Hu Tao ,Li Xianglong,Guan Si ,He Lihua

Strategic Study of CAE 2014, Volume 16, Issue 11,   Pages 36-41

Abstract:

This paper numerically simulates the stress development and generates a three-dimensional model of the medium-deep hole blasting in infinite rock mass for continuous charge and divided charge in blasting by using the large-scale nonlinear dynamic analysis software LS-DYNA and the elastic-plastic model *MAT_PLASTIC_KINEMATIC and JWO-EOS. The difference of the decreasing rate in Von Mises effective stress of blasting, element effective stress peak in free face, the bore wall stress and acceleration are investigated. It is shown that divided charge could greatly improve the blasting effect by engineering blasting practice.
