摘　　要：极细粒级全尾砂的快速沉降和高浓度放砂及输送是国内外矿山充填中面临的主要问题,它是制约高浓度全尾砂胶结充填的技术难点。针对存在的问题,通过相关技术研究,比较系统地测定和分析了冬瓜山铜矿选厂所排全尾砂的快速沉降和水泥-全尾砂充填料浆在不同条件下的输送特性,将其研究成果应用于生产,使生产成本降低,全尾砂快速沉降与高浓度输送得以实现,各项相关技术指标均达到国际先进水平。Fasting sedimentation and high concentration transportation of minuteness full tailings slurry are primary problems in the world and it is the technical difficulty which restricts the high concentration cemented filling at present, Aim at existent problems and get across correlative technical researches, then tested and analysed sedimentation and transportation characteristics of full railings and cement-full tailings slurry in Dongguashan Copper Mine, and made appliances in practice. The production cost reduced, and fasting sedimentation and high concentration transportation of full tailings slurry realized, and all kinds of correlation technical indexes achieved advanced international level.
