Abstract: In response to the difficulty in deciding the mining blasting scheme of crown and sill pillars, a AHP-TOPSIS comprehensive evaluation index system model has been established based on the basic theory of analytic hierarchy process(AHP)and technique for order preference by similarity to ideal solution( TOPSIS), and the model has been used to do the comprehensive evaluation optimization for 4 kinds of blasting scheme. 9 indexes have been adopted to comprehensively test the impact on the selection element of blasting scheme from the perspective of economy, technology and security, the weight matrix of the evaluation indexes has been established according to the AHP method, and then the AHP-TOPSIS comprehensive evaluation model has been established with the basic theory of TOPSIS. Finally, the superior degrees of blasting scheme has been calculated based on the comprehensive evaluation index. The synthetic superior degrees of the optional blasting scheme are 50.0%, 62.2%, 69.6%, 45.0%, and consequently the third scheme is confirmed the best (hurn cut; inclined hole and side collapse with an angle of 80°). Research results are consistent with the BP neural network, catastrophe progressing method, and Entropy-Fuzzy Matter-element model, which testifies the feasibility of the AHP-TOPSIS comprehensive evaluation model. It provides a new way to select blasting scheme.
