| Abstract: | As the opportunity of cemented back filling promoted in Wushan Copper Mine, the writers positive discovery the ways of sublevel pillars recycling based on current mining method and equipment. Through changing the backstoping sequence, optimizing the cemented filling process, adjusting the thickness of ore pillars, the double sublevel pillars recycling difficulties are solved; and en- sure safety production, the ore recovery rate is improved to more than 80%. |
