针对西部软岩地区矿井建设采用人工冻结技术出现的冻结壁不交圈的问题,分析了传统冻结壁交圈判定方法在西部地区的不足之处,阐述采用冻结器纵向测温技术在冻结壁交圈判定中的作用。并结合实际工程,给出了纵向测温技术在检测冻结壁开窗部位、修复过程监测及判定冻结壁交圈的应用,明确了该技术在人工地层冻结法凿井中的重要应用意义。
In view of the problem that the freezing wall in the soft rock area of western soft rock area is constructed by artificial freezing technology, the problems of the traditional frozen wall intersecting circle analysis method in the western area are analyzed. The disadvantages of the traditional freezing wall cross-circle determining method in the western area are analyzed. The role of circle determination. Combined with the actual project, the application of longitudinal temperature measurement technique in the detection of fenestration of freezing wall, the monitoring of the repair process and the determination of the intersecting of frozen wall were given. The important application significance of this technique in drilling by artificial freezing was given.
