The Evaluation to Quality of Rock Mass Based on Fuzzy Grey Element Theory
Combined with grey system theory, the fuzzy-matter-element analysis is extended to fuzzy grey element analysis. Application of this theory in evaluating the rock mass quality of chamber in mining engineering is actualized in this paper, and the quantitative results of the evaluation arranged by fine-bad sequence are given by the calculation of dependent degree and dispose of membership degree. Whats more, the weights of the indexes in evaluation are analyzed by information entropy theory integrates with summation normalization method, so that subjective factors in the evaluation can be effectively avoided. The quantitative results show efficacious and feasible of the evaluation by fuzzy grey element theory.
