| 摘 要： | 研究采空区稳定性评价新方法或模型对于提高采空区稳定性状况评判的可靠度、保证地下矿山的生产安全具有重要意义。选取工程地质环境、岩体质量、采空区几何参数和围岩应力四方面的因素作为采空区稳定性的主要影响因子，构建了地下矿山采空区稳定性评价指标体系。基于功效系数法原理，采用三标度改进层次分析法确定各评价指标的权重系数，建立了采空区稳定性评判分级新模型。将所建立模型运用到盘龙铅锌矿采空区稳定性评价研究，评判结果与工程实际相吻合，验证了基于功效系数法的采空区稳定性评判分级模型的适用性和可靠性，为采空区稳定性评价提供了一种新方法。

| Abstract: | It is of great significance to develop a new model of goaf stability evaluation for improving the reliability of goaf stability evaluation and ensuring the safety of underground mine. The evaluation indices for goaf stability was built through selecting four factors as the main influencing factor which includes engineering geological environment, rock mass quality, geometric parameters and surrounding rock stress of goaf. Based on the principle efficacy coefficient method, using the three-scale improved analytic hierarchy process (AHP)to calculate the weight coefficient of evaluation indices, a new model of goaf stability evaluation was established. Then the model was employed to evaluate the goaf stability in Panlong lead-zinc underground mine. The evaluation results were in good agreement with the actual situation, which verified the feasibility and reliability of the newly established evaluating model based on efficacy coefficient method. Thus the study provides a new approach for goaf stability evaluation. |
