中文摘要: 为研究矿山尾矿库分级尾砂用于矿山充填,主要从尾矿库分级尾砂的物理化学性质、粒级组成进行了分析研究,通过分级尾砂的沉降性试验、坍落度试验和强度试验,试验结果表明将尾矿分级尾砂充填料浆的灰砂比1:4~1:8、料浆浓度68%~72%时料浆具有较好的流动特性、可泵性和充填单轴抗压强度,论证了尾矿库分级尾砂可用于矿山充填,提升了矿山充填生产能力和固废物处置能力,有效解决了矿山采充平衡问题,可为同类矿山提供参考借鉴。
Abstract:In order to study the application of graded tailing in mine filling, the physical and chemical properties and particle composition of graded tailing are analyzed. The results show that the slurry has better flow characteristics when the ratio of ash to sand is 1:4 ~ 1:8 and the concentration of slurry is 68% ~ 72% , pumpability and filling uniaxial compressive strength. It is demonstrated that the tailings can be used for mine filling, which improves the production capacity of mine filling and solid waste disposal capacity, effectively solves the problem of mining filling balance, and provides reference for similar mines.
