Abstract：The diameter of western air shaft in Zhaogu No. 1 Coal Mine is 6. 0 m, and the depth is 636. 8m, which crosses the 502. 51m thick alluvium and 28. 69m thick bedrock weathering section. Aiming at the thick alluvium and complicated geological conditions, freezing construction is applied in the design, with a freezing depth of 589m to ensure the safety of shaft construction. The double-layer reinforced concrete plastic sandwich composite shaft structure is used in the wellbore of the frozen section, maximum thickness of the inner and outer shaft wall is 900mm and 800mm respectively.
