A pipeline model is built and the evaluation is made through the simulation software Fluent. It is revealed that the super fine tailings are easy to suspend and the large-tube pipeline transportation is beneficial to reducing the frictional resistance loss. With the working flow rate of 2.95 m·s^-1, the pipeline's inner diameter of 155 mm, the vertical component of the fluctuating velocity reaches 0.24 m·s^-1, which is far greater than the hindered settling rate of 0.034 m·s^-1, and the maximum stowing gradient is up to 10.6., authors=TIAN Minghua^1,2, WANG Xinmin¹, ZHANG Guoqing¹, ZHANG Qinli¹, LI Shuai¹, authorsList=TIAN Minghua, WANG Xinmin, ZHANG Guoqing, ZHANG Qinli, LI Shuai, authorCompany=1.
