Regarding characteristics of tailings pond and the requirements of regulations in China, a quantitative evaluation framework of tailings pond indicators was founded. The index system for tailings pond was divided into four parts, which were management capability, engineering designing, monitoring indexes and environmental impact. Furthermore, a set-pair analysis (SPA) based on fuzzy assessment method (Fuzzy-SPA) was presented for the quantitative risk assessment in this paper. It overcame some defects in traditional risk assessment methods and expanded the scope of current methods. Both qualitative and quantitative indexes can be used in the method, then a comprehensive risk score can be achieved. The proposed model was applied to assess a certain tailings pond in Benxi. The result indicated that this method used was feasible and rational. The work presented in this paper can be as reference through adequate selection of model parameters to the safety assessment work for the tailings ponds.
