中文摘要: 矿山露天开采中后期会转入地下开采,而露天转地下开采过程对露天边坡稳定性的影响将直接决定着矿山的安全生产。因此,研究露天转地下开采边坡的稳定性,并对其进行评价具有非常重要的实用意义。结合现场调研情况和实际工程,基于灰色多层次分析评价理论构建出露天转地下开采边坡的灰色多层次分析评价模型。研究表明:海南某铁矿露天转地下开采边坡基本稳定,需要采取一定的防治措施,结果与实际情况吻合,因而灰色多层次分析评价模型能较好地对露天转地下开采边坡进行稳定性评价,具有一定的实用性和可行性。
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.
