瓦斯隧道修建过程中的煤与瓦斯突出、瓦斯爆炸、煤尘爆炸以及煤层坍塌,不仅危及施工及结构安全,而且影响隧道施工进度。文章以蛟岭瓦斯隧道为例,针对蛟岭瓦斯隧道塌方的特点,制定实施了蛟岭隧道瓦斯塌方区前区加固方案和塌方体处理方案,并制定实施煤和瓦斯突出危险性预测,根据加固后塌方地段的监控量测结果和有限元计算结果,所选处理方案取得很好的成效。 Gas and gas outburst, gas explosion, coal dust explosion and coal seam collapse during the gas tunnel construction not only endanger the construction and structural safety, but also affect the construction progress of the tunnel. Taking JiaoLing Gas Tunnel as an example, aiming at the characteristics of JiaoLing Gas Tunnel landslide, a scheme of consolidation and landslide treatment for the gas collapse zone in JiaoLing tunnel was formulated and implemented, and the risk prediction of coal and gas outburst was formulated. According to the reinforcement After the landslide monitoring and measurement results and finite element calculation results, the selected treatment program achieved good results.
