Pipeline transportation is a crucial component of mine filling systems, and the rheological parameters of the filling slurry are essential for pipeline transport design. Taking the unclassified tailings filling slurry of Daye Iron Mine as the research object, the rheological parameters and pipeline transportation characteristics were studied by rheological test and Fluent numerical simulation. The results indicate that when the slurry mass concentration is between 60% and 70%, the fitted relationship curve between shear stress and shear rate conforms to the change rule of Herschel-Bulkley (H-B) model. With the increase of slurry mass concentration, the yield stress and viscosity coefficient increase exponentially, and the viscosity coefficient increases significantly when the slurry mass concentration reaches 70%. When the mass concentration is 60%−65%, the slurry flow is unstable and the pressure distribution in the pipeline is uneven. When the mass concentration is between 68% and 70%, the slurry flow state is relatively stable, and the pressure is symmetrically distributed along the pipe diameter. The resistance loss of the pipeline is positively correlated with the slurry mass concentration and the slurry flow rate. When the slurry mass concentration reaches 68%, the resistance loss begins to increase significantly. It is suggested that the mass concentration of filling slurry in Daye Iron Mine should be controlled between 65% and 68%. Considering that the maximum flow velocity of slurry appears at the bottom of vertical elbow (inflection point D), where wear-resistant materials should be used. The research results can provide a theoretical basis for the design of pipeline transportation parameters of mine filling system.

管道输送是矿山充填系统的关键组成部分,充填料浆流变参数是管道输送设计的依据。以大冶铁矿全尾砂充填料浆为研究对象,通过流变试验及Fluent数值模拟对其流变参数及管道输送特性进行了研究。结果表明:料浆质量浓度在60%~70%时,剪切应力与剪切速率的拟合关系曲线符合H-B模型变化规律;随着料浆质量浓度的增大,其屈服应力和黏度系数均呈指数上升规律,黏度系数在料浆质量浓度达到70%时显著增大;当质量浓度为60%~65%时,料浆流动不稳定,管内压力分布不均匀;当质量浓度为68%~70%之间时,料浆流动状态相对稳定,压力沿管径呈对称分布;管道阻力损失与料浆质量浓度和料浆流量成正相关,当料浆质量浓度达到68%时,阻力损失开始大幅增加;建议将大冶铁矿充填料浆的质量浓度控制在65%~68%之间,考虑到料浆的最大流速均出现在垂直弯管底部(拐点D处),此处应采用耐磨材料。研究结果可为矿山充填系统管道输送参数设计提供理论依据。
