摘要
广东高要河台金矿对急倾斜薄矿脉矿岩中等稳固的矿床开采技术条件 ,采用浅孔留矿法为主要采矿方法是合理的 ,而对一些厚度较大品位较高的矿体通常应用干式充填法回采。实践中发现放矿溜井的堵塞是妨碍干式充填法采场生产能力提高的重要原因 ,在应用人工间柱的同时 ,取消了出矿钢溜井 ,改用混凝土人工隔墙间出矿 。
It is reasonable to adope the short holl shrinkage stoping as the main mining method in Hetai Gold Mine in the mineral deposit techonologe mining conditions of steep dipping thin reef and orebody and wall rock middle stability.While,dry fill stopping is often used for the orebody of thicker width and higher grade.It is found that in the practice that blocked ore pass is the considerable reason hindering the through put of dry fill stoping. It has got better production effect applying the artifical buttress pillar and loading with the concrete artifical dam in stead of the ore steel pass while.
