摘　　要：定向爆破抛掷距离计算常采用体积平衡法或抛体堆积法,这2种计算方法的理论基础和设计原则各不相同。为了验证其客观性、准确性,通过选取不同爆破参数和布药结构,进行系列模拟试验并加以分析和研究,研究证明体积平衡法更加符合客观规律,该结论有助于指导定向爆破设计与实践。At present, two methods, the volume equilibrium method and thrown piling method arc widely used in calculation of thrown pilling of directional blasting, of which the academic foundation and design principle are different. In order to validate the objectivity and validity of the methods, the paper analyzes and researches the casting distance under different instances by the field simulation test of adopting different blasting parameters and layout of charge. The results indicate that the academic foundation corresponds objective law and provide a reference to design and practice in directional blasting.
