| Abstract: | According to the spontaneous combustion condition of the protected coal pillar in the gateway of No.6205N coal mining face in Danhou Mine under complicated air leakage condition,the paper systematically analyzed the causes of the spontaneous combustion.In combination with the actual condition of the mine,a comprehensive fire prevention and control technology mainly with grouting of fly ash three phase foam,the optimized ventilation system and the water sealing roadway was studied and conducted.The spontaneous combustion of the protected coal pillar was successfully eliminated.A safety mining of No.6205N coal mining face was realized and could provide references experiences to the spontaneous combustion and fire prevention and control of the coal pillar in protected roadway in China coal mine. |
