非电毫秒雷管是七十年代世界上出现的一种新型起爆器材。我队使用的是由一根塑料导爆管和一个8号毫秒雷管掐合而成（图1），其产品延时分为十个段别（表1）。使用时，只要将工作面所有炮眼的导爆管捆扎在一起，用一个火雷管轰击，通过导爆管内高能炸药传播爆轰波引爆雷管药包，使其一次全断面起爆（图2）。我们从80年8—9月份开始试用，通过生产实践证明，塑料导爆管及非电毫秒
Non-electric millisecond detonator is the seventies appeared in the world a new type of detonating equipment. My team used a plastic detonating tube and a No. 8 millisecond detonator pinch together (Figure 1), the product delay is divided into ten sections (Table 1). Use, as long as all the blasting face of the blasthole bundled together, with a fire detonator bombardment, detonation by detonating high-explosive explosives detonating detonator detonator kits, making it a full face explosion (Figure 2). We started trial from August to September in 1980, proved through production practice, plastic detonating tube and non-electric millisecond
