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. Additional Mining Facts for each commodity are available from 2000 through 2014.

Mines

thumbnailLocations of Active Nonmetal Mining Operations, 2014: United States map displaying the locations of active nonmetal mining operations spotted randomly within counties in 2014. Active mines are mining operations that reported mine operator employment during the year. There were 911 nonmetal mines. Mines at which only contractors were working did not show any employment and are not displayed. 

 

thumbnailNumber of Active Nonmetal Mines by Year, 2005-2014 Graph displaying the number of active mines for a 10-year period from 2005 through 2014. Active mines are those mines that reported any mine operator employee hours during the year. Nonmetal mines have decreased over the period from 739 in 2005 to 641 in 2012.  In 2013 and 2014, the number of nonmetal mines increased to 882 and 911, respectively. This  increase may be attributed to the new Standard Industrial Classification (SIC) added by MSHA for "Sand, industrial; ground silica/quartz" (SIC=14460) with a canvass class of nonmetal. Prior to 2013, these mines were assigned to "Sand & gravel" (SIC=14410) with a canvass class of sand & gravel.

Fatalities

thumbnailNonmetal Operator Occupational Mining Fatalities by Year, 2005-2014: Graph displaying the number of occupational mining fatalities, excluding office employees, from 2005 through 2014. Rates are not computed when there are a small number of events. There were a total of 18 fatalities during the period. The highest number of fatalities was in 2014 when 5 fatalities occurred. No fatalities occurred in 2006, 2010, or 2011.

 

Injuries

thumbnailNonfatal Lost-time Injuries, 2014 (Nonmetal Mine Operators and Independent Contractors): Map of the United States displaying nonfatal lost-time injury density by county for 426 nonmetal mine operator and contractor injuries during 2014. 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. 

 

thumbnailNumber and Rate of Nonmetal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2005-2014: Chart displaying the number and rate of nonmetal mining operator nonfatal lost-time injuries at underground work locations, excluding office employees, from 2005 through 2014. 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 1.3 in 2013. The highest number of injuries occurred in 2008 when 95 were reported. The year during the period with the lowest number of injuries was 2013 when 38 injuries occurred.

 

thumbnailNonmetal Operator Nonfatal Lost-time Injuries by Accident Class for Underground Mining Locations, 2010-2014: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for nonmetal operators at underground mining locations for the period from 2010 through 2014. Excluding office employees, there were a total of 283 lost-time injuries. "Handling materials" had 30.7%, "Slip or fall of person" had 23.0%, and "Powered haulage" had 12.4% of the nonfatal lost-time injures. Hand tools accounted for 9.9%, and Machinery had 8.5% 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 7.4% of the nonfatal lost-time injuries. The "All other" category was 8.1% 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.

 

thumbnailNumber and Rate of Nonmetal Mining Operator Nonfatal Lost-time Injuries at Surface Work Locations by Year, 2005-2014: Chart displaying the number and rate of nonmetal mining operator nonfatal lost-time injuries at surface work locations, excluding office employees, from 2005 through 2014. 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 2.4 nonfatal lost-time injuries per 100 FTEs in 2005, 2007, and 2008 each.  The lowest rate was 1.5 in 2012. The highest number of injuries occurred in 2005 when 429 were reported. The year during the period with the lowest number of injuries was 2012 when 239 nonfatal lost-time injuries occurred.

 

thumbnailNonmetal Operator Nonfatal Lost-time Injuries by Accident Class for Surface Mining Locations, 2010-2014: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for nonmetal operators at surface mining locations for the period from 2010 through 2014. Excluding office employees, there were a total of 1,412 lost-time injuries. "Handling materials" had 41.7% and "Slip or fall of person" had 27.5% of the nonfatal lost-time injuries. "Powered haulage" had 8.1% 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. "Hand tools" comprised 7.2% and the "All other" category accounted for 8.1% 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.
