Mine tailing filling additive and filling material
The invention discloses a mine tailing filling additive and a mine tailing filling material, and belongs to the technical field of mine filling. The filling additive comprises slag powder, cement, calcium powder, fly ash and steel slag powder. The additive comprises the following components in parts by mass: 60-65 parts of slag powder, 5-8 parts of cement and 2-5 parts of calcium powder; the mass part of the fly ash is 5-15 parts, and the mass part of the steel slag powder is 3-8 parts. The slag powder comprises a glass body, and the content of the glass body is not less than 60%. The content is based on that the slag is ground until the specific surface area is more than 400kg/m2. The additive can effectively improve the filling performance of a filling material product.
本发明的一种矿山尾砂充填添加剂、充填料，属于矿山充填技术领域；本发明中所述充填添加剂中包括矿渣粉、水泥、钙粉、粉煤灰和钢渣粉，添加剂中矿渣粉的质量份为60～65份，水泥的质量份为5～8份，钙粉的质量份为2～5份；粉煤灰的质量份为5～15份，钢渣粉的质量份为3～8份，所述矿渣粉中包括有玻璃体，所述玻璃体含量不少于60％，该含量是将矿渣磨细至比表面积400kg/m2以上后，上述添加剂可以有效改善充填料产品充填性能。
