Method for applying modified mine waste soil material to scour prevention of refuse dump slope
The invention relates to a method for applying a modified mine waste soil material to scour prevention of arefuse dump slope. According to the invention, part of solid waste produced in the mining process is sieved, obtained coarse-grained soil materials are poured on the final drainage slope surface, and a drainage anti-sliding cushion layer is formed; water is added into fly ash, ordinary Portland cement and industrial Na2SO4, uniformly stirred, sieved fine-grained soil is added, stirred to form uniform mixed slurry, a high-efficiency polycarboxylate superplasticizer is added, the artificial organic fibers are added, and stirring is carried out to obtain the modified soil. The modified material is sprayed to the drainage anti-sliding cushion layer of the final drainage slope surface through a high-speed pulp shooting machine. According to the method, a three-dimensional anti-scouring structure is formed on the finally-discharged slope surface of the refuse dump, meanwhile, the method has the advantages that the manufacturing cost is low, raw materials are easy to obtain, industrial waste is comprehensively utilized, and environmental friendliness is achieved, and the method haspractical value for scouring prevention and environmental protection of the slope surface of the refuse dump.
本发明涉及了一种改性的矿山废弃土料用于排土场坡面防冲刷的方法。将采矿过程中产出的部分固体废弃物过筛，得到的粗粒土料倾倒于终排坡面上，形成排水抗滑垫层；将粉煤灰、普通硅酸盐水泥和工业用NaSO，加水搅拌均匀，再加入过筛后级配良好的细粒土料，待搅拌成均匀混合浆体后，加入高效聚羧酸减水剂，再加入人造有机纤维搅拌，得到改性土料。利用高速喷浆机将改性材料喷射到终排坡面的排水抗滑垫层上。本发明在排土场的终排坡面上形成一个立体的防冲刷结构，同时具有造价低、原料易取、综合利用工业废物、对环境友好等优点，此方法对排土场坡面的防冲刷和环境保护具有实际价值。
