On February 28, 2025, a miner died when a piece of rock fell from an unsupported pillar rib and struck him.

Best Practices

  • Be aware of potential hazards when working or traveling near mine ribs with rock and partings.  Rock in the rib has been associated with over 80% of rib fall fatalities in the past decade.
  • Conduct thorough pre-shift and on-shift examinations of the roof, face, and ribs and conduct examinations thereafter as conditions warrant.  Scale loose ribs as necessary.
  • Rib support may be necessary when the mining height increases, when rock is present in the rib, or when encountering deeper cover.
  • For the best protection against rib falls, install rib bolts with adequate surface control products during the mining cycle and in a consistent pattern.
  • Train miners to recognize roof and rib hazards and to stop work in the area until the hazards are corrected.

Additional Information

This is the eighth fatality reported in 2025, and the second classified as “Fall of Face, Rib, Side or Highwall.”

On January 10, 2025, a mobile bridge carrier pinned the operator against the coal rib, causing fatal injuries.

Best Practices

  • Stay out of pinch points and “Red Zone” areas.
  • Install and maintain person-in-position switches on mobile bridge carriers to require the miner to stay in the operator’s compartment while in motion.
  • Stay in the operator’s compartment when operating equipment.
  • Activate the emergency de-energization device or “panic bar” before exiting the operator’s compartment in the event of a hazardous situation.
  • Communicate your presence and intended movements when working around mobile equipment and wait for acknowledgment before moving. 

Additional Information

This is the second fatality reported in 2025, and the first classified as “Powered Haulage.”
