For determining support parameters in an advancement project of the secondary shaft of Comica Mining's Kamoya copper-cobalt mine in the DRC, 25 sets of testing schemes were designed by using Box-Behnken based on the engineering geological conditions. After numerical analysis with FLAC^3D, the mechanical response characteristics under various support conditions were obtained. In combination with technical and economic requirement, analysis hierarchy process and principal component analysis were adopted for the combined weighting of nine selected indices, including advancement cost, maximum tensile stress among others, and then a comprehensive evaluating model was established for the parameters of shaft support. A multivariate second-order regression prediction equation was then obtained with the comprehensive scores as response indicators, and shaft support parameters as the variables. It is found that shaft is supported with 35 anchor bolts with thread length of 2.5 m arranged in horizontal direction, with spacing of 1 m in vertical direction, as well as the concrete lining with strength grade of C35, and the best comprehensive benefits can be obtained.

针对刚果（金）科米卡矿业卡莫亚铜钴矿副井开拓建设工程中支护参数优选问题，结合工程地质条件，采用Box-Behnken方法设计了25组试验方案。应用FLAC^3D进行数值分析，获得了不同支护参数条件下的力学响应特征，结合技术经济要求，选取开拓成本、最大拉应力等9个指标，利用层次分析法及主成分分析法组合赋权各评价指标，提出了竖井支护参数综合评价模型。以规范化综合评分为响应指标、竖井支护参数为变量，构建了多元二阶回归预测方程。结果表明，竖井支护优化参数为：水平方向锚杆根数35、锚杆竖直方向间距1 m、锚杆长度2.5 m、衬砌混凝土强度等级C35，此时综合效益最大。
