FIELD: mining.
SUBSTANCE: invention is related to mining, namely to method for purification of outgoing air jet from methane and its utilisation. Method includes formation of layer accumulation of methane. Prior to exhaust of mine air into atmosphere, it is sent to inclined mine tunnel, at the same time its speed is reduced 2-4 times, by means of closure of upper part in inclined mine tunnel by one third of its height. Methane-air mixture is extracted with the help of pump from layer accumulation and sent for combustion. Lower layers of mine air, which are free from methane, are sent to atmosphere from inclined mine tunnel. Incline of mine tunnel is selected within the limits of 8-12°, and outlet to atmosphere is done through rotary nozzle, which is turned by flank in wind direction. Length of mine tunnel is calculated in compliance with mathematical dependence with account of horizontal speed of air motion, speed of methane floating, height and inclination of mine tunnel.
EFFECT: provision of possibility to improve and simplify process of mine gas removal from mine.
