Abstract In view of the difficulty of decision-making in the scheme selection of a bauxite mine in extensive section blasting, it is combined with analytic network process (ANP), fuzzy theory, and TOPSIS theory. The establishment of ANP-Fuzzy-TOPSIS comprehensive evaluation index system of comprehensive evaluation model can optimize the 3 selections of blasting scheme. From the 10 indicators of careful consideration of the impact of blasting scheme selection factors of 3 aspects of economy, technology, and safety, through the analytic hierarchy process, it objectively determines the weight vector of each evaluation index. Then, combined with the theory of fuzzy mathematics and the ideal construction of ANP-Fuzzy-TOPSIS comprehensive evaluation model solution method principle, the comprehensive evaluation index of each scheme calculate is calculated based on the superior degree. The selected cutting scheme is superior to 49.8%, 51.3%, and 48.4% to determine the second kinds of blasting scheme (double wedge cut) optimal. The results of this study are consistent with the results of BP neural network method, catastrophe progression method, and AHP-TOPSIS model, which prove the feasibility of the model. Keywords Cut scheme . Evaluation index . Analytic network process (ANP) . Fuzzy theory . Technique for order preference by similarity to ideal solution (TOPSIS) . Comprehensive evaluation model
Introduction Traditional large-section excavation blasting often adopts the method of split blasting, which has the problems of low efficiency, high cost, and poor safety of work (Zhigang and Wenzhao 2014). With the recent advancement of excavation equipment and advances in blasting technology, more and more mines have chosen to use a blasting method in largesection excavation (Wang 2009). When blasting, the design and optimization of the gutter scheme is a critical link in the blasting process. The rationality of the gutter process and

parameters is the efficiency and cost of the blasting effect and the subsequent mining, shovel loading, transportation, and crushing operations. There is a direct impact (Shihai et al. 2007) and choosing the appropriate blasting and boring scheme is an important measure to ensure safe excavation, efficient tunneling, improve tunneling efficiency, and meet the overall production schedule of the mine. In a bauxite mine, a large-section excavation is carried out by means of one blasting during the mining operation. However
