塑料管导爆系统是运用导爆管传爆、起爆特性,通过孔外不同的连接方式,实现孔内导爆管雷管按一定的顺序进行起爆的起爆网路。文章结合工程实践,研究运用四通连接件传爆技术,即通过四通连接件把主爆管爆轰波分流瞬间传递给几根被爆导爆管,无需传爆雷管。这种传爆方法经济适用,最终得到了广泛应用。 Plastic tube detonation system is the use of detonating tube explosion, detonating characteristics, through the hole outside the different connections, to achieve the hole detonator detonator detonated in a certain order detonating network. Combined with engineering practice, this paper studies the use of four-way connector blasting technology, that is, through the four-way connector to the main burst detonation wave diversion instantaneous burst delivered to a few burst tube, without the need for blast blaster. This method of blasting is economical and has been widely used in the end.
