| Abstract: | The paper introduced the design of the freezing plan for alluvium from 518 m to 524 m in Zhaogu No.1 Mine of Jiaozuo Mining Area. After the calculation formula, method, basic parameters of the freezing depth, freezing wall thickness and safety excavation section height, the freezing hole arrangement method, freezing technology, optimization, flac- 3D numerical value analysis of freezing wall stability, prediction of freezing wall formation and comprehensive analysis method, the rational freezing plan and the rational main parameters provided in the paper were scientific rational. The freezing wall strength and stability performances can fully meet the requirements of freezing mine shaft sinking in special thick alluvium. |
