Diesel-operated man-riding vehicle and Load Haul Dumpers (LHD) are commonly used in underground mines.
These vehicles are used to minimize the miners’ travel time between working sections and loading operations. An
inevitable side effect of using these diesel-operated vehicles is the generation and dispersion of diesel particulate
matter (DPM). This is an urgent concern, because DPM is known to be a carcinogenic agent that can have a
serious adverse effect on the miners’ health after prolonged exposure. This paper presents DPM flow patterns of
LHD and man-riding vehicles using Computational Fluid Dynamics (CFD) modelling studies.
