Based on freezing parameters of freezing shaft sinking in west China mining area without directing at stratigraphic characteristics, which caused oblique large freezing hole, low freezing rate spread, difficult frozen wall circle, freezing hole water division when frozen wall unfreezing, shaft wall with temperature break and other problems, combined with Baleng Mine large water content, soft stratum, bad stability hydrogeological features, shaft freezing construction technology scheme was optimized, key point of borehole research and practice in freezing construction was focused, the annular space between the frozen pipe and surrounding rock was filled, extended slurry replacing the slurry in the freezing hole was constructed, the shaft construction experience was building up, the construction technology was mature and got good result.
