摘　　要：针对沙坪煤矿13103工作面复杂地质构造及奥灰水下带压开采的危险情况,分析了无线电坑道透视、瞬变电磁、音频电透等方法的工作原理并使用这些方法进行探测,结合钻孔探查,研究并分析了工作面底板的富水性。研究表明:无线电坑道透视法探测得到的5处异常区域均与工作面掘巷已探明断层、向斜构造相重合;音频电透法与瞬变电磁法均探测出工作面底板富水异常区。结合钻孔探查,分析了异常区具体水文特征。探测结果为制订工作面回采计划提供了有效的地质资料支持,并为相关工作面水文探测提供了新的思路。In view of the complex geological structure of 13103 working face in Shaping Coal Mine and the dangerous situation of Ordovician limestone underwater mining under pressure,the working principles of radio tunnel perspective,transient electromagnetic and audio frequency electrical transmission were analyzed.Combined with borehole exploration,the water richness of the floor in working face was studied and evaluated.The research shows that the five abnormal areas detected by radio tunnel perspective method coincide with the proved faults and syncline structures in the roadway excavation of the working face.Both audio frequency electrical transmission method and transient electromagnetic method have detected the abnormal water-rich area of the floor in working face.Combined with borehole exploration,the specific hydrological characteristics of the abnormal area are analyzed.The detection results provide effective geological data support for coal winning in working face and a new idea for hydrologic detection of relevant working face.
