| Abstract: | In the 5306 working face of Tangkou Coal Mine,during the stoping and withdrawal of the working face,it is very easy to have the spontaneous combustion of the remaining coal in the goaf,and the conventional fire prevention cost is high.Therefore,the compound inert gas is proposed to be used for the prevention and control of the remaining coal in the goaf.The results show that the spontaneous combustion of coal in goaf is effectively prevented and the cost of fire prevention is greatly reduced. |

| Keywords: | compound inert gas spontaneous combustion of residual coal stop mining fire prevention and extinguishmen |
