摘　　要：对在充分考虑炸药性能、岩石特性和爆轰波与孔壁相互作用等重要因素下的孔壁初始冲击波压力Ｐ_ｍ的计算结果进行了回归分析，得到了中威力炸药耦合装药孔壁初始冲击波压力Ｐ_ｍ的指数型表达式。利用该公式计算的Ｐ_ｍ与实验测试结果吻合较好。The regressive analyses have been carried out for the calculation results of initial shock pressure P_m of borehole which are gotten by taking many influence factors into full account such as the properties both of explosives and rocks,the interaction between detonation wave and borehole wall.The calculation formulas of exponential function of P_m of coupling charge have been achieved on the action of medium explosives in rock blasting.The calculation results of P_m with the formulas tally with those by measuring.
