 Abstract. The questions of analysis of efficiency of airgasdynamic processes control on the working areas of coal mines are considered. It is shown that maintenance of the air-taking workings abandoned behind front of cleansing works promotes the prime price of the obtained coal, but allows at charts 2-B and 1-K to insulate near-face space from produced one, to provide the high loading on the face and reduce the terms of working off a panel. Growth of aerodynamic resistance and depression of the working area ventilated on a chart 2-B is related exceptionally to the increase of resistance of the air-taking woking; intercommunication between the level of gas content of area and growth of aerodynamic resistance of the air-taking working in time, causing a transition necessity to the combined chart of ventilation 1-K, is set, at which taking of gas-air masses is conducted simultaneously on two air-taking workings in various directions due to generalmine depression. Such transition allows to reduce aerodynamic resistance of area more than in 10 times at that carrying capacity of the delineation workings.

Keywords: airgasdynamic processes, working area, asr-taking working, charts of ventilation.
