摘　　要：在既定的孔距、排距、孔径等参数下,利用LS-DYNA模拟了不同装药长度的爆破效果。针对表征岩石破碎效果较为直接的Von Mises应力、Y方向位移、Y方向速度分别进行56 cm和64cm装药长度的效果对比,从而确定了合理的装药长度。Blasting effect of different charge length were simulated on fixed parameters like pitch of holes,distance between two rows,aperture by LS-DYNA.Effect comparison of charge length 56cm and 64cm were done separately aim at Von Mises Stress,Y-displacement,Y-velocity which the characterized rock crushing effect is much direct,and finally the reasonable charge length was confirmed.
