摘　　要：许昌铁矿北进风井采用了冻结施工技术。由于水文孔施工完成后经历了较长的停工期,导致原有水文孔失效。因此,在十年后重新开工时重新施工了新水文孔,并采取了多项措施以确保新水文孔能够准确反映冻结壁的交圈情况,为未来类似工程提供了宝贵的参考经验。Freezing construction technology has been adopted in the north inlet air shaft of Xuchang Iron Mine.Due to the long downtime after the completion of the hydrologic hole construction,the original hydrologic hole failed.As a result,the new hydrologic hole was re-constructed when work resumed ten years later,and a number of measures were taken to ensure that the new hydrologic hole accurately reflected the intersection of the freezing wall,providing valuable reference experience for similar projects in the future.
