| Abstract: |
| In order to avoid the goaf caving cause a harm to production buildings of the surface of the mine. According to the characteristics of the ore body and the present situation of mine production, classified tailings are used to carry out the management of the goaf. The stress and displacement of the surrounding rock before and after the goaf filling and the plastic zone were analyzed by FlAC3D. The simulation results show that classified tailings can effectively reduce the displacement of surrounding rock and improve the stress redistribution and maintain mine safety. |
