Abstract:

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.

Key words: pipeline transportation, numerical simulation, theoretical calculation, resistance loss
