摘要
为对比白垩系地层冻结孔有无偏斜情况下深立井冻结壁温度场的差异,以内蒙古泊江海子矿副井为工程背景,采用数值模拟方法,建立了冻结孔有无偏斜情况下的数值计算模型,同时结合实际测温孔量测数据,重点分析了冻结造孔偏斜对白垩系地层冻结壁形成规律的影响。
In order to compare the difference of the temperature field in the frozen shaft of deep vertical shaft with or without deflation of the freezing holes in the Cretaceous formation,in Inner Mongolia, the Bojianghaizi mine auxiliary shaft as the engineering background,using numerical simulation method,the numerical model of frozen hole with or without deflection was established,at the same time with the actual temperature measurement hole data,the emphases are given to analyze the influence of freezing hole-forming deviation on the formation of frozen wall in Cretaceous strata.
