摘　　要：本文介绍了应用高速摄影结果建立的合理微差间隔时间的数学模型,以及通过现场和室内模报试验进行验证的结果,最终结合爆破地震模拟的方法,确定了水厂铁矿台阶爆破的合理微差间隔时间。Based on the data of high-speed photograph, a mathematical model of reasonably selecting delay interval for bench blasting has been established. The field blasting experiments and simulation in room have proved that the model is feasible. For large scale prodution blasts in shuichang iron mine, a combination of the model and the vibration simulation is used to choose the reasonable delay interval.
