Based on wavelet packet analysis of blasting seismic energy and the basic theory of damage mechanics,this paper analyzes the damage effect of blasting vibration with low frequency on rock,and introduces a theory that blasting vibration has the damage effect of tension and compression on rock,which explain the reasons of rock damage from the perspective of energy,and overcome of single criterion for rock damage.The summarized universal theory about damage effect of blasting vibration with low frequency on rock provides the basis theory for the further study.
