Abstract: The tailing reservoir has been destroyed in different degrees due to 5.12 Wenchuan earthquake.The status quo of tailings dams, drainage systems and tailings reservoir safety management of Sichuan Hanyuan Jintai Mining Co., Ltd' tailing reservoir was inspected and evaluated, which can provide a basis to determine the security level of the tailing reservoir.Then the high density resistivity method was adopted to detect the structural safety of dam, and analyze the status of the security situation of the tailing reservoir in Jintai mining.Based on the risk assessment and the rapid diagnosis results by high-density resistivity method, the safety technical measures for tailings reservoir were given.

Key words: Earthquake, Tailing reservoir, Stability, High density resistivity method
