| Abstract: | 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. |
