size is 3.75mm and 14.13mm, respectively. The coal slurry concentration of clean coal 1 and 2 is 10.2% and 11.5%, respectively. The average velocity of clean sample 2 slurry was set at 4.5 ms-1 and 5.5 ms-1 in the initial stage. The particle size grading of coal slurry with different flow distance, including 1500m and 4500m, was measured (Fig.3).
