摘　　要：为了实现煤矿采掘工作面煤与瓦斯突出超前预警，增强矿井防治煤与瓦斯突出灾害的能力，以赵庄煤矿为研究对象，考察了断层落差对钻屑瓦斯解吸指标K1和钻屑量S的影响，从而推断断层对煤与瓦斯突出的影响并考察了其影响范围：断层落差小于5m时，其影响范围为距断层或尖灭端30m；断层落差为5～15m时，其影响范围为距断层或尖灭端45m；断层落差大于15m时，其影响范围为距断层或尖灭端60m。In order to realize advance early warning of coal and gas outburst in mining and excavation working faces and to enhance the prevention and control capacity of the coal and gas outburst disaster, taking Zhaozhuang Mine as a study object, the paper investigated the fault drop affected to the gas desorption index KJ of drilling cuttings and the drilling cutting value 5, thus inferred affected to the coal and gas outburst and investigated the influence scope. When the fault drop was less than 5 m , the influence scope would be 30 m to the fault or the pinchout end. When the fault drop was 5 - 15 m , the influence scope would be 45 m to the fault or the pinchout end. When the fault drop was over 15 m , the influence scope would be 60 m to the fault or the pinchout end.
