摘　　要：多功能电法系统是近年来研发的具有我国自主知识产权的地球物理勘探系统,适用于金属矿、地下水、地热、油气藏等资源勘查和研究。选择甘肃柳园地区的花牛山热水沉积型铅锌矿区,开展了多功能电法的应用试验,验证新技术在此类矿床普查评价阶段的有效性。利用大功率激电剖面测量圈定激电异常,并结合已知地质资料进行了评价分析;在有激电异常的主要剖面部署了可控源音频大地电磁测深,获取了地下电性结构。应用结果表明,开展的大功率激电测量和可控源音频大地电磁测深反映出了与矿体有关的地球物理异常,试验应用成果可为同类型矿床的勘查起到示范作用。In recent years,the authors have developed a kind of multifunction electrical system which is a new geophysical technology that has China＇s independent intellectual property rights. The system is suitable for exploration and study of such objects as metal mines,groundwater,geothermal activity and oil-gas reservoirs. In order to verify the effectiveness of the new technique＇s application capability in the hot sedimentary type deposits,the authors have developed IP and CSAMT experiments with this system on the Huaniushan leadzinc deposit in Liuyuan area,Gansu Province. In high-power IP measurement,the authors delineated IP anomaly areas,and carried out evaluation analysis in combination with geological information. In the information section,the authors developed CSAMT method and obtained the underground electrical structure. Application results show that IP and CSAMT can reflect the ore-related geophysical anomaly,and thus can serve as a model for the exploration of the same type of deposits.
