| Abstract: | In view of the status,that there is not theoretical basis for project determination of shaft lining freezing in deep alluvium,in the paper a method which combines the finite element numerical simulation with theoretical calculation was brought forward,by which some important parameters,such as temperature field distribution regularity in frozen alluvium and thickness of frozen wall in Dingji Coal Mine were obtained.Practice indicated that the method can satisfy practical engineering demands. |
