隐伏矿产勘查是我国现今的主要任务，近几年在内蒙古锡盟地区做了大量的电法测量工作，主要应用大功率激电和可控源音频大地电磁测深方法组合进行找矿，取得了很好的找矿效果。在内蒙古某深部隐伏铅锌矿的勘查中，将大功率激电法用于快速发现和圈定矿区矿化范围及构造展布情况，用可控源音频大地电磁测深法反演电阻率断面图推测地下岩性电性特征、地质结构、构造产状、规模和矿（化）体的赋存空间，为钻探工程提供依据。
隱伏礦產勘查是我國現今的主要任務，近幾年在內矇古錫盟地區做瞭大量的電法測量工作，主要應用大功率激電和可控源音頻大地電磁測深方法組閤進行找礦，取得瞭很好的找礦效果。在內矇古某深部隱伏鉛鋅礦的勘查中，將大功率激電法用于快速髮現和圈定礦區礦化範圍及構造展佈情況，用可控源音頻大地電磁測深法反縯電阻率斷麵圖推測地下巖性電性特徵、地質結構、構造產狀、規模和礦（化）體的賦存空間，為鑽探工程提供依據。

The exploration of deep concealed ore deposits is the main task at present. A lot of electrical measurements have been com-pleted in Xilin Gol League of Inner Mongolia in recent years, which mainly consist of high-power IP and CSAMT or their combinational methods, with good prospecting results achieved. High-power IP measurement was used for discovery and delineation of mineralization limits and distribution of structures in the ore district;Inversion of resistivity of CSAMT section was conducted to deduce underground electrical characteristics of lithology, geological structure, attitude of structure, and size and space of ore ( mineralized) body. The re-sults achieved by the authors provide the basis for the drilling. This paper describes the exploration process of a certain deep concealed lead-zinc deposit in Inner Mongolia and makes interpretation.
