A miner was trapped inside a bulldozer after the machine fell into a hidden void on top of a coal pile and was engulfed by loose material, according to a safety alert issued by the U.S. Mine Safety and Health Administration (MSHA).
The incident occurred on May 22, 2025, when the bulldozer unknowingly passed over a feeder hole and triggered the collapse. The miner, located inside the cab, was equipped with a “submarine kit,” including high-strength glass, emergency oxygen, and two-way communication. MSHA has not yet released the miner’s condition.
The federal agency noted this is the seventh bulldozer entrapment involving coal stockpiles reported between January 2020 and May 2025.
In response, MSHA urged operators to avoid running equipment directly over feeders, clearly mark draw hole locations, and monitor feed rates for signs of instability. Additional best practices include outfitting equipment cabs with certified high-strength glass, maintaining emergency communication systems, and ensuring all mobile equipment operators are properly trained and belted.
The agency is encouraging the mining industry to adopt feasible new technologies that may reduce the risk of similar incidents.
