| Abstract: | In order to solve the problem that the evaluation indexes in the comprehensive index evaluation method, which is commonly used in the evaluation of the risk of rock burst in coal mines, are difficult to gain objective weight in engineering practice, the comprehensive index evaluation method is improved, based on the entropy weight method which gives objective weight and the variation degree of each evaluation index, the entropy weight value of each index is calculated by information entropy principle, and the index weight is more objective by optimizing each evaluation index. The reliability of the comprehensive evaluation model is further proved by comparing the results of the mechanical test and the comprehensive index method. The research results have been successfully applied in the safe mining process of 16-4 working face of a mine in Inner Mongolia. It is found that the mine has weak impact risk. |
