Abstract: The comprehensive management of coal mine spontaneous combustion is of great significance for safe mining work. In response to the coal spontaneous combustion accident in the F1301 re mining face of Yunhe Coal Mine, based on the actual situation of F1301 mining face, the hidden dangers of coal spontaneous combustion in the working face are analyzed. Based on the gas sample data from the intake and return air channel drilling, the risk level of coal spontaneous combustion in the goaf on both sides of the working face roadway is divided into three levels: high risk, general risk, and low risk, A fire prevention and monitoring system and comprehensive treatment technology have been proposed and applied in practical engineering. The application results show that the overall CO concentration in each observation borehole shows a fluctuating and decreasing trend, ultimately stabilizing below 24ppm. This effectively suppresses the oxidation process of residual coal in the goaf, eliminates the hidden danger of coal spontaneous combustion in the adjacent 1301 and 1302 goafs during the mining process of F1301 working face, and is conducive to ensuring the smooth subsequent mining of F1301 working face, At the same time, it provides a certain technical reference for the fire prevention and extinguishing design of other similar mines.
