摘　　要：矿泉水的赋存大多与地下控水构造密切相关,在矿泉水勘查过程中,高密度电法作为众多物探方法的一种,其方法的有效性还有待进一步的验证。为了验证高密度电法在矿泉水勘查中的有效性,通过实地的测网布置,进行高密度外业数据采集、处理、反演和解释。最终圈定了6处矿泉水靶区,圈定的靶区都有一个共性,即在反演解释图上都呈低阻条带状分布,结合地质资料分析推断为断裂破碎带,进一步证明在花岗岩地区矿泉水的赋存和断裂破碎带有密切关系,在6处矿泉水靶区中提供了有效推荐孔位5处,并在推荐孔位进行钻探验证,最终有4处钻孔出水,因此通过高密度电法圈定矿泉水靶区的准确率在80%左右,实践证明高密度电法在矿泉水勘查中是一种十分有效的物探方法,为勘察过程中圈定靶区、钻探定孔提供精准的技术支撑。The occurrence of mineral water is mostly closely related to underground water control structures.In the process of mineral water exploration,high-density electrical method is one of many geophysical methods,and its effectiveness needs to be further verified.In order to verify the effectiveness of high-density electrical method in mineral water exploration,high-density field data acquisition,processing,inversion and interpretation are carried out through field survey network layout.Finally,six mineral water target areas were delineated,and all of them had a common feature,that is,they were distributed in low resistivity bands on the inversion interpretation map,and were inferred as fracture zones based on the analysis of geological data,which further proved that the occurrence of mineral water in the granite area was closely related to the fracture zone.Five effective recommended hole site were provided in the six mineral water target areas,and the recommended hole site were verified by drilling.Finally,four holes were drilled out,Therefore,the accuracy of delineating the mineral water target area by high-density electrical method is about 80%.Practice has proved that high-density electrical method is a very effective geophysical prospecting method in mineral water exploration,providing accurate technical support for delineating the target area and drilling the hole during the exploration process.
