LEADING ENGINEERING SIMULATION CONFERENCE
Mine conveyance systems are essential for transporting equipment and personnel deep underground via vertical shafts which can be in excess of 1km deep. The shaft that the conveyance systems run in are required to perform a multitude of functions including housing the main conveyance system, supplying fresh air to the workers underground and as an umbilical cord providing water and electricity services from the surface.
Due to the costs involved in drilling large diameter shafts, there is a desire to maximise the conveyance cage physical dimensions and travel speed as well as ventilation flow velocities. However, this can result in unsteady lateral aerodynamic forces which can be uncomfortable for personnel.
The conveyance system has been modelled using dynamic fluid-body interaction (DFBI) in STAR-CCM+®. This has enabled different ventilation flowrates and cage configurations to be investigated and measures put in place to reduce these lateral accelerations.
