Preparation method of lead-zinc ore tailing sand filling body cementing material
The invention discloses a preparation method of a lead-zinc ore tailing sand filling body cementing material. The preparation method of the lead-zinc ore tailing sand filling body cementing material comprises the following steps: 1) spraying a polyhedral oligomeric silsesquioxane solution onto lead-zinc ore tailing sands with the particle size of below 100 [mu]m, and then precipitating to obtain modified tailing sands; and 2) mixing the modified tailing sands, cement, a polycarboxylate admixture and water to prepare the lead-zinc ore tailing sand filling body cementing material. The treatmentmethod ensures the good fluidity of the lead-zinc ore superfine tailing sand filling body cementing material, and effectively controls the setting time of a filling body, and the strength of the set filling body can also meet the filling requirement.
本发明公开了一种铅锌矿尾矿砂充填体胶凝材料的制备方法。这种铅锌矿尾矿砂充填体胶凝材料的制备方法，包括以下步骤：1)向粒径小于100μm的铅锌矿尾矿砂喷淋笼型聚倍半硅氧烷溶液，然后沉淀，得到改性尾矿砂；2)将改性尾矿砂、水泥、聚羧酸盐外加剂和水混合，制得铅锌矿尾矿砂充填体胶凝材料。通过本发明的处理方法，可以在保证铅锌矿超细尾矿砂充填体胶凝材料良好流动度的同时，使充填体的凝结时间得到有效控制，凝结后的充填体强度也能达到充填要求。
