摘要
葛亭煤矿2313老采空区气体波动频繁,并且有害气体不断向外泄露。通过气体分析、气压观测以及示踪气体检测漏风等手段,确定了采空区气体变化的影响因素。在制定和实施采空区封闭堵漏风措施时,研究建立了"氮气均压气室",并应用无机塑性材料对于密闭周边裂隙进行充注,提高了采空区的气密性,保持了采空区的惰化状态。
The gas fluctuates frequently in the old goaf 2313 of Geting Coal Mine, and the harmful gas leaks out continuously, Througn the gas analysis, gas pressure observations and tracer gas leakage detection, the influence factors of gas change in goaf are determined. During the formulation and implementation of goal closed air leakage blocking measures, the ＂nitrogen pressure equalization chamber＂ has been established, and the inorganic plastic material is used to fill the closed fractures around, which improves the air tightness of goaf, and keep the inerting state of goaf.
