摘要
采用水封聚能药包爆破大块既克服了钻孔的麻烦 ,又克服了糊炮浪费炸药的缺点 ,对降低二次爆破炸药单耗 ,降低粉尘浓度 ,提高出矿效率等有明显效果。本文介绍了用于破碎大块的聚能药包的结构及使用效果。
Fragmentation of oversized boulders with water-stemming shaped charges does not need hole drilling which is troublesome and avoids explosive waste as with exposed charges, thereby cuts explosive ratio for secondary blasting and reduces dust concentration. As a result, efficiency for ore removal is enhanced. This paper presents the structure of the shaped charge and its application performance.
