Numerical study on leakage detection of tailings pond by self-potential and DC resistivity methods
Tailings storage is a conventional way of disposal,but tailings leakage seriously threatens the ecological environ-ment.Timely detection of underground leakage is essential for designing efficient remediation strategies.In this paper,we con-ducted a numerical simulation study by the finite-infinite element coupling method,which aimed to explore the feasibility of the integrated geophysical prospecting technology based on DC resistivity and self-potential methods in tailings pond leakage detec-tion.The results show that the two electrical exploration techniques can be combined,verified,and complementary.This com-bination reveals structural anomalies in resistivity and provides information on the location and depth of potential leaks.Our work provides numerical reference and technical scheme guidance for tailings ponds and other leakage problems.
