Abstract

Summary The article shows the results of three-dimensional inversion of electrotomographic data obtained on the heap leach ore pile. The main purpose of the study has to identify filtration channels inside the heap, dry ore blocks and leaks through the waterproofing layer. The array of 3-D data was obtained from the 2-D dataset. 3D inversion was performed and sections and electrical resistivity maps were constructed. Anomalies of electrical resistivity associated with two filtration channels were identified. It is shown that low-permeability zones have formed under technological roads, which were detected by anomalies of increased electrical resistivity. They disturb fluids streaming. According to low electrical resistivity local anomalies, the position of leakage sites in the waterproofing layer has detected.
矿石堆的电阻率层析成像
本文介绍了对堆浸矿桩电层析成像数据进行三维反演的结果。研究的主要目的是确定堆内的过滤通道,干燥的矿块和通过防水层的泄漏。三维数据阵列由二维数据集获得。进行了三维反演,构造了剖面和电阻率图。确定了与两个过滤通道相关的电阻率异常。结果表明,在技术道路下形成了低渗透带,通过电阻率异常升高来探测低渗透带。它们会扰乱液体流动。根据低电阻率局部异常,检测出防水层渗漏部位的位置。
