摘　　要：介绍中国冻结法凿井60余年发展经历的引进消化、探索改进、完善提高、创新攀高四大阶段,阐述中国在深厚冲积层冻结段井壁结构、井壁用C60~C100高强高性能混凝土、冻结壁设计理论体系、多圈孔冻结工艺、冻结壁形成特性工程预报与调控、冻结壁径向位移实测与掘砌段高调控、冻结段安全快速施工等关键理论与技术成就和现状,这些构成具有中国特色的深厚冲积层冻结法凿井理论和技术体系。还对冻结壁设计理论和发展、井壁结构设计与应用、冻结壁温度场理论与应用技术、深部立井基岩冻结和斜井冻结技术等方向存在的问题进行了展望和建议。The paper presented four high stages of the introduction and digestion, the discovery and modification, the perfect improvement and the innovation upgrading during the over 60 years develop- ment of the mine ground freezing shaft sinking in China and stated the shaft liner structure at the ground freezing section in the deep and thick alluvium, the C60~C100 high strength and high per- formance concrete applied to the mine shaft liner, the design theoretical system of the freezing wall, the freezing technique with multi freezing ring boreholes,the characteristics engineering forecast and adjusted control of the freezing wall formation, the radial displacement measurement of the freezing wall and adjustment control of the lining section height,the safety and rapid construction of the freez- ing section and other key theory and technical achievements as well as the present status in China. All above formed the mine shaft sinking theory and technical system with the China characteristics deep and thick alluvium freezing method. An outlook and proposals were provided on the design theory and development of the freezing wall, the design and application of the mine shaft liner structure, the tem- perature field theory and application technology of the freezing wall, the base rock freezing in the deep mine shaft and the mine inclined shaft freezing technology as well as the problems existed.
