摘要
针对当前高速公路瓦斯隧道开挖作业中存在的安全隐患,文章总结了现有高速公路隧道揭煤防突技术类型,并基于大梁子隧道这一实际工程案例,提出了一种全面的高速公路瓦斯隧道揭煤防突技术体系.该体系遵循"优先采取区域防控措施,必要时采用局部防控补充"的基本原则,对高速公路瓦斯隧道揭煤防突技术进行前期预测,并检验区域与局部防突技术的实施效果,旨在为隧道工程的设计与建造提供参考.
Abstract
In view of the potential safety hazards in the excavation of expressway gas tunnel,this paper summarizes existing types of coal uncovering and outburst prevention technologies for expressway tunnels,and proposes a comprehensive coal uncovering and outburst prevention technology system for expressway gas tunnels based on the actual engineering case of Daliangzi Tunnel.The system follows the basic principle of"giving priority to regional prevention and control measures,and adopting local prevention and control supplements when necessary".It predicts the coal uncovering and outburst prevention technology of expressway gas tunnel in the early stage,and tests the implementation effect of regional and local outburst prevention technology,aiming to provide reference for the design and construction of tunnel engineering.
