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 g the new improved technology of pre-split blast at present. The BHPO method is based on modern me- chanics which could do better on slope protection.
