- W2355536739 abstract "In order to solve the mining technical problem of outside boundary stay ore for Gu mountain open pit iron ore of Masteel Group,an AHP-TOPSIS comprehensive evaluation index system model was established based on the basic theory of analytic hierarchy process(AHP)and technique for order preference by similarity to ideal solution(TOPSIS), and the AHP-TOPSIS comprehensive evaluation index system model was used to evaluate four kinds of mining methods comprehensively.Considering the economy,technology and security,which impacted the evaluation indexes of mining method,the weight matrix of the evaluation indexes was established according to the AHP method,and then,the AHP-TOPSIS comprehensive evaluation model was established with the basic theory of TOPSIS.Finally,the superior 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 45.3%,46%,64.3%,30%,and the third method is the optimal.The research results are consistent with that of fuzzy mathematics and catastrophe progressing method,and the AHP-TOPSIS comprehensive evaluation model for mining method optimization has the feasibility and effectiveness." @default.
