Statistics: Metal Operators

Introduction

The following maps, graphs, and tables represent data for Metal 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.

Metal Operator Occupational Mining Fatalities by Year, 2003-2012Metal Operator Occupational Mining Fatalities by Year, 2003-2012: Graph displaying the number of occupational mining fatalities, excluding office employees, from 2003 through 2012. Rates are not computed when there are a small number of events. The highest number of fatalities over the period was in 2007 when 7 fatalities occurred. There lowest years were 2003 and 2012 when 1 fatality occurred.

Injuries

Nonfatal Lost-time Injuries, 2012 (Metal Mine Operators and Independent Contractors)Nonfatal Lost-time Injuries, 2012 (Metal Mine Operators and Independent Contractors): Map of the United States displaying nonfatal lost-time injury density by county for 885 metal mine operator and contractor injuries during 2012. Office workers are excluded. A graduated color ramp is used to symbolize densities of zero injuries, 1 thru 9, 10 thru 29, 30 thru 49, and 50 or more injuries. 

Number and Rate of Metal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2003-2012Number and Rate of Metal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2003-2012: Chart displaying the number and rate of metal 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 rates and numbers have varied over the period. The highest rate was 4.1 nonfatal lost-time injuries per 100 FTEs in 2003 to a low rate of 2.4 in 2009. The highest number of injuries occurred in 2012 when 194 were reported. The year during the period with the lowest number of injuries was 2009 when 112 injuries occurred. 

Metal Operator Nonfatal Lost-time Injuries by Accident Class for Underground Mining Locations, 2008-2012Metal Operator Nonfatal Lost-time Injuries by Accident Class for Underground Mining Locations, 2008-2012: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for metal operators at underground mining locations for the period from 2008 through 2012. Excluding office employees, there were a total of 793 lost-time injuries. "Handling materials" had 27.5% and "Slip or fall of person" had 20.3% of the nonfatal lost-time injuries. "Machinery" comprised 13.4% and "Fall of ground (from in place)", which 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,” had 13.0% of the nonfatal lost-time injuries. 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. "Powered haulage" had 9.7% and the "All other" category accounted for 16.1% 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.

Number and Rate of Metal Mining Operator Nonfatal Lost-time Injuries at Surface Work Locations by Year, 2003-2012Number and Rate of Metal Mining Operator Nonfatal Lost-time Injuries at Surface Work Locations by Year, 2003-2012: Chart displaying the number and rate of metal mining operator nonfatal lost-time injuries at surface 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 rates and numbers have varied over the period. The rate ranged from a high of 2.2 to a low of 1.5 nonfatal lost-time injuries per 100 FTEs. The highest number of injuries occurred in 2008 when 649 were reported. This was followed in 2009 with 444 nonfatal lost-time injuries reported for a 31.6 percent reduction.

Metal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2008-2012Metal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2008-2012: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for metal operators at surface mining locations for the period from 2008 through 2012. Excluding office employees, there were a total of 2,513 lost-time injuries. "Handling materials" had 34.4%, "Slip or fall of person" had 29.3%, and "Machinery" comprised 10.2% of the nonfatal lost-time injuries. 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. "Powered haulage" had 8.7%, "Hand tools" comprised 8.5%, and the "All other" category accounted for 9.0% 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.
