目前,爆破是岩石开挖的主要方法。工程中,实施岩石爆破时,一方面使开挖部分的岩石达到合理有效的破碎;另一方面尽可能减少爆破对边界以外岩石损伤或破坏,有效保护爆后保留岩石的稳定性,这是广大爆破专业人员追求的目标.然而,由于岩石性质和岩石爆破过程的复杂性,目前仍有很多问题亟待解决,急需了解岩石爆破的破碎机理以及影响爆破破碎的因素. At present, blasting is the main method of rock excavation. In the project, when implementing rock blasting, on the one hand, the rock of the excavation part can be reasonably and effectively crushed; on the other hand, the rock blasting is not damaged or destroyed by the blasting to the outside of the boundary as far as possible, and the rock stability after the blast protection is effectively protected is broad However, due to the nature of rock and the complexity of rock blasting, there are still many problems that need to be solved urgently. It is urgent to understand the mechanism of rock burst and the factors that affect the blasting.
