Low-frequency relaxation processes in disordered structures

The dielectric properties of dispersed coals, connected with the interaction of electrically active surface of the coal solid phase and water polar molecules were studied. It is established that the presence and quantity of water in the interlayer space of natural coal does not affect the structure of the crystal lattice of coal. The complexity of the structure of disperse systems, as well as the availability of local inhomogeneities determines the cause of the lack of current understanding of the mechanisms of the charge carrier’s transfer and the structure of the energy spectrum of such systems. The results of the experimental research of electrophysical characteristics of the moist mechanically activated fine-dispersed natural coals of Cheremkhovo basin are presented.
