爆破中所发生的困难,大多是由于对岩石破碎性质了解不够,以及药包位置和起爆时間間隔不适当所致。常常是通过对爆破效果的观测来发現錯誤;岩石破碎是否均勻、是否产生根底、破碎猛烈抛擲、以及类似不良現象。如果所用炸药适应于生产条件,則可应用某些标准,以促进爆破效果。这些标准也有助于提供关于改善爆破綫索,以克服爆破中所遇到的困难。这些标准是实用的,且易于应用,共构成要素为两个众知的基本参数:药包直径和边帮高度。这些标准如下:
Most of the difficulties encountered in blasting are due to inadequate knowledge of the nature of rock fragmentation and the inappropriate location of the packs and improper timing of initiation. Often mistakes are made by observing the effect of the blasting; whether the rock is broken evenly, whether the foundation is created, the thrashing is broken, and the like is bad. If the explosives used are adapted to the conditions of production, certain criteria may be applied to promote the blasting effect. These standards also help provide clues to improving explosions in order to overcome the difficulties encountered in blasting. These standards are practical and easy to apply, with a total of two well-known basic parameters: the diameter of the pack and the height of the side. These criteria are as follows:
