The technology , which is developed on the basis of perfora ting techniques for oil wells and cement injection techniques , can not shoot thr ough the frozen pipe wall at predetermined ground location using energy - gatheri ng - blasting techniques , but also consolidate shaft wall rock by cement injectio n and filling along the frozen pipe and perforated hole s trajectories , achievi ng leakageproof of shaft walls and reducing vertically - added force 它利用聚能射孔爆破技术，在预定地层位置将冻结管射穿，同时在地面利用冻结管及射孔弹道对特定地层进行注浆充填加固，既可实现井壁堵漏，又能减少由于地层沉降对井壁的垂直附加力。
