摘要
在多采空区条件下,各采空区之间存在漏风通道,存在查找分析CO的来源困难的问题,通过打钻取气化验,释放SF6查找漏风通道,建立了多采空区条件下查找CO来源的方法,采取了注氮和注浆封堵措施,有效地抑制了相邻采空区有害气体的扩散。
Because of air - leaking channels existing between each goaf, there is a difficult problem to find the source of CO under the condition of multi - goaf. Through drilling borehole to take and test gas, releasing SF6 to find air - leaking channels, the paper proposes a method to find CO gas source under the condition of multi - goal, taking nitrogen injection and grouting sealing measures can ef- fectively inhibit toxic gas dispersion in adjacent goal.
