Statistics: Metal Operators

Introduction

The following maps, graphs, and tables represent data for Metal Mine 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. Additional Mining Facts for each commodity are available from 2000 through 2013.

Fatalities

Metal Operator Occupational Mining Fatalities by Year, 2004-2013: Graph displaying the number of occupational mining fatalities, excluding office employees, from 2004 through 2013. 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 year was 2012 when 1 fatality occurred.

 

Injuries

Nonfatal Lost-time Injuries, 2013 (Metal Mine Operators and Independent Contractors): Map of the United States displaying nonfatal lost-time injury density by county for 958 metal mine operator and contractor injuries during 2013. 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, 2004-2013: Chart displaying the number and rate of metal mining operator nonfatal lost-time injuries at underground work locations, excluding office employees, from 2004 through 2013. 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 3.7 nonfatal lost-time injuries per 100 FTEs in 2005 to a low rate of 2.4 in 2009 and 2013. 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, 2009-2013: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for metal operators at underground mining locations for the period from 2009 through 2013. Excluding office employees, there were a total of 796 lost-time injuries. "Handling materials" had 29.3% and "Slip or fall of person" had 19.13% of the nonfatal lost-time injuries. "Machinery" comprised 13.6% 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 11.2% 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 10.9% and the "All other" category accounted for 16.0% 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.

 

Number and Rate of Metal Mining Operator Nonfatal Lost-time Injuries at Surface Work Locations by Year, 2004-2013: Chart displaying the number and rate of metal mining operator nonfatal lost-time injuries at surface work locations, excluding office employees, from 2004 through 2013. 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  in 2005 and 2007 to a low of 1.5 nonfatal lost-time injuries per 100 FTEs in 2011 and 2012. The highest number of injuries occurred in 2008 when 649 were reported. The lowest number reported over the period was 428 in 2004.

 

Metal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2009-2013: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for metal operators at surface mining locations for the period from 2009 through 2013. Excluding office employees, there were a total of 2,494 lost-time injuries. "Handling materials" had 35.9% and "Slip or fall of person" had 29.7% of the nonfatal lost-time injuries. "Powered haulage" had 8.5% and "Hand tools" comprised 8.5%. "Machinery" accounted for 8.4% of the nonfatal lost-time injuries during the period. 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.  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.
