Abstract: The paper had an analysis on three fire disaster accidents occurred in the fully mechanized top coal caving mining face of seam recovery mining in Hong hui No.1 Mine. With the study and analysis on the function, disadvantages, suitable application conditions and other problems of the air leakage sealing, directly eliminat ion of the combusted material, temperature cooling with water injection, borehole grouting and fire prevention and control with nitrogen injection, the re-spraying-re-grou ting sealing in the goaf of the small mine, the fire zone prediction and forecast with pre-buried tubes, pre-grouting before mining in the blasting weaken zone and other spontaneous combustion prevention measures for the failure zone of the small mine were provided including the control plan of the fire extinguishing gateway, borehole high level grouting, rib and floor spraying for air leakage and coal mining face fire disaster elimination, pre-buried tube for lower level grouting, high level nitrogen injecti on to eliminate the fire disaster in goaf.
