摘要
根据宜春钽铌矿的现场实际生产资料,结合品位指标优化的理论和原理,运用ORIGIN和MATLAB计算机软件,采用数理统计的方法建立了品位指标优化中必需的体重模型、储量系数模型、平均品位模型和选比模型,其建模步骤为:建立矿石取样品位频数直方图;建立品位分布密度函数数学模型;建立以积分求不同品位指标下的平均品位和储量的数学模型。以宜春钽铌矿为例,介绍了各个模型建立的具体方法,采用已建立的这些模型,大大降低了后续品位指标动态优化的计算工作量,并且计算数据准确,为品位指标的整体动态优化提供了基础。
Based on the production of Yichun Ta-Nb ore on-site,combined with the theory and principle of quality indicators for optimization,using ORIGIN,and MATLAB computer software and the method of mathematical statistics,a quality indicator in the optimized models was established,including the needed weight model,reserve coefficient model,an average grade model and the selection ratio model.The steps of the establishment of the models contained the establishment of grade ore sampling frequency histogram,mathematic...
