摘要
为准确评价地下矿山采空区的稳定性,通过分析采空区稳定性的影响因素,确定采空区的地质、水文、环境及几何参数为采空区稳定性的主要影响因素,建立采空区稳定性评价指标体系。采用综合集成赋权法确定评价指标综合权重,结合模糊物元理论,构建采空区稳定性模糊物元评价模型,用关联度表示评价结果。某地下金属矿山采空区稳定性综合评价结果表明,该方法可用于地下采空区的稳定性分析。
In order to evaluate the stability of goaf accurately, through analyzing the factors affecting the stability of goaf, the geological, hydrological, environmental and geometric parameters of goaf were identified as the main factors that affect the stability of goaf. A stability evaluation index system was estab- lished. Weights of the evaluation indexes were obtained using the integrated weight method. A fuzzy matter-element evaluation model of goal was built. Evaluation results of a certain underground metal mine goaf stability show that this method can be used for the stability analysis of underground mine goaf.
