大功率双频激电在山东某接替资源勘探区中的应用

我国一大批矿山面临着严重的资源危机,急需开展矿山周边和矿山深部的接替资源勘查工作。大功率双频激电法具有探测深度大、横向分辨率高、抗干扰能力强的特点,在接替资源勘探中有着重要的指示作用。文章以山东某接替资源勘探区为例,讨论了大功率双频激电法的应用效果,并提出了对称四级测深二维反演思路。在大功率激电中梯和对称四级测深相结合的作用下,在接替资源勘探区找到了矿体,说明大功率双频激电法能应用于接替资源勘探。

Exploration for superseding resources based on dual frequeney induced polarization method

A large number of mines in China are facing a serious resource crisis. It is urgent to carry out the exploration of the resources in the periphery of the mine and in the deep part of the mine. The high power dual frequency excitation method has the characteristics of high detection depth, high lateral resolution and strong anti-interference ability, which has important guiding significance in the exploration of replacement resources. Taking an alternate resource exploration area in Shandong as an example, the application effect of the high-power dual frequency induced polarization method is discussed, and a two-dimensional four level sounding inversion method is proposed. The ore body is found in the replacement resource exploration area under the combination of the high power and the symmetrical four level sounding, indicating that the high-power dual frequency excitation method can be applied to the replacement of resource exploration.
