Statistics: Coal Operators

Introduction

The following maps, graphs, and tables represent data for Coal Mne Operators. 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.

Injuries

Nonfatal Lost-time Injuries, 2012 (Coal Mine Operators and Independent Contractors)Nonfatal Lost-time Injuries, 2012 (Coal Mine Operators and Independent Contractors): Map of the United States displaying nonfatal lost-time injury density by county for 2,658 coal mine operator and contractor injuries during 2012.

Number and Rate of Coal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2003-2012Number and Rate of Coal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2003-2012: Chart displaying the number and rate of coal mining operator nonfatal lost-time injuries at underground work locations, excluding office employees, from 2003 through 2012. Full-time equivalent (FTE) employees are based on 2,000 employee hours worked per year. The rate has declined steadily over the period from 6.8 per 100 FTEs in 2003 to 3.4 per 100 FTEs in 2012.

Coal Operator Nonfatal Lost-time Injuries by Accident Class for Underground Mining Locations, 2008-2012Coal Operator Nonfatal Lost-time Injuries by Accident Class for Underground Mining Locations, 2008-2012: Pie chart displaying the distribution of nonfatal lost-time injuries for coal operators by accident class at underground mining locations for the period from 2008 through 2012. Excluding office employees, there were a total of 9,477 lost-time injuries. "Handling materials" had 30.8%, "Slip or fall of person" had 18.8%, and "Fall of ground (from in place)" had 15.5% of the nonfatal lost-time injuries. Note that "Fall of ground (from in place)" includes MSHA’s Accident/Injury/Illness Classifications for “Fall of face, rib, pillar, side, or highwall from in place” and “Fall of roof, back, or brow from in place.” Nonfatal injury 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. "Machinery" accounted for 11.4% and "Powered haulage" had 11.1% of the nonfatal lost-time injuries. "Hand tools" had 5.8% and the "All other" category was 6.6% of the nonfatal lost-time injuries during the 5-year period. Note that the sum of percentages may not equal 100 due to independent rounding.

Full-time equivalent (FTE) employees are based on 2,000 employee hours worked per year. The rate has declined over the period from 2.4 per 100 FTEs in 2003 to 1.3 injuries per 100 FTEs in 2012. The number of injuries has also declined from 989 to 596 over the period. 

Coal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2008-2012Coal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2008-2012: Pie chart displaying the distribution of nonfatal lost-time injuries for coal operators by accident class at surface mining locations for the period from 2008 through 2012. Excluding office employees, there were a total of 3,482 lost-time injuries. "Slip or fall of person" had 36.9%, and "Handling materials" had 26.9% of the nonfatal lost-time injuries. "Powered haulage" had 11.9% of the nonfatal lost-time injuries and "Machinery" accounted for 10.1%. Nonfatal injury 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. "Hand tools" had 6.8% and the "All other" category was 7.5% of the nonfatal lost-time injuries during the 5-year period.
