摘要
为了准确评判穿越煤层的瓦斯隧道的危险性等级,在深入分析隧道瓦斯突出事故的基础上,选取了地层岩性、地质构造、煤层厚度、隧道埋深、水文地质条件等作为评价瓦斯隧道危险性的评价指标。然后引入不确定型层次分析法和理想点法,建立了瓦斯隧道危害危险性评价模型,并应用该模型对四条瓦斯隧道的危险性等级进行评价。结果显示:应用该模型所得到的瓦斯隧道危险性等级与实际等级完全一致。
In order to evaluate the hazard degree of gas tunnel crossing coal accurately, the formation lithology, geological stnlcture, coal seam thickness, tunnel depth, and hydrogeology condition are chosen as evaluation index of the hazard of gas tunnel, on the basis of in-depth analysis of tunnel gas outburst accident. Hazard risk evaluation model of gas tunnel is established by applying UAHP and ideal point method, and then the hazard degree of four gas tunnels is evaluated using the model. The result shows that the hazard degree of gas tunnel obtained from the model is fully consistent with the actual level.
