摘要(Abstract)：
介绍了在土中双层（上、下层）药包短延时爆破２００余次模型试验的研究成果，给出了几组优化爆破参数及延时起爆间隔时间，并应用于在黄粘土中快速构筑垂直短洞，证明了这一方法有优越性。
Based on the model experimental results for more than 200 blast tests during short-delayed double-deck charge blasting,optimal blasting parameters and time interval of delaying detonation are obtained.These achievements have been applied to scoop out a vertical short-hole in yellow clay. And then the superiorities of a short-delayed double-deck charge blasting are also discussed.
