摘要
应用灰色系统理论的数学原理及建模过程，建立了矿石产量的ＧＭ（１，１）模型，应用该模型对陕西省某金矿每季度矿石产量进行灰色预测，采用“残差检验法”和“滚动检验法”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、选矿等原始数据序列的模拟控制和预测分析。
This paper sets up gray system GM(1,1)model for ore yield by using the mathematical principle and the establishment steps of gray system theory,a gray prediction for ore yield per quarter of a gold mine in Shaanxi province has been completed with the help of “remains value examine method”and“rolling examine method”.The result indicates that the prediction of a GM(1,1) model is very precise and can be used in simulation control and prediction analyses for original data series of geology,mining,ore dressing and so on which have gray characteristics.
