摘　　要：为提高地下金属矿山采空区危险性辨析的客观准确性,针对地下金属矿山采空区评价体系的多元、复杂及模糊特性,将改进的模糊层次分析法(FAHP)运用于采空区危险性辨析,引入3标度法、模糊一致矩阵及和行归一法确定各辨析指标的综合权重,不但增加了采空区危险性辨析的客观可靠性,而且避免了一致性检验。在复合模糊物元理论的基础上,建立地下金属矿山采空区危险性辨析指标体系,构建了基于改进FAHP-复合模糊物元的地下金属矿山采空区危险性辨析模型,确立了基于该方法的采空区危险性等级量化标准。将该法运用于某地下金属矿山采空区危险性辨析,结果表明,该方法可有效实现采空区危险性辨析和分级。In order to enhance the objective and accurate goaf risk discrimination for the underground metal mine,the paper has proposed an improved fuzzy analytic hierarchy three-scale processing（FAHP for short） method in reference to the fuzzy consistent matrix and rectified normalization method.Its successful application can not only increase the objective reliability of the goaf area risk discrimination,but also can make the consistency test redundant.To increase its evaluation efficiency,we have established a risk discrimination index system for the goaf of the underground metal mine based on a large number of references,at the same time we have also introduced a fuzzy complex element theory into the method.In our proposed model,we have first of all constructed the priority assessment matrices,and,then,transformed the priority matrices into those with fuzzy consistency so as to formulate the comprehensive weights about all discrimination indexes,and finally worked out the correlation coefficients.The quantitative standard of the goaf hazard ranks,including four hazard ranks： the extremely dangerous,highly dangerous,generally dangerous and low-level dangerous,has also been established by the improved FAHP-fuzzy complex element method.Successful application of the method shows that the improved FAHP-fuzzy complex element is highly feasible for the target of risk discrimination and classification in the goaf risk evaluation.It can serve as the decision-making reference to the goaf-mining management in the actual mining practice.
