Study on the Influences of Empty Hole and In Situ Stress on Blasting-Induced Rock Damage
Blasting has been used extensively in deep underground excavation. In this paper, a numerical simulation LS-DYNA was carried out to investigate the influence of in situ stress and empty hole on rock fracture development. Based on the simulation process and existing laboratory data, the micromechanic...
