Cementing material suitable for tailings of different grades, filling body, preparation method and application process
The invention discloses a cementing material adapting to tailings of different grades, a filling body, a preparation method and an application process, and relates to the field of mine filling. The cementing material comprises the following components in parts by weight: 50-80 parts of blast furnace slag micropowder; 10-20 parts of steel slag powder; 10 to 20 parts of cement clinker; 5 to 10 parts of gypsum; 3-8 parts of lime and 1-3 parts of an early strength agent. The invention further discloses a filling body which comprises 8-15 wt% of the cementing material and 85-92 wt% of fine tailings. In the fine tailings, the overflow fine tailings account for 0-100 wt%, and the graded fine tailings account for 0-100 wt%. The preparation method of the filling body comprises the following steps: S1, preparing the cementing material; s2, fine tailings are screened; and S3, preparing the filling body. The filling body is applied to the field of mine filling. According to the technical scheme, the utilization rate of the tailings can be increased, the capacity pressure of the tailings pond is reduced, and meanwhile the application range of the cementing material to the tailings with different particle sizes is widened through preparation of the cementing material.
本申请公开了适应不同级配尾砂的胶凝材料、充填体、制备方法及应用工艺，涉及矿山充填领域，包括以下按重量份数计的组分：高炉矿渣微粉50～80份；钢渣粉10～20份；水泥熟料10～20份；石膏5～10份；石灰3～8份以及早强剂1～3份。本申请还公开一种充填体，包括上述的胶凝材料8～15wt％以及细尾砂85～92wt％；所述细尾砂中，溢流细尾砂占0～100wt％，分级细尾砂占0～100wt％。上述充填体的制备方法，包括以下步骤：S1、制备胶凝材料；S2、筛选细尾砂；S3、制备充填体。上述充填体在矿山充填领域的应用。本申请技术方案不仅可以提高尾砂利用率，减少尾矿库容量压力，同时胶凝材料的制备扩大了胶凝材料对于不同粒径尾砂的适应范围。
