摘　　要：断层是煤矿回采期间煤层顶板水害的主要涌水通道之一,在煤层回采之前,应查清工作面内构造分布情况,槽波地震勘探成为煤矿采前构造探查的重要技术手段。彬长矿区文家坡煤矿4102工作面位于该煤矿41盘区东侧,为41盘区第2个回采工作面,根据巷道掘进期间实际揭露地质资料显示,该工作面断层比较发育,可能影响工作面的正常回采,断层延伸至工作面内长度目前尚未清楚。故利用槽波透射法探测彬长矿区文家坡煤矿工作面断层的发育情况,结果表明此方法效果良好,查明工作面内发育的4条断层基本延展情况,为煤矿防治水害提供一定的科学依据。Fault is one of the main water inrush channels of coal seam roof water damage during coal mining.Before coal mining,the distribution of structures in the working face should be investigated.Therefore,channel wave seismic exploration has become an important technical means for pre-mining structural exploration in coal mines.The 4102 working face of Wenjiapo Coal Mine in Binchang Mining Area is located on the east side of Panel 41 of the coal mine,and is the second mining face of Panel 41.According to the actual geological data revealed during tunnel excavation,the faults in this working face are relatively developed,which may affect the normal mining of the working face.The length of the fault extending into the working face is currently unclear.Therefore,the slot wave transmission method was used to detect the development of faults in the mine working face of Binchang mining area.The results shows that the method is effective,and the basic extension of the four faults developed in the working face is identified,providing a certain scientific basis for the prevention and control of water disasters in coal mines.
