摘　　要：运用爆炸冲击波和应力波的理论及其在岩石介质中的传播和反射规律,对球状装药产生的爆破破坏范围进行了研究,导出了球状药包的岩石爆破漏斗计算公式。应用Starfield迭加原理,推导确定了延长药包(柱状药包)爆破漏斗参数的理论解。Based on the theory of blasting shock-wave and stress-wave and the law of their propagation and reflection in rock medium, the blasting breakage range from spherical charge is studied, and then the crater calculation formula for rock blasting with spherical charge is educed herein. Finally, the theoretical solution of the crater parameters for the blasting with strip-shaped charge （colmnn charge） is derived and determined with Starfield＇ s superposition theorem.
