| 摘 要： | 根据大型煤自然发火实验台测得的淮南潘一矿煤样自燃特性参数和2322（3）工作面现场观测数据，得出潘一矿2322（3）综放采空区抽放条件下氧浓度和漏风强度分布规律。通过分析当瓦斯抽放管道进入采空区10m，20m，30m,40m时，采空区内氧浓度和漏风强度动态变化规律，可判断出综放采空区抽放条件下自燃“三带”动态变化趋势，为高瓦斯矿井采空区早期自然发火预测及火灾治理提供依据。

| Abstract: | Based on the spontaneous combustion characteristic parameters using self-ignition experiment oven and the actual observational data of Huainan Panyi mine 2322(3) working face,oxygen concentration and intensity of air leakage can be obtained.By analyzing the dynamic distributing regularityof oxygen concentration and leakage intensity when the gas drainage enters gob 10 m,20 m,30 m,40 m,the dynamic tendency of "Three-Zone" in the gob can be judged,which can provide guidance for early spontaneous combustion prediction and fire prevention of high gas coal mine. |
