Abstract

The evaluation of burst-proneness risks has affected the coal and rock mining progress and development. The quality evaluation system framework of burst-proneness risks indexes is established. Fuzzy evaluation index system is proposed to take into account various factors. As to index system, comprehensive fuzzy evaluation model and methods are setup and used to check for practical example. Using comprehensive fuzzy evaluation model and case study, it is concluded that, based on burst-proneness risk evaluation index system, comprehensive fuzzy evaluation method is applied to evaluate and solve the unclear boundary of some burst-proneness risks indexes and inaccurate fuzziness, which is proved to be practicable and feasible.
