| Abstract: |
| When surface mining finished, mine will turn to underground mining, it influences the stability of surface slopes which will directly determine the safe production of mine. Therefore, it is significantly important to research and evaluate the stability of slope in transition from open-pit to underground mining. Combined with the field investigation and practical projects, evaluation model of grey multi-level analysis is constructed based on grey multi-level evaluation method. The results show that the slope in transition from open-pit to underground mining of certain iron mine is stable basically in accordance with reality, so it’s necessary to take some control measures. Then evaluation model of grey multi-level analysis can satisfactorily evaluate the stability of slope in transition from open-pit to underground mining with practicability and feasibility. |
