Mine tailing filling additive and preparation method thereof, filling material and filling slurry
The invention discloses a mine tailing filling additive and a preparation method thereof, a filling material, filling slurry and a preparation and use method thereof, which belong to the technical field of mine filling. The filling additive comprises the blast furnace water-quenched slag, the Fe element content in the blast furnace water-quenched slag is A, the Fe<3+> content in the blast furnace water-quenched slag is B, alpha=(B/A)*100%, alpha is smaller than or equal to X%, and the filling additive and tailings are jointly mixed to form the filling material in the later period, by limiting the content of Fe<3+> in the blast furnace water-quenched slag in the filling additive, full release of active components in the filling material is ensured, and further, the solidification speed and the strength of the filling material containing the additive are improved, so that under the condiction that the filling material is ensured to have excellent strength performance, the addition amount of cement in the additive is reduced, so that the final filling material product is relatively good in filling performance and relatively low in production cost.
本发明的一种矿山尾砂充填添加剂及其制备方法、充填料、充填料浆及其制备、使用方法，属于矿山充填技术领域；本发明中所述充填添加剂中包括高炉水淬渣，所述高炉水淬渣中Fe元素含量为A，高炉水淬渣中Fe3+含量为B，其中α＝(B/A)*100％，所述α≤X％，由于后期充填添加剂会与尾砂共同混合形成充填料；本发明中通过限制充填添加剂中高炉水淬渣Fe3+的含量，保证充填料中活性成分的充分释放，进而有利于提高含有该种添加剂充填料的凝固速度以及充填料的强度，从而实现在保证充填料具有优异强度性能的情况下，减少添加剂中水泥的添加量，使得最终的充填料产品充填性能较好且生产成本较低。
