摘　　要：针对采用帷幕冻结法井筒下部冰点位置难以精确估算而导致施工困难的问题,利用回归分析法从竖向和径向温度场变化规律分析,得出了冰点地层位置,确定了安全施工范围,简化了施工工艺,达到了井筒安全施工的目的,为淮南矿区冻结法施工井筒确定安全临界值提供了重要的参考依据。In view of the heavy curtain lower freezing point position was difficult to accurately estimate wellbore freezing leading to construction problems,using the regression analysis method from the vertical and radial temperature field variation analysis,the freezing point of formation was concluded. The scope of safety construction was determined,the construction craft was simplified to achieve the purpose of safety construction. The technology provided important reference value of freezing method construction of Huainan coal mine shaft safety threshold.
