摘　　要：采场结构参数优化是一个多因素,多层次,多属性相互影响的系统工程。为了充分发挥数值模拟与多种不确定性分析方法的评价优势,提出了FLAC3D-AHP-TOPSIS紧密结合的联合分析法。以内蒙玉龙矿为例,运用FLAC3D分析了应力、位移在不同采场结构参数方案下的变化规律,将模拟结果与采场生产能力作为影响采场方案的评价指标,导入AHP-TOPSIS模型计算出各方案的理想逼近度,从而确定玉龙矿主采区最优采场结构方案,最后对优选方案进行了充填模拟验证和生产实践验证,达到了生产高效安全、经济合理的目标。The optimization on stope structure parameters is a systemic engineering with the interplay of multiple factors, levels and attributes. For taking full advantages of numerical simulation and various uncertainty analysis methods, a new conjoint analysis of FLAC^3D --AHP--TOPSIS was proposed. Taking Yulong Mine in Inner Mongolia as an example, the change rules of stress and displacement under different stope structure parameters were analyzed by FLAC^3D. Then, the simulated results and stope capacity, as the evaluation inde- xes of stope schemes, were leaded to the AHP--TOPSIS models to calculate the ideal approximation degree of each scheme, so as to determine the optimum scheme structure for main mining area. Finally, the filling simulation and pro- duction practice of optimum scheme were carried out, which realized efficient and safe production, as well as reasonable economy.
