摘要
从岩石性质出发,区分了坚固性和可爆性的差别,以现有岩石可爆性分级为参考,从岩石物理力学参数出发,选出了对岩体可爆性有重要影响的物理力学参数,并充分考虑动力冲击荷载作用,融合现场工作经验,为岩石可爆性及露天矿爆破炸药单耗选取提供了参考。
This article distinguishes difference between robustness and explosiveness based on the properties of rocks.Taking the existing rock explosiveness classification as reference,we choose the physical and mechanical parameters of rock which has an important effect on rock explosiveness based on the physical and mechanical parameters of rock and consider the effect of dynamic impact loading,which provide reference for rock explosiveness and the single consumption selection of open pit blasting explosive.
