Mathematical models for the study of geo- and gas dynamic processes during anti-outburst prevention measures, methods for determination the gas pressure and filtration coefficients at interval measurements of gas emission rate during the current predication of the outburst hazard were developed. Impulse character of the methane desorption from the coal seam in disturbance of its equilibrium state has been established for the first time.
