摘要：
Based on the spontaneous combustion characteristic parameters by using the self-ignition experiment oven and actual observational data of Huainan Panyi mine 2322(3) caving face, oxygen concentration and intensity of air leakage can be obtained. By analyzing the dynamic distributing regularity of oxygen concentration and leakage intensity when the gas drainage pipelines enter the gob 10 m, 20 m, 30 m, 40 m, the dynamic tendency of the partition of spontaneous combustion danger zone in the gob can be judged, which can provide guidance for early spontaneous combustion prediction and fire prevention of high gas coal mine.
