摘要
为解决灵新煤矿煤层群开采时采空区自然发火,从而影响矿井安全生产的难题,以051601工作面上覆采空区高浓度CO气体治理为例,从CO气体来源分析、高温氧化区判定、治理方案确定以及治理过程等方面,对煤层群开采条件下采空区自然发火防治技术进行了探讨。
In order to prevent goaf spontaneous combustion during coal seams group mining in Lingxin Coal Mine, which affected the coal mine production safety, the authors took the governance of high concentration CO in 051601 working face goal as an example, discussed the goaf spontaneous combustion prevention technology in mining of coal seams group, from CO gas source analysis, high temperature oxidation zone determination, governance plan and governance process, etc.
