摘　　要：以贵州省某矿为例,探明了该矿矿区范围内采空区三带及构造裂隙富水区的空间分布情况。基于电阻率测深法,通过在测区范围内布置了8条探测线,获得了各勘探线成果剖面图。结合测区的地质及水文地质情况、测区的物性特征及各探测线成果剖面图的电阻率分布特征,圈定该矿测区内岩体节理裂隙发育或破碎含水影响范围2个,采空区三带充水或泥影响范围23个,采空区三带未充填或半充填影响范围6个,推断中度水患区9个。根据水文地质调查结果和电阻率测深法勘探剖面成果图对比,证实该矿在测区范围内电阻率测深法探测剖面成果合理可靠,电阻测深法可预报该矿井测区范围内的水文地质特征。Taking a Coal Mine of Guizhou province for example, the spatial distribution situations of three zones and the structural fissure rich water areas in the mined-out area were investigated. Based on the resistivity sounding method, the line probing profile maps were obtained by setting 8 detection lines in testing zone. Combining with geological and hydrogeological conditions and physical characteristics of the testing zone, and the resistivity distribution characteristics of line probing profile maps in the testing zone, some special areas were delineated,including 2 effect areas of rock mass joint fracture or broken water-bearing scope ,23 effect areas of three zones filling with water or mud in mined-out area ,6 effect areas of three zones without being filled or being filled a half in mined-out area and 9 moderate flooding zones. According to contrast between the hydrogeology survey and the exploration profile maps by resistivity sounding method, it is confirmed that the probing profile by resistivity sounding method are reasonable and reliable in the testing zone. So, the resistivity sounding method can be applied to forecast the hydrogeological characteristics in advance in the testing zone.
