摘要
低瓦斯隧道在铁路和公路工程中,比较常见;低气体通道瓦斯涌出量小,有时量不出来,它很容易被忽视或轻视。新建重庆铁路枢纽东环线陈家湾隧道,地层局部夹煤线及炭质页岩,且煤层不稳定。该文对于各种低瓦斯隧道施工瓦斯防治技术和措施进行分析和探讨,希望通过该研究,能够为低瓦斯隧道施工瓦斯防治工作提供一些参考和帮助。
Low gas tunnel is common in railway and highway engineering;gas emission in low gas channel is small and sometimes it cannot be measured.It is easy to be ignored or despised.The Chenjiawan tunnel on the east ring line of Chongqing railway hub is newly built,with coal line and carbonaceous shale in local stratum,and the coal seam is unstable.This paper analyzes and discusses various low gas tunnel construction gas prevention technology and measures,hoping that through this paper,it can provide some reference and help for gas prevention and control work in low gas tunnel construction.
