摘要
岩体结构面对爆破效果有显著影响 ,当最小抵抗线与结构面平行时 ,极易造成冲炮和隔墙。鉴于此 ,本文介绍一种千枚岩硐室爆破的设计和施工方法 ,取得了较好的爆破效果。
Rock joint has a strong influence on blasting result,when burden and fault are parallel,this easily results in rushing out of the chamber and partition wall.So that designations and construction method of chamber blasting of phyllite are introduced,it obtained good blasting effect in this paper.
