The primary mineable coal seams in Yanzishan Mine belong to spontaneous combustion seams, the major spontaneous combustion hazard of the roof coal in the roadway and the residual coal in the gob existed, which seriously impacted on the safe production of the mine. For the effective prevention and control of the coal spontaneous combustion, the characteristic parameters of coal spontaneous combustion were tested in the laboratory and the basic law of coal spontaneous combustion was thus mastered. On this basis, the comprehensive fire prevention and extinguishing technology was put forward according to the actual conditions of the mine, the satisfactory effect was achieved, and the spontaneous combustion risk of the roof coal in the roadway and the residual coal in the gob was significantly reduced.
