| Abstract: | On the condition of the frozen blasting in the shaft, not only the sinking velocity is raised but also the safety of the freezing pipe is ensured. Criterions of the failure, the strength and the displacement are given in this paper. The values of the criterions can forecast the safety of the freezing pipe. |
