On Jan. 19, 2021, a miner (a haul truck driver with 15y 42w mining experience, 07 42w at this task and mine in Orem, UT with 40 employees*) backed a haul truck to the edge of a dump point that was over steepened by a loader removing material at the bottom of the slope. When the edge of the bank failed, the haul truck traveled backwards and overturned, landing on the roof of the cab. The miner was fatally injured.

Best Practices: 

  • Always dump material in a safe location. If ground conditions aren’t reliable, dump loads a safe distance back and push the material over the edge.
  • Never load material from the toe directly below an active dump point. This may lead to an over steepened and unstable slope.
  • Never drive haul trucks beyond cracks on the top of the dump site.
  • Always construct substantial berms as a visual indicator to prevent overtravel. Clearly mark dump locations with reflectors and/or markers.
  • Always wear a seatbelt.
  • Install advanced systems that restrain miners during roll-overs.
  • Maintain communication between equipment operators and loaders.
  • Train miners to use safe dumping procedures and recognize dumping hazards such as material slides and other unsafe conditions.

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)
