On September 28, 2022, a miner died when he was engulfed in a collapsed stockpile.  The miner was working close to the toe of the stockpile to remove material off the top of a surge tunnel’s feeder to clear a blockage.

Best Practices: 

  • Operators should have procedures to safely clear blockages from feeders, and train miners to stay out of areas where there is a danger of falling or sliding material.
    • Equip feeders with mechanical clearing devices to prevent exposing miners to hazards of falling or sliding material.
  • Make sure miners trim stockpiles to prevent hazards.

Additional Information: 

This is the 22nd fatality reported in 2022, and the first classified as “Engulfment.”

On January 11, 2022, a 32 year-old miner died while driving on a mine road when a tree fell from a highwall onto the cab of his pickup truck.

Best Practices: 

  • Examine highwalls frequently and from as many perspectives as possible (bottom, sides, and top/crest).  Look for signs of instability such as cracks, sloughing, loose ground, and for fall of material hazards such as large trees and rocks.
  • Train all miners to recognize hazardous highwall conditions.
  • Conduct additional examinations as conditions warrant, especially during periods of changing weather conditions.
  • Clear loose or potentially hazardous material from near the edge of highwalls and slopes, especially when persons will work or travel below.
  • Develop and follow a ground control plan that addresses all potential hazards.

Additional Information: 

This is the third fatality reported in 2022 and the first classified as “Falling, Rolling, or Sliding Rock or Material of Any Kind.”

On October 19, 2021, a 58-year-old mechanic with 17 years of experience was fatally injured when the articulated haul truck bed collapsed on him while he performed maintenance on the truck on the surface at an underground mine Ohio with 10 employees*.

Best Practices: 

  • Securely block from motion machinery or equipment that has been raised, and properly use mechanical blocking devices.  Ensure that blocking material is competent, substantial, and adequate to support and stabilize the load.
  • Position yourself in a safe location and away from potential “red-zone” areas where you can be injured.  Observe and follow all warning labels and signs on equipment.
  • Never work under a load that is unsupported or inadequately supported, and never depend on hydraulics to support a load.
  • Outfit haul trucks with a dump box lock bar that mechanically blocks the bed from coming down.
  • Develop and follow safe work procedures.
  • Always consult and follow the manufacturer’s recommended safe work procedures for the maintenance task.

Additional Information: 

This is the 29th fatality reported in 2021, and the 3rd classified as “Falling, Rolling or Sliding Rock/Material.” (*details added by safeminers.com from MSHA data.)

On September 14, 2021, a 70 year old* individual with no mining experience* was fatally injured at a mine with 3 employees* when an excavated trench collapsed and engulfed him.  The victim was prospecting for gold inside the trench with a metal detector when the trench collapsed.

Best Practices: 

  • Stay clear of potentially unstable areas. Do not enter trenches if the trench walls are not properly supported for the full height or sloped to a safe angle.
  • Do not abandon trenches or excavations without removing the potential of collapse by filling or sloping the walls to a stable angle.
  • Carefully examine ground conditions before performing tasks near excavated embankments, trenches, or ditches.
  • Follow OSHA Trenching and Excavation Safety Guidelines located at https://www.osha.gov/sites/default/files/publications/osha2226.pdf
  • Train miners about the inherent dangers of trenching work.
  • Keep visitors within sight and sound of a responsible person.

On August 18, 2020, a miner (21 year-old laborer in California with one year and twelve weeks of experience*) was killed while attempting to clear a material blockage (at a sand and gravel mine with 20 employees*). The miner entered the cone crusher to begin work when the material shifted and engulfed him.  He was extracted from the crusher and taken to a hospital, where he died the next day.

Best Practices: 

  • Properly design chutes and crushers to prevent blockages. Install a heavy screen (grizzly) to control the size of material and prevent clogging.
  • Equip chutes with mechanical devices such as vibrating shakers or air cannons to loosen blockages, or provide other effective means of handling material, so miners are not exposed to entrapment hazards by falling or sliding material.
  • Establish and discuss policies and procedures for safely clearing crushers.
  • Train miners to recognize and safely remove all potential hazards before beginning work and when clearing blocked crushers.

Additional Information: 

This is the 13th fatality reported in 2020, and the second classified as “Fall of Material.”  – * (Italicized details added by safeminers.com)
