The dispersion of diesel contaminants into the mine atmosphere is a variant of general class of diffusion-dilution problems relevant to underground mining practice. The equipment operations in underground mining are characterized by different activities with different time durations, i.e. varying duty cycles. Therefore the volume and quality of diesel emissions and consequently, instantaneous concentrations are quite variable. Design of mine ventilation systems under these conditions becomes complex. In this paper, the development and use of mathematical models of mine production system, the engine exhaust air quality and engine exhaust transport in the design of ventilation system are discussed.
