Mineral resources are the material basis of national economic development and therefore, it is very important to set up a scientific and practical model for the technical and economical evaluation of iron resource exploitation and utilization. The collected data of iron resource exploitation and utilization from 1994 to 2001 was processed by grey relevance analysis method in grey system theory. The coefficient of relevance of the technical and economical indexes of the mining beneficication and metallurgy of iron ore resources to the optimum indexes was induced. As a result, a general change condition of the technical and economical indexes of iron ore resource in 1994~ 2001 was obtained.

矿产资源是国民经济发展的物质基础 ,建立科学实用的铁矿资源开发利用技术经济评价模型十分重要。通过收集 1994~ 2 0 0 1年的铁矿资源开发利用的数据资料 ,利用灰色系统理论中的灰色关联分析方法进行处理 ,得到了铁矿资源的采选冶技术经济指标与最优指标的关联系数 ,从而得到了铁矿资源 1994~ 2 0 0 1年技术经济指标的总体变化状况

A model GM(1,1) for heap leaching rate was established by applying the theoretical principles and modelling process of grey syetm theory.It was used in grey forecasting for the leaching rate of a laboratory simulation test on an uranium ore and "residual test method" and "grey relevance degree test method" were used for checking.The results show that GM(1,1) model has high accuracy of fercasting and is suitable for the simulation control and prediction analysis of original data series such as geology,mining,mineral...

应用灰色系统理论的数学原理及建模过程,建立了堆浸浸出率的GM(1,1)模型。应用该模型对某铀矿石室内模拟试验的浸出率进行灰色预测,采用“残差检验法”和“灰关联度检验法”进行检验。结果表明,GM(1,1)模型的预测精度高,适合于具有灰色特征的地质、采矿、选矿、经济等原始数据序列的模拟控制和预测分析。
