摘　　要：在详细调查与分析地质构造、水文地质条件和岩溶发育基础上,按照断裂的空间展布规律,划分出江家单斜构造和洞山单斜构造及对应的两个水文地质单元,圈定出江家单斜水文地质单元的灰岩隐伏区为最佳含水地段,再采用物探技术确定最佳含水位置及井点,成井后单井出水量20m3/hr.The best containing water or moisture region was enclosed at the concealed limestone area of the Jiangjia monoclinal hydrogeological unit on the basis of investigation and analysis of geological structure, hydrogeological condition and karst development. The monoclinal structure and hydrogeological units were compartmentalized into Jiangjia and Dongshan, respectively, on the fracture space distributing law. The best containing water or moisture location and well location were confirmed by the geophysical prospecting techniques. The yield of well ranges was 20m3/hr after well completion. 
