In transfer system, the main structure parameters which affect the coal flow velocity at outlet of the curve coal chute have been obtained according to the generatrix equation of cure coal chute. Dynamic models of the coal flow velocity inside curve coal chute were established, based on the discrete element method, Discrete Element Model (EDEM) software was utilized to study the influence of parts of the system parameters and the structure parameters of the curve coal chute on the horizontal and vertical coal flow velocity at the outlet of curve coal chute. Study results show that the variation of the height, center distance and the angle at the outlet of the curve coal chute influences directly on coal flow velocity of curved coal chute. By adjusting the above three parameters, the coal flow velocity at the outlet of curve coal chute can be controlled to the target value, therefore the phenomenon of belt abrasion and dust emission caused by the relative moment between the coal flow and the transfer belt is reduced.
