大直径深孔空场嗣后充填采矿法开采隔离中段的研究和实践

Research and Practice of Mining Isolation Section by Large Diameter Deep Hole Open Stope Filling Mining Method

阿舍勒铜矿600m以下采用大直径深孔空场嗣后充填采矿法,每隔50m一个采区中段,在上下采区中段采充后,隔离中段的开采成为采矿工作的难点。通过对可能方案进行对比分析,确定与实施可行的方案,并对方案效果进行总结,认为该方案增加此方法的适用范围,解决了隔离中段采矿困难,安全、经济、可靠,可在类似矿山上进行推广。

Six hundred meters below the Ashele copper mine use large diameter deep hole open stope filling miningmethod, there is a middle area every fifty meters, after mining and filling on the middle of upper and lower mining ar-ea upper and lower filling mining area, the exploitation of the isolated middle is a difficult point in the mining work.Through comparative analysis of the possible solutions, feasible solution was determined and implemented, the effectof the program was summarized that the program increased the scope of this approach, solved the difficulties of min-ing middle isolation, which is safe, economic, reliable, and can be popularized in similar mines.
