Abstract: The igneous rock intrusion on S₂905 working face of Daxing Coal Mine is complex, and the fire and gas coupling disasters are serious. Low concentration CO appears in the goaf at the end of mining, which has a great impact on the normal retracement of the working face. The risk of natural fire in goaf during the retracement of working face is analyzed based on the analysis of coal seam spontaneous combustion tendency, fault and igneous intrusion of coal seam into structural belt under the condition of igneous intrusion, the driving speed of working face, the degree of coal body oxidation in the roadway loose ring, and cut-hole spontaneous combustion hazard in the early stage of mining under the influence of gas control. Comprehensive fire-fighting technology and management means, such as strengthening the monitoring and prediction, mainly processing fault and geological tectonic belt of igneous intrusion, strengthening two roadways support and borehole water injection, goaf nitrogen inerting and filling, strengthening extraction from goaf, ensure the safety of working face retracement, perfect the theory and technical system of prevention and control of spontaneous combustion hazard of working face under the condition of igneous rock intrusion in mine.
