摘　　要：依据岩石爆破装药结构的真实状况,建立了不耦合装药爆破岩石、爆轰产物、空气强冲击波相互作用过程的物理模型。给出了求解岩石冲击波初始参数的基本方程和极曲线方法。模型图像清晰,较全面地反映了爆破的真实过程,计算结果更加符合实际。According to the reality of charge structure in rock blasting, a physical model on the reaction among the rock, detonation products and shock wave in air is achieved with uncoupled charge in this paper. The basic equations and the polar curve method to solve the initial parameters of shock wave in rock are also developed. The diagram of this model is clear to represent the real blasting procedure comprehensively, and the results of calculation coinside with reality quite well.
