Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove noxious gases (typically NOx, SO2, methane, CO2 and CO). The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. The largest component of the operating cost for mine ventilation is electricity to power the ventilation fans, which may account for one third of a typical underground mine's entire electrical power cost.

Famous quotes containing the word underground:
“It is in our interests to let the police and their employers go on believing that the Underground is a conspiracy, because it increases their paranoia and their inability to deal with what is really happening. As long as they look for ringleaders and documents they will miss their mark, which is that proportion of every personality which belongs in the Underground.”
—Germaine Greer (b. 1939)
