导爆管雷管孔内外微差爆破网络的研究

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

对用 m+1个段位的微差导爆管雷管组成 n排孔、每排 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 ,指出采用国产导爆管雷管每排孔不超过 3孔才能达到单孔单响目的 。

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.
