Fire Hazard Analysis at 22301 Fully-mechanized Face in Daliuta Coal Mine

According to the characteristics of 22301 fully-mechanized face of Huojitu Shaft in Daliuta Coal Mine, the fire hazard at this working face was analyzed in two aspects of spontaneous fire and exogenous fire hazards. The results showed that the possibility of spontaneous combustion at 22301 fully-mechanized face was relatively low during mining, and the risk level was controllable. The haulage gate, air return way, starting cut and stopping line of the goaf were the key monitoring areas of spontaneous combustion. The degree of comprehensive mechanization at 22301 fully-mechanized face was relatively high, therefore it existed exogenous fire hazard and it was mainly electromechanical fire.
