Dec 31, 1996 A conveyor belt fire in an underground coal mine is a serious threat to life and property. About 30 of the reportable underground coal mine fires from 1988 through 1992 occurred in belt entries. In one instance, a fire started in the drive area of a belt line, spread rapidly, and resulted in seating of the entire mine.
