某小型地下铁矿采矿方法选择

Selection of the Mining Method of a Small Underground Iron Mine

采矿方法对矿山生产规模、矿石损失率、贫化率、劳动效率、成本及安全等有很重要的影响。通过对某小型地下铁矿影响采矿方法选择的主要因素分析并对多种采矿方法进行比选,最终选择了矿山最适用的分段采矿法,并论述了分段采矿法的采场布置、采准、切割、回采等工艺,取得了较好的技术经济指标,对其他类似小型地下矿山具有一定的参考价值。

The influence of mining method to the factors of mining production scale,ore loss ratio,dilution rate,labor efficiency,production cost and safety is important.Taking a small underground iron mine as the study example,the affecting factors of the selection of mining method are analyzed,and the optimization selection of mining method of the mine is conducted,the most one that is suitable for the mine is obtained finally.Besides that,the process of stope layout,stope preparation,cutting,stoping of sublevel mining method are discussed in detail,and the ideal economical technical indicators are obtained by the practice of the mining area.The above discussion results can provide some reference for the other similar underground mines.
