基于未确知测度理论建立煤层突出危险性预测方法,构造未确知测度模型,计算各评价指标的未确知测度值.根据熵理论计算各评价指标的权重,用置信度识别准则进行等级判定,得出预测结果.该方法适用于解决煤层突出危险性预测过程中诸多因素的不确定性问题,还能对其进行定量分析.实例证明,用未确知测度理论方法对煤层突出危险性进行预测,计算结果与实际情况吻合较好. Based on the unascertained measure theory, the prediction method of the coal seam salient danger is established, the unascertained measure model is constructed, and the unascertained measure value of each evaluation index is calculated.According to the entropy theory, the weight of each evaluation index is calculated, and the confidence level , And the prediction results are obtained.The method is suitable for solving the uncertainties of many factors in the process of predicting the dangerous degree of coal outburst and can also quantitatively analyze it.Examples show that using the unascertained measure theory method to carry out the prominent danger of the coal seam It is predicted that the calculated result is in good agreement with the actual situation.
