Diesel Emissions

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…

Mine Ventilation

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.…
