摘　　要：矿山的生产安全、采矿能力、矿石的贫损率和综合经济效益等这一系列的指标都受采矿方法的影响。因此采矿方法选择的正确与否非常重要,在常规的采矿方法选择中,多数用经验类比法,受选择者主观因素的影响,具有一定局限性。采用灰色关联理论对初选得出的几种方案既定性又定量的评价,最终优选出最佳采矿方案。以河南某金矿为例,根据现场实际情况初步提出方案Ⅰ、Ⅱ和Ⅲ,计算得出3种供选采矿方案的关联度分别为0.787,0.754和0.860,因此第Ⅲ种方案最优。A series of indicators of mine were affected by mining method, such as production safety, mining capacity, ore dilu- tion rate and comprehensive economic benefits. Therefore, the selection of mining method was very important. However, in the general selection of mining method, most preferred to use experience analogy, and the decision highly depended on the personal experience which had certain limitations. The grey relation theory was used to qualitatively and quantitively evaluate the prima- ry schemes. Finally, the optimal mining scheme was selected. Taking a gold mine in Henan as an example, three schemes were proposed preliminarily according to the actual situation of project. Then, the correlations of the three methods were calculated as 0.787, 0.754 and 0.860 respectively. So the third scheme was determined to be the best.
