摘要
武山铜矿长期以来采用长江江砂充填，因长江禁止采砂，砂源供应无保障，且成本很高，虽采用了部分分级尾砂充填，还远远不能满足生产需要，为此武山铜矿采用掘进废石磨砂来弥补充填砂源不足．取得了显著效果。
Using sand of Changjiang river to fill for a long time in Wushan Copper Mine. But because quarry in Changjiang river is forbidden, the source of sand can not be ensured. EVen if part of classified tailings are used, the filling materials still can not meet the need of production. The milled waste stone are used to remedy a shortage of filling materials, and the effect is notable.
