Filling material doped with red mud, desulfurized gypsum and slag and preparation method thereof
The invention discloses a filling material doped with red mud, desulfurized gypsum and slag and a preparation method thereof, and belongs to the technical field of filling materials. The filling material is red mud, slag, desulfurized gypsum and bone glue with the ratio of 3-5 and the mass concentration of 80%-84%, and filling slurry can be obtained by pouring water into the material, the solid waste red mud and the desulfurized gypsum are compounded to excite the slag, the coal gangue is used as the aggregate to prepare the paste filling material, on the basis of controlling surface subsidence, the recovery rate of mineral resources can be increased, and the production cost can be reduced. Meanwhile, a large amount of solid waste is utilized, pollution to the environment is reduced, and good economic and environmental benefits are generated.
一种掺有赤泥、脱硫石膏与矿渣的充填材料及其制备方法，属于充填材料技术领域。充填材料为赤泥、矿渣与脱硫石膏，骨胶比为3～5，质量浓度为80％～84％，将水倒入材料中可得到充填料浆，本发明利用固废赤泥和脱硫石膏复合激发矿渣，并以煤矸石作为骨料制备膏体充填材料，能够在控制地表沉陷的基础上，提高矿产资源的回采率，恢复矿区土地使用价值，同时大量利用了固体废物，减少了对环境的污染，产生了良好的经济和环境效益。
