| 摘 要： | 为了研究高台阶抛掷爆破爆堆形态的模拟方法，在总结、分析大量的现场生产试验数据的基础上，完成了高台阶抛掷爆破爆堆形态的分类和高台阶抛掷爆破爆堆形态模拟的Weibull模型的建立。模拟结果表明：模拟爆堆曲线能与实测曲线较好地吻合，模拟结果较准确，爆堆始点爆破漏斗深度h为台阶高度的0.17～0.38倍，Weibull曲线参数α取值在0.919 3～1.245 0，β取值在1.185 9～1.832 4。

| Abstract: | A classification method and the Weibull simulation model of muckpile shape of high bench cast blasting were established based on analyzing the date from local experiments.The simulation results fit the experiments quite well.The value of parameterα of Weibull distributing model is in range of 0.919 3～1.245 0，1.185 9～1.832 4 for parameter β，and(0.17～0.38) H for h . |
