针对目前煤层冲击倾向性难以判定的问题,基于未确知测度理论对煤层的冲击倾向性进行分类研究。利用建立的未确知测度模型对5个典型煤样进行综合评判,并将结果与模糊综合评判方法比较。研究结果表明:未确知测度评价模型严谨、性能良好,具有一定的实用价值,为煤层冲击倾向性判别分类提供了一种新途径。
Aiming at the problem that the coal seam propensity is difficult to judge at present, the impact propensity of the coal seam is classified based on the unascertained measure theory. Five typical coal samples were evaluated comprehensively by using the unascertained measure model established, and the results were compared with the fuzzy comprehensive evaluation method. The results show that the unascertained measure evaluation model is rigorous, good in performance and has certain practical value, which provides a new way for discriminating and classifying the impact propensity of coal seam.
