Because of the limit of land resources, a number of tailings dams constructed by upstream method were-built in valley area of China, Which height reaches 200m. The design, operation and management of high tailings dam is very important for the success of mine production. Taking a 210m high tailings dam as an example, a generalized zoning model of tailings dam is established based on the characteristics of sedimentary tailings in the pond. The stability of high tailings dam is obtained by rigid limit equilibrium method, and the control indexes of tailings dam in different stack heights are analyzed. On this basis, construction method and seepage drainage facilities of the tailings pond are designed and safety-management countermeasures are put forward.
