Abstract
Poor performance in coal loading of thin coal shearer is the main reason affecting thin coal mining efficiency. In the paper, the development of thin coal shearer coal loading performance was summarized and the lack of the related researches was pointed out. According to the working features of dip angle of thin coal shearer at the different working faces, a simplified model of drum coal loading was set up. The influence rules of dip angle on drum pushing and drum ejection coal loading performance were studied by discrete element method (DEM) simulations and the prime factors of drum coal loading rate significantly influenced by dip angle were identified. In addition, according to the poor drum coal loading rate, the improvement suggestions were proposed, and verified through DEM simulation.
