An analysis of the first gas dynamic phenomena realization depth in different coal seams is conducted, and the estimation methodic of the outburst hazard minimal depth, for which it is necessary to carry out the prognosis of the outburst hazard while mining, is considered. It is shown, that for estimating the outburst hazard it is necessary to set criterion correlations, that characterize the changes of diffusive and sorptive resources of methane in coal. Provided the correct choice of the criteria on the basis of the informative-analytical model, offered by IGTM NAN of Ukraine, the problem of the outburst hazard estimation of the coal seams can be decided.
