Abstract: In view of the incompatibility of indexes in the comprehensive evaluation of alternatives for mined-out area disposal, the indexes such as safety (safety coefficient), feasibility, cost and required time were combined, by the set pair analysis method, into a relative closeness degree of optimal evaluation sets for describing the comprehensive benefits of mined-out area disposal plans. A scheme with best comprehensive benefit was obtained from five alternatives by the evaluation. It is shown that the result of the evaluation by set pair analysis is well consistent with that by fuzzy optimization method, presenting a new way for the comprehensive evaluation of mined-out area disposal.

Key words: Set pair analysis, Mined-out area disposal, Identical degree, Closeness degree
