On October 1, 2021, a 25-year-old Plant Operator with 4 years and 11 weeks experience* was fatally injured at a mine with 3 employees* when he entered a surge bin used as a feed hopper and was engulfed by material.

Best Practices: 

  • Design surge bins and feed hoppers to prevent blockages.  Equip bins and hoppers with mechanical devices or other effective means of handling material, so miners are not required to enter or work inside bins and hoppers.
  • Provide a safe means of access that allows miners to conduct tasks, such as removing large rocks and other material, safely.
  • Ensure handrails and gates are substantially constructed, properly secured, and free of defects.
  • Don’t stand on material stored in bins.  Material stored in a bin can bridge over the hopper outlet, creating a hidden void beneath the material’s surface.
  • Establish policies and procedures to remove blockages in bins and hoppers safely.  Train and ensure miners follow these policies and procedures.
  • Wear an appropriate safety harness, lanyard, and lifeline, and make sure these are maintained, in good condition, and securely anchored.  Assign another miner to constantly monitor and adjust the lifeline, as needed.

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.
