Abstract: The spontaneous combustion phenomenon in Gongquan 3^# coal seam is serious due to the short period of spontaneous combustion and average interval of only 1.4 m to 2.4 m with the overlying 2^# seam. The 2273 working face, under the impact of air distribution, roadway support, mining and advancing and other aspects, faces the typical spontaneous combustion prevention problem in flammable seam group during recovery period. By establishing advanced monitoring, advanced prevention, emergency treatment and other governance mechanisms for spontaneous combustion, the face, taking multiple technical means including strengthening the quality of roadway support, blocking leakage channel, preventive grouting, preventive nitrogen injection, priming liquid carbon dioxide, successfully disposes of serious self-ignition accidents of overlying 2272 old mined out area and ensures the safety of mining face.
