| 摘 要： | 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。

| Abstract: | Based on the uncertainty measurement theory,the identification and classification model for rock burst tendency of coal was established.Uncertainty measurement function was obtained based on the experimental values.The information entropy was used to calculate the index weight of factors,and the functional relationship between the weight and the experimental values was established,also,the credible degree recognition criterion was applied to identification and classification of rock burst tendency.Five typi... |
