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 accurately evaluate the stability of underground mined-out area, the main factors affecting the stability of mined-out area are determined by analyzing the influencing factors of the stability of the mined-out area, and the geological, hydrological, environmental and geometric parameters of the mined-out area are determined. District stability evaluation index system. Comprehensive weighting method is used to determine the comprehensive weight of evaluation index. Combined with the fuzzy matter element theory, the fuzzy matter-element evaluation model of the stability of the gob area is constructed. The correlation degree is used to represent the evaluation result. The comprehensive evaluation of the stability of goafs in an underground metal mine shows that this method can be used to analyze the stability of underground goafs.
