Recent Coal Fire at DOE Site In 1992, a DOE site experienced its most recent coal fire initiated by spontaneous combustion. Due to the nature of the fire and initial ineffectiveness of the means utilized to fight it, the fire required more than 28 hours to completely extinguish from the time a hot spot was first detected in the coal bunker.
Six key steps were explored, including coal falling at the coalface, transport, underground bunker storage, main shaft hoisting, coal preparation on the ground, and railway wagon loading. The study resulted in optimized running parameters for the shearers, and the rotating patterns of the shearer drums was altered (one-way cutting was employed).
