摘　　要：通过建立松散体离散单元模型,采用ALE耦合算法,模拟了松散介质坍塌堆积物的抛掷爆破过程。分析了装药量与抛掷率的关系,并与现场试验结果进行了比较分析,模拟结果与现场试验结果基本吻合,证明了数值模拟方法的可行性,为类似相关工程爆破方案的优化提供了参考。By establishing the discrete element model of loose object and using ALE coupling algorithm,the simulation of loose medium＇s casting blast process is performed. Meanwhile, the relationship between charge weight and casting rate is analysed, and the calculated results are also compared with those in field experiment and they are identical basically. The simulation results show this numerical simulation method is feasible and provide reference for optimization of similar blasting scheme.
