| 中文摘要: |
| 运用灰色理论,以焦家金矿床矿体品位、厚度代表矿化的白化值,经过数据生成处理,建立了矿体品位、厚度灰色GM(1,1)模型。通过残差、后验差、关联度检验,研究了模型的可靠性,对影响预测模型精度的因素进行了分析,并提出了提高模型精度的方法;通过GM(1,1)模型预测,焦家金矿床Ⅰ,Ⅲ矿体金矿化强度自浅部向深部逐渐增强,Ⅱ号矿体品位自浅部向深部逐渐增高,但厚度有逐渐减小的趋势,总体矿化强度不及Ⅰ,Ⅲ矿体。 |
| 英文摘要: |
| The results calculated according to the fractal theory show vertical variation in mineralization and the extension to depth of ore bodies is predicted on basis of the results of gray GM(1,1) model.The prediction is that mineralization of ore body Ⅰ,Ⅲ is gradually intensified to depth and ore grade of ore body Ⅱ rises but becomes thin to depth and mineralization intensity is not as high as ore body Ⅰ,Ⅱ. |
