Under the condition of m/s for filling industrial pump accessories, industrial filling pump accessories, and tailings paste filling pump accessories in Jinan, Shandong, the pressure loss of the paste filling slurry pipeline using a 66.15% mass concentration full tailings filling industrial pump and industrial filling pump was reduced by 36.46%, 39.37%, and 40.17%, respectively, compared to a 64.13% mass concentration graded fine tailings filling industrial pump and industrial filling pump; The strength of paste filling using graded fine tailings filling industrial pumps and industrial filling pumps is lower than that of paste filling using full tailings filling industrial pumps and industrial filling pumps. Compared with paste filling using full tailings filling industrial pumps and industrial filling pumps, the 3D strength of paste filling using graded fine tailings filling industrial pumps and industrial filling pumps corresponding to the slurry state and ash sand ratio is reduced by 50% to 80%, The difficulty in handling fine particle tailings during paste filling with industrial pumps and industrial filling pumps for 28 day strength reduction gold mine filling, low concentration of paste filling with industrial pumps and industrial filling pumps, and low strength of paste filling with industrial pumps and industrial filling pumps are technical challenges. Research has been conducted on the physical and chemical properties of paste filling materials using industrial pumps and industrial filling pumps, the settling characteristics of fine particle tailings, the strength ratio test of fine particle tailings, and the flow performance of paste filling slurry using industrial pumps and industrial filling pumps. A technical transformation plan for the paste filling system of Xiadian Gold Mine filling industrial pumps and industrial filling pumps has been proposed, and on-site technical transformation has been completed The on-site application results show that when the ash to sand ratio is 1:7-1:8 and the paste filling capacity of the filling industrial pump and industrial filling pump is ≥ 60%, the strength of the paste filling body of the filling industrial pump and industrial filling pump after 3 days is ≥ 1 MPa, which meets the mining requirements of Xiadian Gold Mine. It not only solves the problem of fine particle tailings discharge and reduces the capacity pressure of the tailings pond, but also improves the utilization rate of mine tailings The pipeline transportation characteristics of paste filling slurry in mining tailings filling industrial pumps and industrial filling pumps were studied. Based on the Bingham fluid model in fluid mechanics, a paste filling system was developed by combining mining filling industrial pumps and industrial filling pumps. Experimental research was conducted on the self flow transportation of paste filling slurry using L-tube filling industrial pumps and industrial filling pumps By using the ratio of adhesive to sand, they are山东济南充填工业泵配件、工业充填泵配件、尾砂膏体充填泵配件m/s情况下,质量浓度66.15%的全尾砂充填工业泵和工业充填泵进行膏体充填料浆管道压力损失分别比质量浓度64.13%的分级细尾砂充填工业泵和工业充填泵进行膏体充填料浆管道压力损失降低了36.46%,39.37%,40.17%;分级细尾砂充填工业泵和工业充填泵进行膏体充填体强度低于全尾砂充填工业泵和工业充填泵进行膏体充填体强度,相比于全尾砂充填工业泵和工业充填泵进行膏体充填体,对应料浆状态及灰砂比的分级细尾砂充填工业泵和工业充填泵进行膏体充填体3d强度降低了50%~80%,28d强度降金矿充填工业泵和工业充填泵进行膏体充填存在的细颗粒尾砂处理困难,充填工业泵和工业充填泵进行膏体充填浓度低,充填工业泵和工业充填泵进行膏体充填体强度低等技术难题,开展了充填工业泵和工业充填泵进行膏体充填材料物理化学性质研究,细颗粒尾砂沉降特性研究,细颗粒尾砂强度配比试验研究,细颗粒尾砂充填工业泵和工业充填泵进行膏体充填料浆流动性能研究等,提出了夏甸金矿充填工业泵和工业充填泵进行膏体充填系统技术改造方案,并完成了现场技术改造.现场应用结果表明:细颗粒尾砂(-74μm)在灰砂比1:7~1:8,充填工业泵和工业充填泵进行膏体充填能力≥60%时,充填工业泵和工业充填泵进行膏体充填体3 d强度≥1 MPa,满足夏甸金矿开采要求,不仅解决了细颗粒尾砂排放问题,减轻尾矿库库容压力,而且还提高了矿山尾砂利用率. 矿山全尾砂充填工业泵和工业充填泵进行膏体充填料浆的管道输送特性,基于流体力学中Bingham流体模型,结合矿山充填工业泵和工业充填泵进行膏体充填系统,开展了L管充填工业泵和工业充填泵进行膏体充填料浆自流输送试验研究.通过胶砂比分别为
