The difference of forcing status between coal and gangue in the process of impact was a fundamental problem in separation of them. In order to finding out forcing status of coal and gangue, the impact process was emulated by finite element software. The variation curves of contact force, the time-course curves of stress and pressure at different locations on material and board hammer were gained. The simulation results showed that for the different material properties, stress and pressure variation of coal were less than gangue, and the impact point in board hammer has the worst forcing status.
