Development and Prospects of Construction Technology in Drill-and-Blast Mountain Tunnel
As mountain tunnels evolve towards greater height,depth,size,and length,the drill-and-blast construc-tion technique is gradually becoming inadequate to meet the current demands of tunnel construction.This paper re-views the development status and challenges faced by the drill-and-blast construction technique in mountainous tunnels,covering aspects such as construction theory,technology,equipment configuration,and environmental pro-tection.It provides a comprehensive review of the evolution of drill-andblast techniques,summarizes the current technical status of drill-and-blast tunnels,identifies the existing technological bottlenecks and industry pain points,and anticipates future development trends for drill-and-blast mountain tunnel construction technology,aiming to offer references for the future advancement.
