【摘要】：礦山的生產(chǎn)安全、采礦能力、礦石的貧損率和綜合經(jīng)濟效益等這一系列的指標都受采礦方法的影響。因此采礦方法選擇的正確與否非常重要,在常規(guī)的采礦方法選擇中,多數(shù)用經(jīng)驗類比法,受選擇者主觀因素的影響,具有一定局限性。采用灰色關(guān)聯(lián)理論對初選得出的幾種方案既定性又定量的評價,最終優(yōu)選出最佳采礦方案。以河南某金礦為例,根據(jù)現(xiàn)場實際情況初步提出方案Ⅰ、Ⅱ和Ⅲ,計算得出3種供選采礦方案的關(guān)聯(lián)度分別為0.787,0.754和0.860,因此第Ⅲ種方案最優(yōu)。
[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. Taking a gold mine in Henan province as an example, schemes 鈪，
