Modified tailing mud double-liquid slurry and slurrying and grouting process
The invention discloses modified tailing mud double-liquid pulp and a pulping and grouting process. The modified tailing mud double-liquid slurry is composed of, by weight, 1 part of cement, 1-3 parts of tailing mud and 1.6-4 parts of water, the ratio of the mass of the water to the sum of the mass of the cement and the mass of the tailing mud, namely the water-solid ratio, is 0.8-1: 1, and the addition amount of the water glass is 1%-3% of the sum of the mass of the cement and the mass of the tailing mud. The modified tailing mud double-liquid slurry disclosed by the invention not only has excellent performance in multiple aspects such as groutability, stability, impermeability and durability, but also reduces consumption of natural clay materials by the slurry, saves land resources, further saves engineering cost, effectively combines mine curtain grouting engineering and solid waste product treatment, and is beneficial to environmental protection. A new solution is provided for mine tailing slime treatment, the dam break risk of a tailing pond is reduced, and comprehensive utilization of slime is achieved.
本发明公开了一种改性尾矿泥双液浆及制浆注浆工艺。该改性尾矿泥双液浆由水泥、尾矿泥、水和水玻璃组成，按重量份数计，所述水泥为1，尾矿泥为1～3，水为1.6～4，且水的质量与水泥和尾矿泥两者质量之和之比即水固比为0.8～1:1，水玻璃的添加量为水泥与尾矿泥质量之和的1％～3％。本发明的改性尾矿泥双液浆，不仅具有可注性、稳定性、防渗性、耐久性多方面优良性能，同时减免浆液对天然粘土料的消耗，节约土地资源，进一步节省工程成本，还将矿山帷幕注浆工程和固废产物处理有效结合，为矿山尾矿矿泥处理提供新的解决办法，降低尾矿库溃坝风险，实现矿泥的综合利用。
