姑山铁矿挂帮矿Ⅱ期开采方案设计

Mining Scheme Design of Gushan Iron Mine Hang for Ore Ⅱ Stage

根据姑山铁矿挂帮矿的实际条件,进行了Ⅱ期开采工程方案设计。从矿床开采顺序、采矿方法、通风、排水、充填、压气、移动界线等方面进行了设计与计算。设计方案满足开采要求,充分回收挂帮矿资源,增加矿石年产量,确保矿山稳产。

According to the actual conditions of the Gushan iron mine hang for ore, the Ⅱ stage mining scheme is designed. The mining sequence, method, ventilation, drainage , filling, compressed air, moving boundary are designed and calculated. The scheme can meet the production requirements, the hang for mineral resources can be fully recycled and the iron ore output is increased, to ensure the miner- al resources of the Gushan iron mine.
