| 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64 cm装药长度的效果对比，从而确定了合理的装药长度。

| Abstract: | 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. |
