FIELD: prognostication of gas and outburst phenomena. SUBSTANCE: method is based on experimentally found out relation between gas liberation from sample and difference of coal bas-bearing capacity at the moment of coal sampling and residual gas-bearing capacity corresponding to atmospheric pressure. Gas liberation from sample is measured in two stages: first, after taking sample from coal mass, and then, after obtaining of sorption equilibrium in vessel with sample. Method offers formula for determination of gas-bearing capacity. EFFECT: higher efficiency.
