Statistics: Nonmetal Operators

Introduction

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

Fatalities

Nonmetal Operator Occupational Mining Fatalities by Year, 2003-2012Nonmetal 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. There were a total of 13 fatalities during the period. The highest number of fatalities  was in 2005 when 4 fatalities occurred. No fatalities occurred in 2006, 2010, or 2011.

Injuries

Nonfatal Lost-time Injuries, 2012 (Nonmetal Mine Operators and Independent Contractors)Nonfatal Lost-time Injuries, 2012 (Nonmetal Mine Operators and Independent Contractors): Map of the United States displaying nonfatal lost-time injury density by county for 345 nonmetal 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 Nonmetal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2003-2012Number and Rate of Nonmetal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2003-2012: Chart displaying the number and rate of nonmetal 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 3.7 nonfatal lost-time injuries per 100 FTEs in 2007, to a low rate of 2.3 in 2011. The highest number of injuries occurred in 2008 when 95 were reported. The year during the period with the lowest number of injuries was 2011 when 64 injuries occurred. This was followed by 65 injuries being reported for 2012.

Nonmetal Operator Nonfatal Lost-time Injuries, Underground, by Accident Class, 2006-2010Nonmetal Operator Nonfatal Lost-time Injuries by Accident Class for Underground Mining Locations, 2008-2012Nonmetal 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 nonmetal operators at underground mining locations for the period from 2008 through 2012. Excluding office employees, there were a total of 374 lost-time injuries. "Handling materials" had 29.7%, "Slip or fall of person" had 23.5%, and "Powered haulage" had 12.3% of the nonfatal lost-time injures. Hand tools accounted for 10.7%, and Machinery had 8.0% of the reported lost-time injuries. Note that 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. "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 7.8% of the nonfatal lost-time injuries. The "All other" category was 8.0% 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 Nonmetal Mining Operator Nonfatal Lost-time Injuries at Surface Work Locations by Year, 2003-2012Number and Rate of Nonmetal Mining Operator Nonfatal Lost-time Injuries at Surface Work Locations by Year, 2003-2012: Chart displaying the number and rate of nonmetal 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 with a steady downward trend from 2007 until 2012. The highest rate was 2.6 nonfatal lost-time injuries per 100 FTEs in 2004 to a low rate of 1.5 in 2012. The highest number of injuries occurred in 2004 when 467 were reported. The year during the period with the lowest number of injuries was 2012 when 239 nonfatal lost-time injuries occurred.

Nonmetal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2008-2012Nonmetal 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 nonmetal operators at surface mining locations for the period from 2008 through 2012. Excluding office employees, there were a total of 1,475 lost-time injuries. "Handling materials" had 41.0% and "Slip or fall of person" had 29.5% of the nonfatal lost-time injuries. "Hand tools" comprised 8.0%, "Powered haulage" had 7.3%, and Machinery comprised 7.3% of the nonfatal lost-time injury cases. Note that 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 7.0% 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.
