摘要:
为确定某银矿的最佳采场结构参数,使该矿开采方案的安全性及经济性最优,构建了Vague-RSM-AFSA模型对采场结构参数进行优化。采用中心复合试验法设计了15个采场结构参数方案,并对各方案进行了数值模拟计算,选取了采场顶板最大沉降位移、间柱最大水平位移、采切比和矿石损失率作为评价指标。基于Vague理论计算了各指标权重及中心复合试验各方案的优越度,采用响应面法(RSM)建立了中心复合试验各方案采场结构参数与优越度的响应面模型,运用人工鱼群算法(AFSA)对优越度响应面模型寻优,得到最佳采场结构参数:采场高度为20 m,采场长度为32.8 m,间柱宽度为16.1 m,方案优越度为0.2631,高于中心复合试验中的最大优越度(0.2271),寻优结果与数值模拟验证结果误差为0.0037,表明Vague-RSM-AFSA模型具有良好的寻优能力及较高的准确性。
