Method for preparing underground cemented filling material by fully utilizing fine-fraction gold tailings
The invention discloses a method for preparing an underground cemented filling material by fully utilizing fine-grained gold tailings. The method comprises the following steps: preparing cementing powder, wherein the cementing powder comprises the following components: 60-80.4 wt% of blast furnace water-quenched slag, 4-5 wt% of lime, 14.3-15.3 wt% of gypsum and 0.3 wt% of mirabilite; and mixing the cementing powder with gold tailings containing fine-fraction tailings according to a mass ratio of 1:(6-8), wherein the mortar concentration is 58-65%, and the particle size of the fine-fraction tailings is 0.038 mm or less. The method can be used for filling all tailings and filling fine-fraction tailings with the particle size of 0.038 mm or below, so that a cemented filling body has high strength; blast furnace water-quenched slag steelmaking byproducts and gypsum are desulfurized gypsum and are industrial byproducts, main raw materials are relatively low in price and relatively wide in source, and the total cost is relatively low; and the cement has high strength and can meet the requirements of mine production.
本发明公开了一种充分利用细粒级黄金尾矿制备井下胶结填充材料的方法，包括：制备胶固粉：所述胶固粉其成分包括高炉水淬渣60‑80.4wt％、石灰4‑5wt％、石膏14.3‑15.3wt％、芒硝0.3wt％；将胶固粉与含有细粒级尾砂的黄金尾矿按照1:6‑8的质量比混合，砂浆浓度58％‑65％；所述细粒级尾砂的粒径在0.038mm以下。本发明可用于全尾砂充填以及粒径为0.038mm以下的细粒级尾砂充填，使得胶结充填体具有较高的强度；高炉水淬渣炼钢副产品，石膏用脱硫石膏，为工业副产品，主要原材料价格相对低廉，来源比较广泛，总成本相对较低；胶结体强度比较高，能够满足矿山生产的需求。
