Abstract. A conveyor belt fire presents a serious safety hazard in an underground coal mine. A review of underground coal mine fires involving conveyor belts which occurred within the past two decades was made by the Mine Safety and Health Administration (MSHA). Belt fires that occurred during this period of time have burned as much as 610 m of belting before the fire was …
