| Abstract: | The principles and algorithms for establishment of the rules and formula on ore grade estimation by means of combination of qualitative and quantitative factors, automatically grouping and determination of relative importance of control points data, elimination of redundant data and factors on the basis of variable precision rough set theory are described. The rules and formula of ore grade estimation under any complicated conditions can be accurately found out by the proposed method, and the results are precisely consonant with the practice. |
