摘　　要：总结了目前国内主要的物探找水技术方法,分析了各种方法的优缺点及其适应范围。以云南个旧市的找水成果作为典型案例,重点介绍了EH4电磁成像找水方法的技术特点、在岩溶区找水的可行性分析、数据处理和成果解释过程,最后推断出可能存在地下水的位置,并布设井位用于指导施工。后期追踪调查表明,勘察区已成功打出地下水,证明了使用EH4电磁成像技术在岩溶区找水的可行性。To summarize the main geophysical technique which be used to detect groundwater in China at present.Based on the result of detecting water at Gejiu city in Yunnan province,mainly introduce the EH4 system,then analyze the feasibility which using EH4 system to explore groundwater and the course of data processing and explaining.The direction have been offered for drilling by the exploration conclusion.By the later investigating,the water have been found in the survey area.It is proved that the EH4 system is valid on groundwater exploration.
