摘　　要：根据内蒙古柴胡栏子金矿实际开采情况,采用三因素三水平正交试验法对采场结构参数进行优化,并结合三维有限元数值计算获取各因素的评判指标值。采用模糊数学理论和层次分析法建立目标相对优属度矩阵和权重矩阵,最后综合评判选出适宜方案。结果表明,柴胡栏子金矿深部开采的适宜采场结构参数为:采场长度40 m,间柱宽度10 m,顶柱厚度5 m。According to the actual mining situation in Chaihulanzi Gold Mine in Inner Mongolia,an orthogonal array testing with three factors and three levels was conducted to optimize the stope structural parameters.Then,the evaluation indicator of each factor was obtained in combination with three-dimensional finite element numerical calculation.After that,relative superiority matrix and weight matrix were established for the target by using fuzzy mathematics theory and analytic hierarchy process.An appropriate scheme was finally selected based on the comprehensive evaluation.The results show that an appropriate stope at the deeps of the Chaihulanzi Gold Mine should be 40 m long,with pillars 10 m in width and crown pillar 5 m in thickness.
