为了研究粗骨料高浓度充填料浆管道自流输送问题，根据金川矿区的实际充填管路利用 Gambit 建立三维管道模型，依据料浆自身的特点以及结构流理论，在 Fluent(3D)求解器中进行数值模拟。通过对不同浓度及不同流量情况下管道阻力损失的分析以及对弯管处压力的分析，获得在满足强度和高浓度的前提下的最佳料浆输送浓度为78%~79%，最佳流速为90 m3/h。同时，通过坍落度试验以及工业试验对数值模拟的结果进行验证。结果表明，粗骨料高浓度料浆管道输送模拟是可行的，研究结果为矿山应用粗骨料高浓度充填提供了理论依据。

In order to study the pipeline gravity transport of high-density filling slurry with coarse aggregates, the Gambit was used to establish 3D pipeline models according to the actual filling line in Jinchuan and numerical simulations were performed in the solver of Fluent (3D) based on the slurry characteristics and the structure flow theory. Through analyzing the resistance loss of the pipeline and force condition of the elbow under different concentrations and volume fluxs, the best transportation concentration of slurry is 78%?79%, and the optimal flux is 90 m3/h on the premise of meeting the requirement of strength and high-density. At the same time, the results of numerical simulation through the slump test and industrial experiment were verified, the pipeline simulation of high-density slurry with coarse aggregates is feasible, the result provides a theoretical basis for applying high density filling with coarse aggregates in mine.
