摘要
岩体结构面对爆破效果有显著影响。当最小抵抗线方向与层面平行时 ,可能造成冲炮 ,不仅减少爆破方量 ,而且易留根底或隔墙。本文介绍的层状矿体硐室爆破实例 ,取得了较好的爆破效果 ,对类似的爆破具有一定的参考价值。
The blasting effect is notably influenced by rock structure.When the blasting director is horizontal with rock bedding face,towards blasting probably appear,blasting volume will be increased and foot wall easily appear.This paper briefly introduce chamber blasting examples on bedding ore body,better blasting results achieved,which could serve as a reference for similar blasting.
