On February 26, 2023, a contract miner died while operating a bulldozer. The bulldozer traveled over the edge of an access road and rolled feet down an embankment, ejecting the miner from the operator’s cab. The miner was not wearing a seatbelt.

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.

Additional Information

This is the ninth fatality reported in 2023, and the second classified as “Machinery”.

On April 9, 2023, a miner died while mounting off road truck tires on rims.  The miner was in the process of mounting a tire on its rim when another tire’s outer lock ring dislodged, became airborne and struck the victim in the head.

Best Practices

  • Use a tire safety cage (or other tire restraint device) when inflating a truck tire that is not on the truck.  Stand away from the inflating tire and out of the wheel and air blast trajectory during the inflation process.
  • Check tires and rims for damage and defects before performing work.
  • Before repairing tires, completely deflate the tires by removing the valve core and checking the valve stem to make sure it’s clear. 
  • Follow the manufacturer’s procedures and make sure tire and rim components are compatible.
  • Train miners who service tire and rim components. 

Additional Information

This is the 15th fatality reported in 2023, and the fifth classified as “Machinery.”

On March 15, 2023, a miner drowned when the ground sloughed causing the excavator he was operating to topple into a water-filled pit.  The excavator became submerged in approximately 25 feet of water.

Best Practices

Mine operators should:
•    Install berms at the edge of the working surface so machinery can operate a safe distance from the water.
•    Evaluate ground conditions and mining methods before operating equipment near water.
•    Examine work areas and equipment and correct unsafe conditions.
•    Task train equipment operators on the operation of machinery.

Additional Information

This is the 12th fatality reported in 2023, and the fourth classified as “Machinery.”

On October 1, 2022, a miner died while using a crane to remove a haul truck engine.  The auxiliary line broke, causing the hook and ball assembly to fall and strike the miner.

Best Practices: 

  • Make sure cranes have functional anti-two blocking devices to automatically shut off the crane when the rigging on the hoist line gets close to the sheave at the end of the crane boom.
  • Make sure miners stay clear of suspended loads and use taglines when necessary for steadying or guiding suspended loads.
  • Make sure miners conduct thorough pre-operational inspections of all machinery, equipment, and tools prior to use.

Additional Information: 

This is the 23rd fatality reported in 2022, and the eighth classified as “Machinery.”

On August 4, 2022, a mine manager died while performing maintenance on a bulldozer.  While kneeling on the bulldozer’s track, the victim accidentally engaged the lever that put the bulldozer in reverse.  The bulldozer track moved the victim to the rear of the bulldozer where he was run over.

Best Practices: 

  • Operators should train miners on safe maintenance procedures:
    • turn off the engine
    • block equipment against motion
  • Operators should make sure miners are in a safe location in relation to machine parts that can move.
