RÉSUMÉ

As the result of performed experiments the method based on determining of intensities of wide and narrow lines in the spectrum of the coal samples, which characterize the number and the energy of hydrogen nuclei in coal, is developed using the nuclear magnetic resonance method. An integral factor determining the gas dynamic state of the coal massif in time and in space is obtained. Growing ratio of narrow line to wide line in the spectra of nuclear magnetic resonance (NMR) 1H is witnessing for getting closer to the coal and gas outburst source, which is in itself a gas dynamic event (GDE). Implementation of this method at coal-mining works demonstrated high reliability of using the methods of 1H NMR spectroscopy for forecasting the sources of outbursts.
