Abstract: Basis on the deep understanding of the characteristics of caving mining method and backfilling mining method, according to the principle of consistency, testability and scientific, seven evaluation indexes which affect the feasibility of caving mining method converting to backfill mining method were selected, hierarchy evaluation model was constructed. Index weight was calculated through combination weighting approach of subjective and objective evaluation method of analytic hierarchy process and entropy method combination. 

Key words: Caving mining method, Backfill mining method, Analytic hierarchy process, Entropy method, Index weight
