The possibility of using a multifractal approach to study the tectonic disturbance of coals has been investigated. The relationship between the coal disturbance and the asymmetry of fractal spectra of coal images obtained by means of scanning electro

The phenomenon of increased gas release in coal and gas outbursts has been known for a long time, while no common opinions on the causes of this phenomenon exists yet. An abrupt change in the stress state of coal with high gas content during face adv

The multifractal spectra of electronic images of fossil coal surfaces obtained from outburst-hazardous zones, outburst-nonhazardous (quiet) zones and outburst zones are studied. It is shown that the structural organization of coal surface elements ca

It is investigated the possibility of using so–called "complexity–entropy" diagrams for the quantitative description of the degree of coal disturbance using coal images obtained by means of scanning electron microscope (SEM). These diagrams plot

The authors have developed a geodynamic model and formulated conditions of avalanche self-sustained failure of coal in face zone based on analysis of the accomplished physical modeling and in situ observation of failure of coal in limit stress state.
