摘要
阐述了根据地质条件,合理调整爆破参数,实施全断面依次成巷光面爆破施工,使开挖巷道成型规整,新挖岩面破坏少,巷道稳定性高,支护维护量少,提高了巷道掘进综合经济效益。
According to geological conditions, the blasting parameters are reasonably adjusted. The smooth surface blasting method for full--section sequential tunneling is adopted, which brings the advantages： the form of tunnel is of good tidiness; the new rock surface is less damaged; the stability of tunnel is high; the support need is less; and the integrated benefit of tunneling is increased.
