导爆管雷管孔内外微差爆破网络的研究

对用m＋1个段位的微差导爆管雷管组成n排孔、杂排m孔单孔单响的微差爆破网络的约束条件进行了讨论，探讨了雷管起爆误差对这种爆破网络的影响，指出采用国产导管雷管每排孔不超过3孔才能达到单孔单响目的，因此须研制生产高精度间隔微导爆管雷管。

Study on Millisecond Blasting with Non-electric Detonator Outside and Inside the Hole

The restriction conditions for a kind of milli se cond blasting net are discussed, and the net consists of (m 1) kinds of millisec ond detonators. With this net, we can realize only one hole blasting at each ti me point. There are n rows of holes and there are m holes in each row. And the detonator hang-fire error affecting the net is also discussed. At last, autho r points out that if non-electric detonator made in China is used and only one h o le blasting at each time is to be realized, each row should not exceed three hol es. As a result, it is necessary to study and develop a new kind of non-electr ic detonator with certain delay time and high precision.
