Physicaland chemical changes in the coal exposed to electric fields of weak intensity, the coal after a sudden outburst, and that selected from outburst-prone and non-hazardous zones have been analyzed using X-ray analysis, EPR, thermogravimetric analysis, DSC, laser diffraction analysis of particle sizes, IRspectrometry, NMR, Raman spectroscopy and cross-polarization.Coal organic matter (COM) was shown to be destructed not only by mechanical ...
