Filling tailing curing agent containing copper smelting slag
The invention relates to a filling tailing curing agent containing copper smelting slag, the curing agent is prepared by uniformly mixing the following raw materials in percentage by mass: 30-70% of copper smelting slag micro powder, 10-30% of S95 mineral powder, 5-20% of desulfurized gypsum, 5-25% of Portland cement clinker micro powder and 1-3% of anhydrous sodium sulphate, and drying until the water content is lower than 1%. The obtained curing agent is stable in working performance, high in early strength, good in fluidity and free of volume shrinkage after being cured, and complete roof contact of the filling body can be achieved.
本发明涉及一种含铜冶炼渣的充填尾砂固化剂，该固化剂由下述质量百分比的原料混合均匀后，经烘干至含水率低于1%制得：铜冶炼渣微粉30%~70%，S95矿粉10%~30%，脱硫石膏5%~20%，硅酸盐水泥熟料微粉5%~25%，元明粉1%~3%。本发明所得固化剂工作性能稳定，早期强度高，流动性好，固化后无体积收缩，可实现充填体的完全接顶。
