FIELD: mining.
SUBSTANCE: proposed method comprises subjecting initial methane-air mix sucked by fan from underground working to wet dust separating, feeding it into absorber for methane-air mix to get in contact with methane-absorbing sorbent. Air cleaned of dust and methane is returned into mine or ejected into atmosphere. Sorbent saturated with methane is heated to 60-80°C to release methane to be cleaned of sorbent drops and forwarded for future use. Recovered sorbent is fed again into absorber. Note here that heat of recovered sorbent heated in desorber is recovered and transferred in reflux heat exchanger to sorbent saturated with methane fed into desorber. Invention covers device to implement above described method.
EFFECT: higher safety of mine operation, reduced emission of methane.
