合理入选品位整体动态优化

United Dynamic Optimization Study on the Rational Beneficiation Feed Grade

采用系统工程理论和方法，建立了品位指标、储量、平均品位、贫化率、损失率、入选品位等主要技术指标与矿山效益目标之间的动态关系模型，并运用多目标决策技术对这些指标进行整体动态的优化．优化结果应用于矿山生产取得显著的经济效益．如歪头山和梅山铁矿每年各增收利税约 １０００万元．

Applying the theory and method of system engineering, the dynanic relation models about mine benefit object and main technical indexes, including industrial indexes of ore deposit, reserves average grade,loss rate dilution rate and beneficiation feed grade, have been built. Based on these models, the multi-object decision technique has been used to optinzed these indexes dynamically. Asignificant economic benefit has been gotten by using the research result, for example, a added profit of 10 million RMB per year was gotten in Waitoushan Iron Mine and Meishan Iron Mine.
