Abstract

In view of the current situation of mining more and more medium thick and steep coal seams in recent years, taking a certain type of shearer drum as the research object, the working state of the drum is analyzed with the help of EDEM software. In this paper, SolidWorks is used to establish the three-dimensional model of the shearer drum. After importing EDEM software, the gangue rock model of the gangue layer with different angles is established according to the position of the 3D model of the drum. The angles of the gangue bedding are 15°, 0° and- 15° respectively. The cutting speed, traction speed and coal seam thickness of the shearer with the same value are adopted, The influence of bedding angle of gangue on shearer drum cutting is studied. The results show that the greater the angle between the gangue layer and the horizontal plane, the greater the impact load on the drum. The working condition of the shearer for cutting medium thick coal seams with gangue is complex and the impact load changes greatly.
