Abstract:The evaluation index of rock burst has the characteristics of grey scale and fuzziness, so it is difficult to determine the reasonable index weight, resulting in the low accuracy of the traditional evaluation method, which can not meet the needs of the project. To solve this problem, based on set pair analysis and interval triangular fuzzy number, the SPA-ITFN evaluation model of rock burst was constructed. In the set pair analysis, the multivariate connection number can give consideration to the certainty and uncertainty of the evaluation index, and the interval triangular fuzzy number makes the definition between the grades more accurate. The evaluation index system of rock burst was constructed, which includes 12 indexes, such as mining depth, mining method and so on. The new evaluation model was used to evaluate the rock burst risk of six working faces in a coal mine. The evaluation results were compared with the fuzzy comprehensive evaluation, the evaluation model based on cloud model and D-S theory. The results show that the SPA-ITFN rock burst evaluation model is reasonable, accurate and the precision is high, and the evaluation results have high reference value for the monitoring and prediction of coal mine rock burst.
