对属性测度理论进行优化,并将其用于煤与瓦斯突出危险性的评判。选取开采深度、瓦斯压力、解吸速度、煤层强度和节理裂隙发育程度作为煤层突出危险性的评判因子,建立了属性测度评判模型。将其用于评判12个样本煤层的突出危险性并将结论与实际情况作了对比分析,该法的准确率达91.67%。
The property measure theory is optimized and used to judge the danger of coal and gas outburst. Selecting the mining depth, gas pressure, desorption rate, coal seam strength and degree of joint and fissure as the evaluation factor of coal seam salient danger, the attribute measure evaluation model is established. It was used to judge the outstanding risk of 12 samples of coal seam and the conclusion was compared with the actual situation. The accuracy of this method was 91.67%.
