RESEARCH ON COAL MINING AND OUTBURST PREVENTION TECHNOLOGY FOR LARGE SECTION TUNNELS UNDER COMPLEX GEOLOGICAL CONDITIONS
Modern tunnel construction is prone to encountering complex geology,which not only increases the difficulty of tunnel construction,but also easily leads to various problems in the project,which is not conducive to the smooth construction of the entire tunnel project.Therefore,when encountering complex geological conditions,the construction unit should adopt reasonable methods to handle the construction site,among which,the coal mining and outburst prevention technology for large section tunnels is a common one.Based on this,this article proposes a coal mining and outburst prevention technology for large cross-section tunnels,targeting the characteristics of complex geological conditions.Taking a certain tunnel engineering as the research object,the specific application of this coal mining and outburst prevention technology is analyzed,providing better support for tunnel engineering construction under modern complex geological conditions.
