Research on Coal Uncovering and Outburst Prevention Technology for Expressway Gas Tunnel
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.
