关于炮眼爆破法起爆药包置于炮眼中的位置方向问题，至今国内外各有论述，目前尚无统一认识。现根据我们实践中的教训谈谈看法。一、炮眼内起爆药包位置在坑道爆破装药操作问题上，五、六十年代，炸药说明书和有些矿山的操作规程中，明文规定起爆药包装填在眼口第二个药包的位置最佳，并把雷管的聚能穴朝向炮眼底顺着炮眼深度摆放，一般称之为正向起爆。这种爆破理论是药包爆炸时产生强大的冲击波，将直接通过聚能穴冲击起爆后面的各个药包。后来，在生产实践中，又认为起爆药包置于炮眼底并反向置
As to the location and direction of the blasting cartridge detonated in the blasthole in the blasting blasting method, there has been discussion both at home and abroad so far, and there is no unified understanding. Let’s talk about the lessons of our practice. First, the location of the detonating kits in the blasthole In the tunnel blasting charge operation problems, the fifties and sixties, explosives brochures and some mines operating procedures, expressly detonated drug packaging filled in the second eye pack the location of the pack Well, and the detonator of the converging hole towards the bottom of the gun along the depth of the blasthole, generally known as positive detonation. This theory of blasting is a powerful shock wave generated by the explosion of a kits, which will directly impact the various kits behind the initiation of a kennel. Later, in the production practice, it was considered that the detonating kits were placed at the bottom of the blasthole and set in reverse
