【摘要】：基于浅埋藏煤层采空区受地表裂隙诱导漏风的影响,从采空区煤自燃防治为出发点,以磁窑沟煤矿10_(-2)号煤层10202工作面为研究对象,通过采空区铺设束管观测系统,辅助测点的氧气浓度变化,分析了浅埋藏工作面采空区氧气浓度变化规律,得到了采空区自燃氧化区域的分布特征。通过采空区自燃氧化三带的实测分析,掌握了磁窑沟浅埋藏工作面自燃氧化区域分布及最低推进速度,有助于指导矿井的防灭火实践。
[Abstract]:Based on the influence of air leakage induced by surface fissures in the goaf of shallow buried coal seam, starting from the prevention and control of spontaneous combustion of coal in goaf, taking the No. 10 coal seam 10202 face of Ciyaogou coal mine as the research object, the observation system of beam tube is laid in the goaf. The variation of oxygen concentration in the goaf of shallow buried working face is analyzed, and the distribution characteristics of spontaneous combustion oxidation zone in goaf are obtained. Through the measured analysis of the third zone of spontaneous combustion oxidation in goaf, the variation of oxygen concentration in the goaf is analyzed. The paper grasps the distribution of spontaneous combustion oxidation zone and the lowest speed of propulsion in shallow buried face of magnetic kiln ditch, which is helpful to guide the practice of preventing and extinguishing fire in mines.
