摘　　要：本文提出了台阶爆破岩石抛掷初始速度模型、抛掷角计算模型和抛掷与堆积物理模型，据此编制的计算机程序可以预测露天矿台阶爆破爆堆形状和岩石抛掷距离．The paper puts forward the model for initial velocity of rock throw during bench blasting,the calculation model for throw angle and the physical model for throw and stack. The computer program compiled on the basis of the above models can be used to predict the rock pile shape and rock throw distance during bench blasting of open-pits.
