| 摘 要： | 初步探讨了炮孔水耦合装药爆破时，耦合水中爆炸冲击波的形成和传播，求算了冲击波的初始参数和孔壁处冲击波参数；应用弹性理论和波动理论推导出了正入射情况下孔壁岩面上的冲击压力，并与同样装药和岩石条件下空气不耦合装药爆破时的孔壁压力进行了比较，结果证明：炮孔水耦合装药比空气不耦合装药爆更能提高爆炸能量利用率。增强破岩能力。

| Abstract: | The article discusses the formation and propagation of the shock wave when water couple change blasting in the hole, and calculates the initial parameters of the shock wave and parameters of the shock wave on the hole wall. Applying elastic theory and fluctuating theory, the article deduces the shock pressure on the rock of hole wall in case of normal incidence, and compares it with the hole wall pressure in air-uncoupling charge blasting with the same charge and rock property . The result shows that the water-couple charge in the hole can significantly increase the utilization ratio of blasting energy and strengthen the capability of crushing rock than air-uncouple charge. |
