摘要
隧道穿越含瓦斯煤层施工过程中的突出风险一直是瓦斯隧道施工的难题。本文首先统计分析了2001—2021年我国瓦斯隧道揭煤施工事故,辨识出对隧道揭煤施工突出风险有影响的主要因素,随后通过文献查阅等方式构建了53个样本集,最后运用支持向量机(SVM)方法对揭煤施工突出危险性进行预测研究。
The protrusion risk during the construction of tunnels through gas-bearing coal seams has been a difficult problem in gas tunnel construction.In this paper,we firstly analyzed the accidents of coal uncovering in gas tunnels in China from 2001 to 2021,and identified the main factors that have influence on the protrusion risk of coal uncovering in tunnels,then we constructed 53 sample sets by literature review,and finally used the support vector machine(SVM)method to predict the protrusion risk of coal uncovering.
