A transfer point is an element of a belt conveyor prone to increased energy losses and to the risk of failure. It is also a location in which the receiving belt is particularly susceptible to damage. Except failure-free operation, a transfer point should offer minimal belt resistances to motion by ensuring that the transported material is placed centrally on the receiving belt, both spillage of the material and blockages are prevented, the process of particle defragmentation is limited, and also that noise and dust emissions to the environment are reduced. Ensuring that the above requirements are met requires inter alia the use of advanced simulation tests. The article analyzes the flow of ore particles stream through a longitudinal transfer point used in an underground copper ore mine. Discrete Element Method was used to identify the phenomena which occur while transferring ore onto the receiving conveyor. The research allowed key variables affecting the transfer point performance to be identified. It also resulted in a proposal of actions which can improve the performance of the transfer point and which are focused on saving energy and on minimizing the damage and wear of the receiving belt.
