renewcomerLeave a comment

On June 7, 2021, at a mine with 25 employees*, a 56 year old hopper operator with 6 years and 36 weeks experience* entered the top of a primary feed hopper to break up and remove a large rock. Raw material that remained on the sides of the hopper sloughed off and engulfed the miner.

Best Practices: 

  • Equip hoppers with mechanical devices, grates/grizzlies or other effective means of handling material so miners are not required to enter or work where they are exposed to entrapment by caving or sliding material.
  • Establish and assure policies and procedures are followed to safely remove blockages in bins and hoppers. Follow manufacturer recommendations.
  • Provide a safe means of access that allows miners to safely conduct tasks such as removing large rocks and other material.
  • Wear an appropriate safety harness, lanyard and lifeline which are securely anchored and constantly monitored and adjusted by another person, as needed, prior to entering bins or hoppers.
  • Train miners in safe work procedures and hazard recognition especially when removing blockages in bins or hoppers.

On May 18, 2021, a telehandler at an underground mine with 113 employees and 7 contract employees* was towing a trailer with a diesel pump onboard up an inclined underground roadway when the tow hitch suddenly broke. The trailer rolled down the roadway, striking and fatally injuring a 35 year old* contract laborer with 1 year experience*.

Best Practices: 

  • Use towing hardware (hitches, tow bars, receivers, couplers, pins, pintles, safety chains/cables, etc.) which is properly designed and rated. Before each use, examine towing hardware for wear, cracks and other damage. 
  • Never exceed the recommended maximum towing capacity of a tow vehicle or trailer. Follow the manufacturer’s recommendations and only use equipment designed for towing.
  • Always use properly sized safety chains in conjunction with hitches. Safety chains keep the trailer connected to the tow vehicle in case the other tow hardware fails.
  • Never position yourself directly behind equipment being towed uphill.
  • Establish procedures for safe and proper towing. Train miners to follow these procedures and identify hazards associated with towing.

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.
