Diesel Emissions The exposure of mine workers to diesel particulate matter (DPM) and gases is an issue of great concern to the underground mining environment. Diesel engines work by igniting a mixture of fuel (a hydrocarbon) and intake air in the combustion chamber. At high temperatures, fuel may decompose rather than burn, leaving a complex…
When air enters any mine or other subsurface structure, it has a volume composition of approximately 78 percent nitrogen, 21 percent oxygen and 1 percent other gases on a moisture free basis. However, as the air progresses through the network of underground openings, that composition changes. There are two primary reasons for mine ventilation.…
