On June 22, 2023, a contract bulldozer operator died when the bulldozer he was operating backed off the edge of a highwall.  The bulldozer operator was clearing the bench in preparation for drilling and blasting and had removed the berms along the edge.

Best Practices

  • Install berms, signs, or devices to identify the edge of benches.
  • Perform workplace examinations and correct hazardous conditions before beginning work and as ground conditions warrant. 
  • Train equipment operators to identify dangerous conditions and to keep the bulldozer blade between them and the edge near drop-offs.

On June 8, 2023, a miner died after climbing over the handrail onto a conveyor belt to gain access to a magnet belt that needed adjustment. When the miner stepped onto the magnet belt, the belt started, throwing the miner 16 feet to the ground below.

Best Practices

• De-energize, lock-out, tag-out, and block machinery against motion before performing repairs or maintenance on a belt conveyor.
• Install a system which provides visible or audible warning to warn miners that the conveyor will be started.
• Provide and maintain safe access to all workplaces and establish safe work procedures.
• Use fall protection when a fall hazard exists. Ensure fall protection has a suitable fall arrest and secure anchorage system, and that miners are properly trained.

Additional Information

This is the 22nd fatality reported in 2023, and the second classified as “Slip or Fall of Person.”

On May 22, 2023, a miner died when the haul truck he was operating overturned, when the edge of the bank at a dump point gave way.  The haul truck landed on the roof of the cab. 

Best Practices

  • Conduct workplace and ground condition examinations before work begins in an area.
  • Dump material from a safe location and push the material over the edge with a bulldozer.
  • Ensure dump locations on unconsolidated material are properly designed, constructed, and maintained.   
  • Construct substantial berms as a visual indicator to prevent overtravel.  Clearly mark dump locations with reflectors and/or markers.
  • Never load material from the toe of a stockpile that is directly below an active dump point.  This may lead to an over steepened and unstable slope.
  • Wear a seatbelt.  Install advanced systems that restrain miners during roll-overs.

Additional Information

This is the 20th fatality reported in 2023, and the fifth classified as “Powered Haulage.”

Best Practices

  • Always wear a seatbelt when operating mobile equipment. Monitor work activities routinely to ensure miners wear seatbelts and follow safe work procedures.
  • Examine ground conditions before beginning work and remain alert as conditions change throughout the shift.
  • Train miners on the equipment they operate, including safe work procedures, and to identify and report hazards.
  • Always be aware of your position relative to roadway edges and benches.

Best Practices

  • Establish and follow ground control plans that are consistent with prudent engineering design for the safe control of all highwalls, pits, and spoil banks.  
  • Examine highwalls, spoil banks, and ground that slope into working areas after every rain, freeze, or thaw before work in such areas.
  • Stay clear of potentially unstable areas.  Correct unsafe ground conditions in the affected area.
  • Equip bulldozers with two-way communication systems, high strength glass, and an SCSR for breathable air when working on material that has the potential to slide or engulf mobile equipment.
