Analysis of hydrologic hole anomaly by freezing method of north inlet air shaft in Xuchang Iron Mine
WANG Long
Abstract：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 o-riginal hydrologic hole failed.As a result,the new hydrologic hole was re-constructed when work re-sumed 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.
