Waste space and its influence on the operation modes of the main ventilation fans

Article preview

Worked out spaces with sufficiently large volume of cavities are not able to reverse air streams in the downcast shafts and adjacent drifts for a long time (up to 90 min) thus creating dangerous conditions for evacuation of miners. An emergency situation has been analyzed on the basis of a ventilation system model.
