Filling cementing material for cemented mine superfine tailings, preparation method of filling cementing material and method for cemented filling of tailings by using filling cementing material
The invention provides a filling cementing material for cemented mine superfine tailings, a preparation method of the filling cementing material and a method for cemented filling of the tailings by using the filling cementing material. The filling cementing material for cemented mine superfine tailings comprises the following raw materials in percentage by mass: 5%-40% of cement, 50%-80% of granulated blast furnace slag micropowder, 5%-25% of dihydrate gypsum, 2%-10% of quick lime and 0.5%-2% of an exciting agent. The preparation method of the filling cementing material for the cemented mine superfine tailings comprises the following steps: drying and mixing the raw materials to obtain the filling cementing material for the cemented mine superfine tailings. The method for cemented filling of tailings by using the filling cementing material for cemented mine superfine tailings comprises the following steps: mixing and stirring the mine superfine tailings, the filling cementing material for cemented mine superfine tailings and water. According to the filling cementing material for cementing the superfine tailings of the mine, the early strength of a filling body is high, and the later strength is stable.
本申请提供一种胶结矿山超细尾砂的充填胶凝材料及其制备方法和使用其进行尾砂胶结充填的方法。胶结矿山超细尾砂的充填胶凝材料，其原料以质量百分比计算，包括：水泥5％‑40％、粒化高炉矿渣微粉50％‑80％、二水石膏5％‑25％、生石灰2％‑10％、激发剂0.5％‑2％。胶结矿山超细尾砂的充填胶凝材料的制备方法，包括：将原料干燥，混合，得到所述胶结矿山超细尾砂的充填胶凝材料。使用所述的胶结矿山超细尾砂的充填胶凝材料进行尾砂胶结充填的方法，包括：将矿山超细尾砂、所述胶结矿山超细尾砂的充填胶凝材料和水混合，搅拌。本申请提供的胶结矿山超细尾砂的充填胶凝材料，充填体早期强度高，后期强度稳定。
