摘　　要：随着我国煤矿开采深度增加,煤层赋存条件愈发复杂。煤层上覆采空区富水情况关系到探放水钻场的布置,甚至对工作面生产带来安全威胁。采用矿井瞬变电磁法,对杉木树煤矿N3032工作面机巷上方顶板区域进行瞬变响应探测,分析上覆采空区富水情况,对工作面探放水钻场布置提供参考依据,同时为工作面的防治水工作提供了真实可靠的地质资料。With the increase of coal mining depth in China,the occurrence conditions of coal seams become more and more complex.The situation of water-rich in the goaf above the coal seam is related to the layout of the exploration and drainage drilling field,and even poses a safety threat to the production of the working face.The mine transient electromagnetic method is used to detect the transient response of the roof area above the machine lane of N3032 working face in Shanmushu coal mine,analyze the water-rich situation of the overlying goaf,provide a reference for the layout of the exploration and drainage drilling field in the working face,and provide a real and reliable geological data for the prevention and control of water in the working face.
