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.”
