Abstract: Three-dimensional simulations of diesel particulate matter (DPM) distribution inside a single dead end entry with a push-pull system for the load-haul-dump (LHD)-truck loading and truck hauling operations were carried out using ANSYS FLUENT computational fluid dynamics (CFD) software. The loading operation was performed for a fixed period of time. Then dynamic mesh technique in FLUENT was used to study the impact of truck motion on DPM distribution. The resultant DPM distributions are presented for the cases when the vehicles were fitted with and without diesel particulate filters (DPF). The results from the simulation can be used to determine if the areas inside the single dead end entry exceed the current U.S. regulatory requirement for DPM concentration (160 µg/m3). This research can guide the selection of DPM reduction strategies and improve the working practices for the underground miners.
