摘    要:为了封堵某矿井异常出水的水文孔,基于液氮气化时剧烈吸热的原理,提出了采用液氮土层冻结技术快速冻结水文孔的解决思路.通过在出水水文孔下放液氮冻结管,液氮气化吸热,直至冻结水文孔及周围土体.在矿井建设中其他封水措施都失效的情况下,液氮快速冻结取得了理想效果;这表明液氮快速冻结技术可以作为应用冻结法出现险情时的补救措施.

Abstract:In order to seal the abnormal water inrush from the hydrological borehole in a mine shaft,based on the violent endothermic principle during the liquid nitrogen vaporization,the application of liquid nitrogen ground freezing technology was provided to solve the rapid freezing hydrological borehole issue.With the liquid nitrogen freezing tube in the hydrological borehole with water come out,the vaporization of the liquid nitrogen would have heat absorption until the hydrological borehole and the surrounding s...
