起爆方式对岩石爆破破碎影响的数值模拟研究

Numerical Simulation on Rock Fragmentation by Blasting Under Different Detonation Manners

应用损伤模型理论和数值模拟方法，对岩石爆破破碎过程中起爆方式的影响进行了模拟研究． 模拟结果表明，起爆方式不仅影响岩石的爆破效果，更重要的是影响爆破漏斗的形成过程和岩石的破坏方式．

Damage model and numerical simulation are used in the study of rock fragmentation under different detonation manners. The results show that the detonation manners affect not only rock blasting, but also the forming procedures of blasting crater and forms of rock fragmentation.
