Simulation model for muckpile shape of high bench cast blasting in surface coal mine
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 parameter α 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.
