Mine karst cave filling slurry and preparation method thereof
The invention discloses mine karst cave filling slurry and a preparation method thereof, belonging to the technical field of mine filling. The mine filling slurry is composed of, by mass, 30%-60% of red mud, 20%-40% of phosphogypsum, 10%-20% of fly ash and 5%-10% of a modifier. The mine filling slurry is synthesized by grinding the above materials, adding water and carrying out mixing. The mine filling slurry prepared in the invention is good in fluidity, wide in raw material source, relatively low in production cost and simple in technological process, the solidification time and strength of the mine filling slurry meet requirements, a large amount of red mud and ardealite industrial waste residues are consumed, and the mine filling slurry has important significance on energy conservation, emission reduction and environmental protection.
本发明公开了一种矿山溶洞填充浆料及其制备方法，属于矿山填充技术领域，矿山填充浆料有质量百分比30％～60％的赤泥、20％～40％的磷石膏、10％～20％的粉煤灰、5％～10％的改性剂组成；通过研磨加水混合合成，本发明制备的矿山填充浆料流动性好，原料来源广泛，生产成本较低，工艺过程简单，凝固时间和强度符合要求，大量消耗了赤泥和磷石膏工业废渣，对节能减排、保护环境有重要意义。
