The Study of Water Content on the Coal Loading Performance of Thin Coal Seam Shearer Drum by Discrete Element Method (DEM)

Engineering Reports, Volume 7, Issue 1, January 2025.
Loading methods, helical angles, and rotation speed of drum have significant effects on the loading rate of drum. In this study, Discrete Element Method (DEM) is used to study what effects of these several factors have on the loading rate under different water contents.
