On October 7, 2022, a mechanic was fatally injured when he was engulfed in material after he entered an air separator to clear a blockage. 

Best Practices: 

  • Install mechanical flow-enhancing devices, such as mechanical vibratory devices, that can maintain material flow and prevent the need for miners to enter a confined space.
  • Mine operators should establish procedures to clear blockages and train all miners in the procedures.
  • Make sure miners wear a safety belt or harness equipped with a lifeline when entering a confined space, and that a second miner, similarly equipped, is attending the lifeline.

Additional Information: 

This is the 24th fatality reported in 2022, and the first classified as “Confined Space.”

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 September 28, 2022, a miner died when he was engulfed in a collapsed stockpile.  The miner was working close to the toe of the stockpile to remove material off the top of a surge tunnel’s feeder to clear a blockage.

Best Practices: 

  • Operators should have procedures to safely clear blockages from feeders, and train miners to stay out of areas where there is a danger of falling or sliding material.
    • Equip feeders with mechanical clearing devices to prevent exposing miners to hazards of falling or sliding material.
  • Make sure miners trim stockpiles to prevent hazards.

Additional Information: 

This is the 22nd fatality reported in 2022, and the first classified as “Engulfment.”

On September 1, 2022, a roof bolter was electrocuted when he contacted a metal hook that became energized after it penetrated the 480-volt cable that supplied electrical power to a roof bolting machine.

Best Practices: 

  • Make sure miners use suitable, non-conductive ropes when pulling or handling electrical cables. 
  • Never attach conductive parts, such as metallic hooks, to the portions of non-conductive ropes that contact electrical cables.
  • Make sure miners use proper Personal Protective Equipment when handling cables, such as insulated gloves.

Additional Information: 

This is the 20th fatality reported in 2022, and the first classified as “Electrical.”

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.

Additional Information: 

This is the 17th fatality reported in 2022, and the seventh classified as “Machinery.”

Best Practices: 

  • Make sure miners are positioned in a safe location and away from potential pinch point areas.
  • Make sure miners securely block equipment against motion before beginning maintenance or repairs. 
  • Assure blocking material is substantial and installed correctly to support and stabilize the load.
  • Make sure miners conduct repairs according to manufacturer’s recommendations.

MINE FATALITY – On August 17, 2022, a general inside laborer died when he was caught between a supply car and its coupler.  The victim was sitting on the supply car which was coupled to a locomotive parked in a track spur.  The locomotive was struck by another locomotive pulling three loaded cars into the mine.  The impact knocked the victim off the supply car, killing him.

Best Practices: 

  • Assure track switches are in the proper position for your direction of travel and the latches are in contact with the rail.
  • Make sure miners are in a safe location away from equipment parked in a track spur when other equipment is passing along the main rail line.
  • Make sure miners communicate their location and intended movements with the dispatcher.  Repeat the switch alignment back to the dispatcher, where applicable.

Additional Information: 

This is the 18th fatality reported in 2022, and the fourth classified as “Powered Haulage.”
