Evaluation of a Proposed Dust Ventilation/Collection System in an Underground Mine Crushing Plant

摘要

Computational Fluid Dynamics (CFD) modelling of a dust collection system in an underground mine crushing plant was carried out. Dust was collected/absorbed through the holes along the top edge of Run of Mine (ROM) bin. The dust collection performance of the system is summarised. The detail results are presented in the form of velocity vectors and dust concentration iso-surface contours. Time dependent dust concentration isosurfaces are also presented. Dust was found to be well contained within the crusher bin and stands out as a viable option. However, the velocity magnitudes were found to be very high in and around the whole exits, which has the potential to lead to undesirable pressure drop and generation of noise.
