在有水的岩层钻孔内,采用不耦合装药进行水中孔内爆破后,产生的爆炸能量冲开孔壁岩层已有裂隙,扩展和产生新的径向裂隙,而井壁却不坍塌,孔壁围岩仍能保持自身维护能力。将这种水下径裂爆破技术用于供水井,能够增大沿井壁渗透流速和渗透量,从而增大出水量。由于这一技术所需成 In the water-bearing rock formation, the explosion energy generated by the uncoupled charge in the water hole excites the existing fractures of the pore rock, expands and produces new radial fractures, and the wall of the well does not collapse, Hole wall rock can still maintain its own ability to maintain. Applying this underwater radial blasting technique to a water supply well increases the rate of permeation and the amount of permeate along the wellbore wall, thereby increasing the amount of water produced. Due to the technology required
