Tailing comprehensive utilization goaf backfilling method
The invention discloses a tailings comprehensive utilization goaf backfilling method, and relates to the technical field of tailings treatment. The method comprises the steps that tailings are separated into first-stage tailings and second-stage tailings, and the particle size of the first-stage tailings is larger than that of the second-stage tailings; the secondary tailings are ground, and the particle size of the ground secondary tailings is smaller than 0.1-0.15 mm; preparing filling slurry; the ground secondary tailings are mixed with cement and water, then the primary tailings are added, and filling slurry is obtained after full stirring and mixing; the mass ratio of the secondary tailings to the cement is (1-1.5): 1, and the mass ratio of the primary tailings to the sum of the secondary tailings and the cement is (1-3): 1; and the goaf is backfilled with filling slurry. According to the method, the tailings are separated into the first-stage tailings and the second-stage tailings, the second-stage tailings are ground and then mixed with the cement, and therefore the mass ratio of the tailings to the cement is increased, the comprehensive utilization effect of the tailings is greatly improved, and the overall utilization rate of the tailings is increased.
本发明公开了一种尾砂综合利用采空区回填方法，涉及尾矿处理技术领域。本发明包括将尾砂分选为一级尾砂和二级尾砂，且一级尾砂的粒径大于二级尾砂；对二级尾砂进行研磨，且研磨后的二级尾砂粒径为粒径小于0.1～0.15mm；制备填充浆料；将研磨后的二级尾砂与水泥、水进行混合，再加入一级尾砂，充分搅拌混合后得到填充浆料；二级尾砂与水泥的质量比为1～1.5：1，一级尾砂与二级尾砂和水泥的总和的质量比为1～3：1；使用填充浆料对采空区进行回填填充。本发明通过将尾砂分选为一级尾砂和二级尾砂，并将二级尾砂进行研磨后再与水泥进行混合，从而提高尾砂与水泥间的质量比，大大的提高了尾砂的综合利用效果，使得尾砂的整体的利用率的得到提高。
