| Abstract: |
| Xinjiang thicker, an iron ore body cover rock when bottomless pillar caving method is adopted to improve the operation, the effect of stope roof caving is poor, can lead to stress deformation of roadway is serious, or fall after surface subsidence does not reach the designated position, lead to geological disasters such as landslide, landslide. Based on rock mechanics test, therefore, for modeling the required mechanical parameters such as elastic modulus, poisson"s ratio, with the aid of finite element analysis software ANSYS, respectively set up thick overburden rock model, the model of roadway, orebody model, and simulation of initial ground stress, determine caving for late model of excavation sequence, choose the reasonable scheme to provide reliable technical guidance and reference. |
