摘　　要：结合赵楼矿深厚表土冻结法凿井工程,介绍了冻结法凿井中的地层冻结工程相关参数监测、井帮温度与变形监测和井壁收敛监测、上部已成型井壁段的温度和受力与变形监测,依据监测结果及其规律分析,主井及时中途套壁,副井在出现井壁裂隙的情况下坚持大段高掘砌。赵楼矿主副井外壁掘砌平均速度分别为88.33 m/月和93.21 m/月,内壁套砌速度均超过280 m/月。两井筒施工与施工组织设计相比分别提前28 d和26 d通过冻结段,节约直接冻结运行费约396万元,实现了深厚表土冻结法凿井的安全、快速施工。In combined with the mine shaft freezing sinking project in deep thick overburden of Zhaolou Mine,the paper introduced the data monitoring and measurement,mine shaft wall temperature and deformation monitoring and measurement,mine shaft linear convergence monitoring and measurement,the temperature,stressed and deformation monitoring and measurement of the top section shaft linear related to the ground freezing project of the freezing shaft sinking.According to the monitoring and measure results and the law ...
