摘要
在南掌河电站引水隧洞开挖爆破工程中,通过分析计算和现场试验,确定了光爆参数、炮眼布置和炸药用量,提出了在裂隙发育条件下小断面隧洞开挖中实施全断面光面爆破的方法及爆破设计中的关键参数。
In the blasting excavation works of diversion tunnel of Nanzhang River Hydropower Station, the smooth blasting parameters, layout of blasting holes and explosive charges are determined by blasting test in situ; The total-section smooth blasting method for small-sized tunnel in fissured rocks and relevant blasting parameters are recommended.
