Structural features of coals in zones of outburst-hazardous geological disturbances
The results are given of investigation by methods of structural physical chemistry of the distinguishing features of the molecular structure and supermolecular organization of coals in zones of outburst-hazardous geological disturbances. The processes of the mechanicochemical degradation of coals in zones of outburst-hazardous disturbances took place more intensively than in nonhazardous zones and caused a substantial rise in the degree of looseness of the molecular and supermolecular structures and an increase in the concentration of paramagnetic centers in the coals. It is proposed to use structural indices to predict the potential outburst-hazardousness of coal beds in zones of geological disturbances. 1 ref.
