中文摘要：

为克服单一物探手段的局限,更准确地预测奥陶系灰岩突水风险,新安煤矿13151工作面采用瞬变电磁、直流电法、槽波地震和无线电波坑透等4种手段进行了综合物探.经比对物探结果,并结合地质与水文地质资料分析,4种物探异常区的重叠区域奥陶系灰岩水向上导升,低阻区条带分布,存在突水危险;煤厚变薄,可能受剪切滑动构造影响;槽波波速1 800 m/s以上,地应力（矿压）集中,利于围岩破坏.多种物探异常区的重叠区域的突水风险最大,是工作面防治水工作的重点.实例证明,综合物探可以弥补单一物探方法之不足,有效指导钻探验证、底板注浆及突水治理工作.

英文摘要：

In order to overcome the limitations of a single geophysical method,and to predict the risk of Ordovician water inrush more accurately,4 geophysical exploration means（transient electromagnetic method（TEM）,DC method,in-seam seismic survey（ISS） and electric-magnetic pit-conveying） were used in 13151 working face in a Xin＇an coal mine.Geophysical exploration results show that the Ordovician limestone water rose up in a low resistivity zone with shortage effective thickness of aquiclude; that the thin seam area could be affected by a shear sliding structure; that the ground stress（mine pressure） concentrated in a high wave velocity area（more than 2300 m/s） in which the surrounding rock was easily destructed.The overlapping region of an abnormal area has a high risk for water inrush,where is the key of water controlling in a mining face.
