摘　　要：深孔一次爆破成井技术能实现竖井高效掘进。通过理论分析,提出了深孔一次爆破成井技术方案,给出了爆破参数设计依据及设计方法,并以成功的工程案例进行了佐证。The shaft excavation technology by once deep-hole blasting could be used to realize high-efficiency shaft excavation. Based on the theoretical analysis, the technical scheme of shaft excavation by once deep-hole blasting was put forward,and the design standards and methods of the blasting parameters were obtained. Meanwhile, the successful engineering example proved that this technology was feasible.
