高浓度全尾砂自流输送在金属矿山的应用日趋广泛。通过对某铁矿高浓度全尾砂胶结充填管道输送进行数值模拟研究，确定高浓度全尾砂料浆相关物理参数，构建适合高浓度全尾砂胶结充填料浆管道输送的数值模型。利用ANSYS/FLOTRAN模拟高浓度全尾砂料浆在充填管道内流动的动态特征，并将模拟结果与理论计算进行对比分析，同时进行料浆输送过程的数值解算，分析结果显示：（1）料浆浓度在68%~78%范围内以1.5，2.0，2.5 m/s进口流速完全能实现自流输送；（2）模拟结果与理论计算对比分析得出二者阻力损失相对比较一致；（3）随着料浆进口流速的增大，料浆浓度对弯管处的冲击影响越不明显。研究表明该数值模型建立合理，研究结果对高浓度全尾砂胶结充填管道自流输送试验和实践提供了一定的指导与借鉴。

The Gravity-flowed Convey of high-density whole tailing is already widely applied as time goes on and distributed around the globe in metal mine.A detailed numerical simulation study was conducted of a pipeline transportation of high-density whole tailing of iron ore，and based on high-density whole tailing slurry，main physical parameters are defined and the construction of the numerical model of the pipeline transportation of high-density whole tailing cemented filling slurry was also completed at the same time.Depend on the application of ANSYS/FLOTRAN，we will simulate the dynamic feature of high-density whole tailing slurry when it works in the pipeline，and also conducted a comparative analysis between the simulated result and the theoretical value.At the same time，the numerical calculation of transportation of slurry was also conducted and studies the result of the calculation.The slurry whose concentration is between 68% and 78% will achieve Gravity-flowed Convey by the intake velocity of 1.5 m/s，2.0 m/s and 2.5 m/s.When it comes to the simulated result and the theoretical calculation，we find resistance loss of both are almost unanimous.With the initial velocity of slurry increasing，the impact force coming from the concentration of slurry is becoming lighter and lighter at the same time.At last，we can conclude that the numerical model is reasonable and practicable，and this review would provide a theoretical guide for the application of Gravity-flowed Convey of high-density whole tailing cemented filling slurry.
