摘要
为防止回采过程中出现自然发火事故,对张集煤矿17258孤岛工作面上风巷埋设束管,利用JSG-7型煤矿束管监测系统采样、检测采空区内气体,划定了采空区"三带",并制定了合理的综合防灭火措施,确保了工作面安全顺利回采。
In order to prevent spontaneous combustion accidents in mining process,buried tube bundle was set in Zhangji 17258 isolated island working face upper hand lane.Using JSG-7 coal mine strap tube monitor system to sample,test gas and delimit ＂three zones＂ in goaf,the paper developed a reasonable comprehensive fire extinguishing measures to ensure the safety mining working smoothly.
