摘　　要：张集煤矿17258工作面为孤岛工作面开采,为防止回采过程中出现自然发火事故,采用在上风巷埋设束管,利用JSG-7型煤矿束管监测系统采样、检测采空区内气体,测定出该面采空区"三带"变化规律,确保了17258工作面安全回采。Longwall 17258 of Zhangji Coal Mine is island- like. In order to prevent spontaneous combustion ac- cidents in mining process, bound pipe was pre -settled in air return way to sample gases for type JSG -7 moni- toring system to detect gases in goal, and to determine change of three zones distribution in goal to ensure safety in mining orocess of longwall 17258.
