Abstract: Given that the frozen wall of cretaceous freezing shaft after excavation will be affected by hydration heat generated by building wall concrete to lead to local heating or melting, and outer shaft wall will subject to freezing wall temperature and produce higher wall temperature difference between inside and outside, which is against strength increasing, and easy to produce temperature crack adverse effects on the shaft safety. In this paper, the use of ANSYS finite element numerical analysis software combined with the actual condition of Xinzhuang Coal Mine air shaft in Cretaceous strata, the shaft sinking frozen wall by freezing method and shaft lining temperature field interaction change rules were carried out finite element numerical analysis, which successfully guided the engineering practice.
