英文摘要	Although the loop-source TEM near-field survey system has been widely used, this method still cannot meet the demand for large-area 3D data acquisition and fine probing of deep ore bodies. Based on the advantage of near-field survey, a new configuration called short-offset TEM with a grounded wire-source (named SOTEM by authors) has been proposed and the detecting technique has been studied to solve the problem of detecting underground deep ore targets at high resolution. Analysis of the detection capability of this system such as time-domain response as well as investigation depth suggests that the SOTEM has more merits than the long-offset TEM(LOTEM). Apparent resistivity formula suiting for whole field area has been used to calculate apparent resistivity response of geo-electric models in the short-offset TEM system and the results are consistent with that of the designed geo-electric models. The field data have been collected and the results agree with the drilling data. It is concluded that the proposed method is more easily in exploration and has larger detecting depths and higher detection accuracy. It also shows that the SOTEM is a kind of methods worth to be widely applied.
