摘　　要：在矿山胶结充填中，传统的胶结材料是水泥，一般占充填成本的60％～80％。济钢第三炼铁厂的高炉水渣的室内试验表明：该厂的高炉水渣磨细具有较好的胶结性能，完全可替代部分水泥进行胶结充填。工业试验证明：高炉水渣可以替代40％～50％的水泥，充填成本可降低19．4％～24.2％。本文介绍了高炉水渣在张马屯铁矿的试验情况，描述了其工艺流程及可望取得的效益。In cemented filling mining, cement is the traditional cementing material and takes 60 % ~ 80%of the total filling cost universally. The laboratory tests for blast-furnace slag of the third smeller of Jinan Iron&. Steel Group show that ground slag has a better cementing property and can replace parts of cement for cemented filling material. The field trial shows that the slag can replace 40%~50% of the cement and the cemented filling cost can be reduced by 19. 4% ~ 24.2 %. This paper introduces the tests of blast-furnace slag atZhangmatun Iron Mine, describes the process flowsheet and the expected benefits that can be obtained.
