柱状装药结构起爆药位置的设置对提高爆破质量的重要性

THE IMPORTANCE OF IMPROVING BLASTING QUALITY BY SETTING THE POSITION OF PRIMARY EXPLOSIVES IN THE STRUVTURE OF COLUMN CHARGE

柱状装药结构具有各类爆破的共性,起爆药在孔中的位置决定炸药爆轰的利用率、爆破效果及成本的高低,说明孔底起爆优于其它方式。

The Structure of column charge has the general character of blasting the utilization Rate of detonation wave,blasting effect and blasting cost are detemined by the position of Primary explosives in the hole.Bottom-hole detonation is better than the other ways.
