Coal Fatality – 8/23/22

MINE FATALITY – On August 23, 2022, a contract mechanic received fatal injuries while performing maintenance on the bucket (dipper) of an electric rope shovel.  A plastic block, used to prop open the dipper door, dislodged causing the dipper door to close and pin the victim against the back edge of the dipper.

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.

Additional Information: 

This is the 19th fatality reported in 2022, and the eighth classified as “Machinery.”

Coal Fatality – 8/17/22

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.”

Coal Fatality – 3/20/22

On March 20, 2022, a 33 year-old miner died when he was struck by a roof fall while moving a waterline outby the retreat mining section.  The intersection of the fall area was supported with five-foot fully grouted roof bolts and 10-foot cable bolts.  The roof fall was approximately 40 feet long, 18 feet wide, and five feet thick. 

Best Practices: 

  • Conduct a visual examination of the roof, face, and ribs immediately before any work is started in an area.
  • Be alert to changing roof conditions, especially during retreat mining.
  • Train miners on how to identify hazardous roof and rib conditions.

Additional Information: 

This is the 11th fatality reported in 2022, and the second classified as “Fall of Roof or Back.”
