A method for the determination of gas-dynamic phenomena type according to which one determines the level of adsorption of methane from samples at room temperature and temperature that does not exceed 50 °C, one calculates activation energy of methane emission from coal E for samples from unshear zoneand zone affected by gas-dynamic destruction, with bringing into consideration a criterion of the gas-dynamic phenomena typeas ratio of differenceandto, one determines the type of gas-dynamic phenomena under the condition: ifaccidental emission,accidental release, ifrock bump occurs. |
