All-solid-waste filling material for green filling mining of mine and proportioning method of all-solid-waste filling material
The invention belongs to the technical field of mine filling materials, and discloses an all-solid-waste filling material for green filling mining of a mine and a proportioning method of the all-solid-waste filling material. The all-solid-waste filling material comprises the solid mass concentration and the proportion of shale slag, steel slag and granulated blast furnace slag, the solid mass concentration of the filling material is 67-69%, waste materials used for filling comprise the shale slag, the steel slag and the slag, the mixing amount of the shale slag accounts for 50-54% of the total solid, the mixing amount of the steel slag accounts for 40-44% of the total solid, the mixing amount of the slag accounts for 4.5-6.5% of the total solid, and the mixing amount of the granulated blast furnace slag accounts for 4.5-6.5% of the total solid. And no additive is added except tap water for mixing. The material prepared by the matching method has the characteristics that the strength meets the filling requirement, the fluidity is good, the cost is low, the environment-friendly and energy-saving effects are realized, and the early strength is realized. The utilization rate of the steel slag and shale slag solid waste is greatly increased, the problem that the solid waste occupies the land is solved, pollution to a stacking site is reduced, the full-solid-waste filling material leachate meets the groundwater three-class water standard, and the pollution problem existing in the filling environment is effectively solved.
本发明型属于矿山充填材料技术领域，公开了一种矿山绿色充填开采全固废充填材料及其配比方法。包括固体质量浓度，页岩渣、钢渣和粒化高炉矿渣比例，所述充填材料的固体质量浓度为67～69％，用于充填的废料为页岩渣、钢渣和矿渣，所述页岩渣掺量为总固体的50～54％，所述钢渣掺量为总固体的40～44％，所述矿渣掺量为总固体的4.5～6.5％，除自来水用于拌合以外无任何添加剂。本配合比方法制作出材料具有强度满足充填要求、流动性好、成本低、并且环保节能和早强型的特点。不仅较大程度的提高了钢渣和页岩渣固体废弃物的利用率，解决了固废占地的问题，降低对堆放场地的污染，而且全固废充填材料浸出液满足地下水三类水标准，有效解决了在充填环境中存在的污染问题。
