Fundamental understanding of diesel-operated man riding vehicle DPM dispersion – A case study

In this paper, an attempt has been made to model DPM flow patterns in the vicinity of man riding vehicle(s) operating a coal mine environment. The are modelled using techniques computational fluid dynamics (CFD) and validated field experimental measurements. models show that if vehicle is stationary, particles dispersed towards center gallery. Beyond 20 m downstream vehicle, occupy entire cross-section roadway. If movement considered, miners may be exposed high concentration due engines running at full capacity resultant air induced by vehicle.
