prevention of Methane layering and local accumulations in dead-end headings

The article describes inevitable conditions at gaseousness of dead-end development headings because of ventilation loss in fan pipes. The article presents particular cases of determining the required volume of air leaks in dead-end development headings ventilating by booster fans with collapsable air ducts through ventilation columns in order to methane layering and local accumulations prevention in particular areas of dead-end development headings. The necessity of the fan pipes conection with elements and means for removing fresh air from the vent in its upper part to prevent methane accumulations is proved.

Key words: LAYERING AND LOCAL METHANE ACCUMULATIONS DEADEND HEADINGS, VENTILATION LOSS, FAN PIPE.
