分析了我国机井涌水不足的原因，探讨了井内水中爆炸其冲击波及气体脉动对井壁围岩的作用机理，确定了井内爆破参数的设计原则，并应用于工程实践。结果表明，理论分析与实践吻合较好。
The reason of insufficient water inrush in our country was analyzed, the mechanism of shock wave and gas pulsation on the surrounding rock in the well was discussed, and the design principle of blasting parameters in well was determined and applied to engineering practice. The results show that the theoretical analysis is in good agreement with the practice.
