Energy-saving mine ventilation
Journal of Mining Science, 2013The authors show three methods of energy saving in mine ventilation: recirculating airing, minimization of main mine fan pressure by privative adjustment, and two-parameter optimization of fan performance (by rotary velocity and angle of blades). Energy saving using any of the methods is illustrated in the article.

Mine exhaust ventilation fans provide essential fresh air. The extracted air from the mine is often moist and laden with dust, so that conventional silencers would very quickly clog as the wet dust forms on silencer baffles and blocks the perforations in the baffle skins.

Data mining applications in evaluating mine ventilation system
Safety Science, 2012Abstract A mine’s ventilation system is an important component of an underground mining system. It provides a sufficient quantity of air to maintain suitable working environment. Therefore, the status of mine ventilation should be tracked and monitored as a timely matter.

Mining ventilation networks are made up of the galleries and ducts through which the air is distributed inside the exploitations. The ultimate aim in these calculations is the dimensioning of the main fan which will supply fresh air to the mine.

Mine ventilation thermodynamics
1993Many of the world’s practising mine ventilation engineers—perhaps, even, the majority—perform their duties very successfully on the basis of relationships that assume incompressible flow. Some of those engineers may question the need to concern themselves with the more detailed concepts and analyses of thermodynamics. There are, at least, two responses
