Abstract: In this paper, selection of mining methods is handled as a system engineering problem with multi-objective decision-making．First, in consideration of technical feasibility, economic benefit, resource utilization, labor productivity, safety and environment factors, a comprehensive multi-objective decision-making index system for mining method optimization is built．Then, relatively objective fuzzy weights are assigned by fuzzy judgment matrix after consistency check and adjustment．Finally, an engineering project is conducted concerning filling mining method selection in Jinshandian iron mine．On the basis of primary classification by fuzzy clustering, the sublevel stoping filling method is selected as the optimal mining one by multi-objective fuzzy decision method．

Key words: mining methods, fuzzy judgment matrix, combination weight, multi-objective decision, optimization
