基于改进后的灰色聚类分析理论的采矿方案优选

Optimizations of mining schemes based on improved grey cluster and grey forecasting model

采矿方案选择受多种因素的影响,而这些影响因素之间的量纲与物理意义差别较大,为此,参考灰色效果测度理论,对原有的灰色聚类理论进行了改进,避免了主观性和指标量纲差异的影响。利用改进后的灰色聚类理论对各备选采矿方案进行了各级聚类系数计算及评价,使采矿方案的评价选择更加科学合理。实践证明,改进后的灰色聚类理论科学可行,可以在类似的方案优选中推广应用。

The selection of mining schemes are affected by many factors among which dimension With the physical meaning are greatly different, as result in gray effect measure theory was refer- enced, the original gray cluster has been improved, which subjec- tivity and dimensional differences among factors were avoided. The improved gray cluster was applied to calculate clustering coef- ficients at all levels and evaluate to each alternative mining scheme, making the evaluation and selection of the mining schemes to be more scientific and rational, it＇s proved that the im- proved gray cluster are scientific and feasible, can be applied in similar schemes optimization.
