"On January 29, 2025, a miner died when a piece of rock fell from the highwall and struck the cab of the drill he was operating.
Best Practices:
Scale highwalls from a safe location to eliminate hazards such as loose, unconsolidated rocks and overhangs.
Conduct highwall examinations prior to working or traveling near the highwall and more frequently as ground conditions warrant, especially after periods of rain, freezing, and thawing.
Examine highwalls from multiple perspectives (bottom, sides, and top/crest) and look for signs of cracking and other geologic features that could lead to instability.
Use auxiliary lighting during low light conditions to conduct highwall examinations and illuminate active work areas.
Ensure miners work, travel, and operate equipment at safe distances from highwalls."
