The safety status of tailings is related to the lives and properties of downstream residents and the work safety of mine,and its safe operation is imperative. Therefore,the dynamic evolution characteristics and safety about stability of tailings dam during the production should be grasped and known in real-time. In this paper,aiming at the shortcomings of the existing evaluation methods,based on detailed evaluation theory in slope stability evaluation,combining with the characteristics of tailings dam,basal and dam construction,a detailed evaluation method of tailing dam was established. Combing with special engineering project,the evaluation results were compared and analyzed with that of traditional method. It showed that the result of detailed evaluation method has the characteristics of higher reliability and high precision,which is closer to the true value in stable state. It provides a decisionmaking basis for safety evaluation and design of tailings dam.
