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...

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 ...
