METHOD FOR MINE VENTILATION

摘要

The invention relates to mining, in particular to ventilation of mine workings. Method for ventilation of mine prescribes supply of outer air to air-supply stem, its heating in mouth of stem to temperature not smaller than +2C. After that air is supplied to channels formed in worked-out space between air-supply and air-discharge development workings. Air that goes out of channels is directed to swirl tube. Flow of hot air from it is directed through ventilation stem to surface. The invention promotes decrease of consumption of energy carriers for mine ventilation.
