堆浸浸出率灰色系统GM(1,1)模型的建立及预测

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。

Establishment and Forecasting of Grey System GM(1,1) Model for Heap Leaching Rate

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 processing and economy that have grey characteristics.
