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 2013.

Mines

Locations of Active Nonmetal Mining Operations, 2013: United States map displaying the locations of active nonmetal mining operations spotted randomly within counties in 2013. Active mines are mining operations that reported mine operator employment during the year. There were 882 nonmetal mines. Mines at which only contractors were working did not show any employment and are not displayed. 

 

Number of Active Nonmetal Mines by Year, 2004-2013 Graph displaying the number of active mines for a 10-year period from 2004 through 2013. Active mines are those mines that reported any mine operator employee hours during the year. Nonmetal mines have decreased over the period from 741 in 2004 to 641 in 2012. In 2013 the number of active mines was 882. This sharp 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.

 

Locations of Active Underground Nonmetal Mining Operations, 2013: United States map displaying the locations of active underground nonmetal mining operations spotted randomly within counties in 2013. Active mines are mining operations that reported mine operator employment during the year. There were 44 underground nonmetal mines. Mines at which only contractors were working did not show any employment and are not displayed.

 

Locations of Active Surface Nonmetal Mining Operations, 2013: United States map displaying the locations of active surface nonmetal mining operations spotted randomly within counties in 2013.

The employee hours remained steady from 2004 when 46.9 million hours were reported to 46.5 million hours for 2008.  After a decline to 40.8 million hours in 2009, the hours rose to 50.1 million for 2013.

 

Number of Underground Employee Hours Reported by Nonmetal Mine Operators, 2004-2013: Graph displaying the number of underground nonmetal mine operator employee hours reported from 2004 through 2013.

Number of Surface Employee Hours Reported by Nonmetal Mine Operators, 2004-2013: Graph displaying the number of surface nonmetal mine operator employee hours reported from 2004 through 2013. The employee hours remained steady from 2004 when 42.0 million hours were reported to 41.1 million hours for 2008.  After a decline to 35.8 million hours in 2009, the hours rose to 44.5 million for 2013.

 

Fatalities

Nonmetal 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. There were a total of 14 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, 2013 (Nonmetal Mine Operators and Independent Contractors): Map of the United States displaying nonfatal lost-time injury density by county for 398 nonmetal 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 Nonmetal Mining Operator Nonfatal Lost-time Injuries at Underground Work Locations by Year, 2004-2013: Chart displaying the number and rate of nonmetal 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 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.

 

Nonmetal 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 nonmetal operators at underground mining locations for the period from 2009 through 2013. Excluding office employees, there were a total of 317 lost-time injuries. "Handling materials" had 31.9%, "Slip or fall of person" had 23.0%, and "Powered haulage" had 11.7% of the nonfatal lost-time injures. Hand tools accounted for 10.4%, and Machinery had 7.3% 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 7.3% of the nonfatal lost-time injuries. The "All other" category was 8.5% 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, 2004-2013: Chart displaying the number and rate of nonmetal 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 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, 2009-2013: Pie chart displaying the distribution of nonfatal lost-time injuries by accident class for nonmetal operators at surface mining locations for the period from 2009 through 2013. Excluding office employees, there were a total of 1,381 lost-time injuries. "Handling materials" had 42.0% and "Slip or fall of person" had 28.0% of the nonfatal lost-time injuries. "Hand tools" comprised 7.5%, "Powered haulage" had 7.5%, and Machinery comprised 7.1% 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 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.
