The subject deals with the main and auxiliary mine ventilation, including the
ventilation of dead end mine workings and the optimization of mine
ventilation. The basic principles of aerodynamics are explained as a basis for
understanding the process of underground air flow and ability to perform the
relevant calculations and solving the mine ventilation networks. Natural and
thermal air flows, fluctuations of quarry air characteristics, basics of
meteorology and force ventilation of opencast mine ventilation are discussed
as well.
