The article is devoted to the analysis of the results of the mine instrumental measurements of the local degassing system of the m3 seam on the horizon of 1100 m of the mine named. V.M. Bazhanov to establish the basic rational parameters with the subsequent application of the biotechnological method of reducing the concentration of methane. As a result of mine instrumental measurements (vacuum-gas surveys at the borehole heads), the parameters of the degassing process (methane flow rate at the borehole heads and the average vacuum on them), technological parameters (angle of turn and tilt of wells, their length), well flow rate efficiency from the distance to the bottom of the longwall and the displacement of the undermined rocks. Establishing the basic parameters of degassing will allow you to quickly manage the flow rate of wells and underpressure at their mouths, taking into account the specific mining and geological and mining conditions. The use of biofilters allows controlling the concentration of methane in the atmosphere of mine roadway by methanotrophic bacteria.
