Magnesium slag hazardous waste solidification treatment and tailing all-solid waste filling mining method
The invention provides a magnesium slag hazardous waste solidification treatment and tailing all-solid waste filling mining method, and belongs to the technical field of intersection of solid waste solidification treatment and filling mining methods. The method comprises the following steps: replacing cement clinker with magnesium slag hazardous waste to prepare a magnesium slag-based filling cementing material; then carrying out tests on strength of cementitious bodies and rheological properties of filling slurry with different gel-sand ratios and slurry concentrations; carrying out pore structure analysis on the cementitious body by adopting a mercury injection instrument method; according to the test and test results, establishing the relationship between the cement strength, the slurry rheological parameters and the most probable pore size of the cement and the mortar-sand ratio and the relationship between the most probable pore size of the cement and the slurry concentration; and finally, establishing and solving an optimization model of the filling slurry to obtain optimized parameters of the filling slurry. By means of the method, all-solid-waste green filling mining is achieved, the economic and environment-friendly benefits of filling mining are improved, and a way is explored for recycling, reduction and harmless treatment and high-value utilization of magnesium slag hazardous waste.
本发明提供一种镁渣危废固化处置以及协同尾砂全固废充填采矿法，属于固体废物固化处置与充填采矿法的交叉技术领域。该方法利用镁渣危废替代水泥熟料，制备镁渣基充填胶凝材料；然后开展不同胶砂比和料浆浓度的胶结体强度和充填料浆的流变性试验；采用压汞仪法对胶结体进行孔结构分析；根据试验与测试结果，建立胶结体强度、料浆流变参数以及胶结体最可几孔径与胶砂比和料浆浓度的关系；最后建立和求解充填料浆的优化模型，获得充填料浆的优化参数。该方法实现了全固废绿色充填采矿，不仅提高充填采矿的经济与环保效益，而且还为镁渣危废的资源化、减量化和无害化处置以及高值化利用探索出一条途径。
