The dam failure and leakage risk of tailings dam are directly related to the safe operation of tailings pond, which is an important environmental safety problem. In this paper, the authors used the high density resistivity method to detect the two-dimensional fine section of tailings dam, and found four weak areas of tailings dam structure. Since the leakage is mainly caused by the movement of groundwater, monitoring studies were carried out for three times on the tailings dam before and after the rainy season and, as a result, the dynamic response of the electrical structure of the dam body was obtained, with a suspected dew point determined. The feasibility of application of high density resistivity method to the tailings dam monitoring was verified, and the result provides a new technical means for tailings dam stability study.
