| Abstract: | The finite element analysis method is used to simulate the excavation of gate road in the upper slicing, mining of the upper slicing and excavation of gate road in the bottom slicing. The following conclusions can be drawn: rational layout location of gate road in the bottom slicing, stress distribution of the bottom slicing, displacement characteristics and breaking process of side coal wall of gate road in the bottom slicing; It is indicated by the behaviors experiment of concrete filled steel tube that this material has good plasticity and flexural capacity. In the practical project, it is proved that blot beam support technique of gate road in the bottom slicing has good supporting effect. |
