For water-uncouple charge,detonation wave shocks and presses water and stimulates shock wave,transmitting blasting pressure to rock through water and so its pressure of bore wall descended;for air-uncouple charge,however,products of detonation swelled and filled whole bore and then effects bore wall and its pressure of bore wall is the smallest among the three condit.
水不耦合装药,爆轰波冲击压缩水介质激起水中冲击波,由水将爆炸压力传递给岩石,孔壁冲击压力降低;而空气不耦合装药,爆轰产物则膨胀充满炮孔后再作用于孔壁,孔壁压力最小。
