, there were a total of 18,522 lost-time injuries. "Handling materials" had 34.4%, "Slip or fall of person" had 29.3%, and "Hand tools" accounted for 10.0% of the nonfatal lost-time injuries. "Machinery" accounted as 9.6% of the nonfatal lost-time injury cases. Note that cases classified under machinery were reclassified as a fall of ground (from in place) if the source of the injury was caving rock, ore, etc. This reclassification is consistent with how MSHA classifies similar incidents which resulted in a fatal injury. "Powered haulage" had 8.7% and the "All other" category was 8.0% of the nonfatal lost-time injuries during the 5-year period.
