[Abstract]:During the withdrawal of hydraulic support in 72205 face of Sanhejian Coal Mine, the CO concentration in the working face and the return air roadway was seriously exceeded. According to the geological conditions of surrounding rock of the working face, the causes of spontaneous combustion were analyzed, and the process of spontaneous combustion was expounded. Under the condition that the effect of conventional fire prevention and fire extinguishing method is not satisfactory, the fire zone is extinguished quickly and successfully by using the new technology of fire prevention and fire extinguishing by Prette.
