Abstract: Aiming at the problems of short spontaneous combustion period and serious air leakage in goaf in very close distance and easy self-ignition coal seam group in the south of Sichuan province, this paper analyzes the hidden danger of fire preventing and extinguishing work in the period of the working face retracement. Taking Baijiao Coal Mine 2274 working face as an example, this paper analyzes the spontaneous combustion hazard during working face retracement period. Based on the actual geological conditions, the roadway layout and schedule conditions, the integrated fire prevention management system, taking goaf spontaneous combustion prediction mechanism as the basis and taking “high-level grouting in goaf, controlling air leakage, grouting in goaf, spraying retarder at working face” as the core, is proposed.
