Abstract: It will cause serious contamination to surroundings if the polluted solid and liquid wastes piled up in tailings pond are not properly treated. To determine the stability of tailings pond and analyze the influence of solid and liquid wastes on the surrounding soil and groundwater, it is urgent to find out the morphological characteristics and storage capacity scale of tailings pond. As a conventional geophysical prospecting method, high-density resistivity technique is simple, rapid and effective, and has become the preferred option of on-site detection in determining the morphological characteristics of tailing ponds. In this study, the range of bottom interface of tailings pond is obtained by inversion of high-density resistivity method. Combined with drilling verification, the 3D visualization model of tailings pond is built on Voxler platform for more accurate calculation of volume of tailing sand, which proves the feasibility of high-density resistivity method in determining the morphological characteristics of tailings pond.
