STRUCTURAL AND DISCRETE ELEMENT ANALYSIS OF COAL MINE CONVEYOR SYSTEM
The aim of this study is to determine the relationships between the operation speed and occurred stresses on the designed coal mine conveyor system. Coal mine system was designed using solid state modelling in CAD (Computer Aided Design) software. The loads caused from the granular material (coal) were calculated with DEM (Discrete Element Method) analysis. The structural analysis was applied to the system with Finite Element Analysis (FEA) Method in the Ansys Workbench Static Structural environment through the results from DEM analysis. The operation speeds of the system for the analysis were defined as 1, 2 and 4m/s. The loads were obtained as compressive forces from the DEM according to the velocity of the conveyor belt and these loads were applied to the conveyor in structural analysis. The occurred stresses on the structure were calculated as about 72, 96 and 118MPa for 1, 2 and 4m/s velocities, respectively. These results showed that the operation speed had a significant effect on the loads acting on the system and structure.
