In order to solve the mining technical problem of low exploitation in Shengda iron ore, an improved AHP-TOPSIS comprehensive evaluation index system model was established to evaluate five kinds of mining methods. Considering the economy, technology and security, which impact the evaluation indexes of mining method, the weight matrix of the evaluation indexes was established according to the improved AHP method, and then the improved AHP-TOPSIS comprehensive evaluation model was established with the basic theory of TOPSIS. The degrees of mining method based on the comprehensive evaluation index were calculated. The results show that the synthetic superior degrees of the optional mining methods are 29%, 28%, 21%, 22%, 20%, and the first method named piecewise relay retrograded mining filling method is the optimal.
