No. 21 Mine explosion
The mine was owned by the Tennessee Consolidated Coal Company and operated by a subsidiary, the Grundy Mining Company.
An U.S. Mine Safety and Health Administration investigation determined that the explosion occurred when a miner's cigarette lighter ignited a pocket of methane gas. Investigators found the mine operator at fault for failing to adequately ventilate the mineshaft, failing to evacuate workers from an area with high methane levels, and failing to effectively enforce regulations that banned smoking materials in mines.
