Current situation of study and application of hole-by-hole blasting on mechanism,delay time and effect is analyzed;developing further problems to be solved are given in this paper.
主要从逐孔爆破技术机理、微差时间和爆破效果等方面分析了该技术的研究和应用现状,同时分析了该技术需要进一步解决的问题。
In this programme,the actions of "randon simultaneousness"and "short millisecond delay"spur on the superimposition of blasting stress wave and the energy-utilization of blasting gas to be carried out more fully, cause the formation of blasting oracle and the phenomenon of intersecting or branching more extensive and make.
该爆破方案的“随机同时”和“短时微差”作用，促使爆破应力波的叠加及爆炸气体能量利用更加充分，形成的爆破裂纹和交叉分支现象更为普遍。
