Environment-friendly mine solid waste resource utilization method
The invention discloses an environment-friendly mine solid waste resource utilization method which comprises the following steps: 1) crushing and screening waste rocks, and crushing and screening tailings; (2) mixing the selected waste rocks and tailings with cement and fly ash; and (3) adding water into the mixture, and mixing to obtain the filling material, wherein the mass ratio of the water to the mixture is (1.5-3): 1. The filling material is prepared from the solid wastes, so that the overall strength of the filling material is enhanced, and the cost is reduced.
本发明公开一种环保型矿山固体废弃物资源化利用方法，包括以下步骤：1)将废石破碎并筛分，尾矿破碎并筛分；2)将以上选取的废石、尾矿与水泥、粉煤灰混合3)在以上的混合物中加水混合，得到充填材料，水和混合物的质量比为(1.5‑3)：1。本发明利用固体废弃物制作充填材料，充填料材料的整体强度增强，成本降低。
