摘要
根据凡口铅锌矿磨砂充填生产中存在的问题,以磨砂试块强度试验结果作为制备系统改造和完善的依据,并确定了料浆以高浓度输送和最佳的灰砂配比,从而解决了生产难题,在应用中获得了显著的经济效益。
Based on strength test of cemented milled sand,the optinum transmitting density and cement to sand ratio are deterined for the fill preparation system updating,By using the updated system,the production problem is solved sucessfully.
