为了探究尾矿砂结构特征对其渗透性的影响,以尾矿砂圆柱模型为研究对象,采用FLUENT对不同实验条件下的尾矿砂圆柱渗透系数进行数值模拟,验证了数值模拟方法在求解渗透系数时的有效性。通过研究不同结构特征因素对尾矿砂圆柱渗透系数的影响,得出了渗透系数和颗粒直径、孔隙率之间的规律。在孔隙率固定不变的情况下,渗透系数和颗粒直径的平方近似呈正比关系;在颗粒直径不变的情况下,渗透系数和孔隙率的三次方成正比关系。极差分析结果显示,颗粒直径是影响渗透系数较大的因素,次因为孔隙率,且两者的影响都表现出正相关性。

In order to investigate the influence of tailings structural features to its permeability, and with the tailings cy- lindrical model as the research subject, the FLUENT software was used to simulate the permeability coefficient of tailings cylin- der to validate the reliability for obtaining permeability coefficient under the simulating experiment conditions. Through investi- gating the effect of different structure factor on permeability coefficient of tailings cylinder, the regularity among the permeabili- ty coefficient, the particle diameter and porosity was obtained. The permeability coef...
