【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。
[Abstract]:The production safety, mining capacity, ore loss rate and comprehensive economic benefit are all affected by mining methods. Therefore, it is very important to choose the mining method correctly or not. In the conventional mining method selection, most of them are influenced by the subjective factors of the selector, and most of them are influenced by the experience analogy method. The grey relation theory is used to evaluate the determination and quantity of several schemes obtained from the primary election, and the best mining scheme is finally selected.
