摘要/Abstract

摘要： 通过分析岩石爆破机理及工程实验提出大炮孔预裂导向的爆破方法，即BHPO预裂爆破方法。方法是集露天大孔径深孔预裂爆破及普通预裂爆破优点的新型预裂爆破模式，是目前预裂爆破改进完善的新技术。BHPO预裂爆破方法是建立在现代力学的基础之上，可以更好的达到保护边坡的目的。

Abstract: Blast hole pre-split orientation(BHPO) is proposed based on the analysis of rock blasting mechanism and pre-engineering experiments. It's a kind of new type pre-split blast model which combines the advantages from large hole size deep hole pre-split blast in the open pit and normal pre-split blast. It's the new improved technology of pre-split blast at present. The BHPO method is based on modern mechanics which could do better on slope protection.

Key words: Blast hole orientation, BHPO, Blasting fracture mechanics, Blasting stress
