Abstract

Based on the rock mass quality classification, this paper proposes a new prediction formula for the attenuation parameters of blasting vibration velocity in jointed rock masses. A parametric sensitivity study is also conducted while considering a variety of influence factors, including joint angle, joint spacing, and joint stiffness. Compared to the existing blast-related standard in China, in which the attenuation parameters are merely derived from rock hardness, without considering the joint characteristics of rock masses, the proposed prediction formula is proved to be a more promising approach to carry out accurate blasting design and blasting safety assessment.
