Comprehensive Evaluation Of The Stability Of Coal Mining Subsidence Based On Fuzzy Matter-Element Theory

Established the Fuzzy matter-element Model for Comprehensive Evaluation of the stability of coal mining subsidence. Analyzed each factor of the stability of coal mining subsidence, and constructed Fuzzy Comprehensive Evaluation of coal mining subsidence. With Fuzzy matter-element theory, make the stability of coal mining subsidence as matter element thing, Application of the things of the evaluation criteria and the fuzzy values to construct compound fuzzy matter element, and calculate the weights of each index with AHP, construct degree Evaluation Model with the concept of closeness, in order to achieve the stability evaluation of coal mining subsidence.
