Among the many factors affecting the stability of tailings dam, the influence of seepage is very significant. In this paper, the seepage stability of a tailings dam at the accumulation profile elevation and the design elevation were analyzed by using 2D finite element. The results show that the infiltration line will overflow from the dam body when the dam is accumulated at the design elevation. Therefore, two different row seepage measures (traditional drainage and radiation wells) were used respectively to the tailings dam, the seepage stability of the tailings dam by taking two measures were analyzed, the drainage effect of two measures were compared. The results show that the radiation well is better emergency drainage facilities.
