| Abstract: | Based on the established macro equivalent elastic constants of fractured rock, the constitutive relations of rock dynamic damage around the bore hole and their corresponding numerical calculating formats are deriver in this paper.This method is used to calculate the damage depth of surrounding rock caused by contour control blasting.Calculation example shows that the method proposed in this paper is feasible. |
