摘要
以洛阳村隧道Ⅲ级围岩段光面爆破工程为例,阐述了在中硬岩条件下隧道光面爆破材料选择及爆破参数的选取方法,重点介绍了全断面光面爆破及其钻爆设计流程,对实施程序进行了论述,并对爆破技术要求以及注意事项作了总结,以确保施工安全。
Taking the smooth blasting of Level Ⅲ surrounding rock of tunnels at Luoyang Village as the example, the paper illustrates the selection for tunnel smooth blasting materials and parameter under the soft and hard rocks, mainly introduces the whole section smooth blasting and its drilling and blasting design procedure, indicates the requirements for the implementation procedure and the precautions of the smooth blasting.
