| 摘 要： | 目前对电法的探测深度要求越来越高,常规电法有时难以满足实际工作需要。与常规电法相比,可控源音频大地电磁测深法具有探测深度大、设备相对轻便和横向分辨率高等特点,已广泛应用于地热资源、水文地质、有色金属矿产和工程地质勘查工作之中,并取得了令人十分满意的实际应用效果。这里介绍的是一些具有代表性可控源音频大地电磁测深应用实例和应用成果,这些实例基本函概了目前电法的主要应用范畴,常规电法难以胜任的地质调查工作。实例中包括断陷盆地型地热资源和深部基岩裂隙水调查,危机矿山深部找矿和复杂地形条件下铁路隧道工程勘查。

| Abstract: | With the depth increasing of the underground objects to be prospected,the conventional electric methods are difficult to meet the prospecting requirements.Compared with the conventional electric methods,the Controlled source audio-frequency magnetotellurics method is featured of large prospecting depth,portable equipment and high lateral resolution.It has been widely used in geothermal exploration,hydro-geological exploration,non-ferrous mineral exploration and engineering geological investigation,and satisfactory field results have been obtained in these area.However,few papers concerning the application of the method have been published on publicly circulated journals until now,and even fewer are the papers concerning the systematic application of the method.This paper describes some representative field cases and results of the Controlled source audio-frequency magnetotellurics method.These cases basically cover the main application areas of the electric method and the works to which the conventional electric method can not competent,which include fault basin geothermal resource and deep bedrock fracture water prospecting,deep mineral exploration in the near deplete mine,and geotechnical investigation over the complex terrain for railway tunnels. |
