摘要(Abstract)：

介绍了预测爆堆形态的弹道理论模型和Ｗｅｉｂｕｌ模型，提出了弹道理论的分条方法及抛掷轨道的计算公式。同时将Ｗｅｉｂｕｌ概率分布函数成功地引入爆堆形态的分布计算中，根据实测值提出了爆堆初始高度的修正方法。并以南芬露天铁矿为例进行了验证。
Two methods for muckpile profile prediction??ballistics theory model and Weibull′s distribution model are discussed in this paper The dividing methods of strip and the throwing angle of the rock in ballistic theory is also raised Meanwhile,the Weibull function which is used in probability analysis is introduced successfully to calculate the muckpile distribution The calculated initial height of the muckpile is revised according to the measured value Examples are demonstrated based on the measured data from Nanfen Open Iron Mine
