  • 基于多因素层次分析法的金山金矿采场结构参数优化及应用……程文文,侯俊,张小瑞
  • 摘 要:针对金山金矿采用浅孔房柱采矿法开采中存在生产能力较低、贫损指标不理想等问题,开展了底盘漏斗中深孔充填采矿法试验研究。基于多因素层次分析法对采场结构参数进行优化,得到最终参数为:采场长度60 m,采场宽度30 m,底盘漏斗间距7 m,斗井高度7 m。现场工业试验表明:矿块生产能力286 t/d,矿石贫化率8.15 %,技术经济效果良好,值得推广。

    Optimizationof the stope structural parameters in Jinshan Gold Mine based on multi-factoranalytic hierarchy process and its application……Cheng WenwenHou JunZhang Xiaorui

    AbstractThe short-hole room-and-pillar mining method in Jinshan Gold Mine has poorproduction capacity and unsatisfactory dilution and loss index,so experimentalresearch was carried out on the mining method of medium-long hole blasting andbackfilling with bottom funnels.The stope parameters are optimized based onmulti-factor analytic hierarchy process and the final parameters determined areas follows: stope length is 60 m,width is 30 m,interval between bottom funnelsis 7 m,funnel neck height is 7 m.The field industrial test achieved acomprehensive production capacity of 286 t/d for the stope and an ore dilutionrate of 8.15 %,indicating good technical economic effect.The achievements areworth promotion.
