As a result of experimental studies it was stated as follows: there are disagreements between stress and strain states for test coals; effect of stress states on physical and mechanical behaviors of coals; variations of physical and mechanical behaviors of coals with increase of occurrence depth, the elaborated method of determining of limiting state zone. It has been received the further development of spatial geomechanical model for the study of stress-strain state of underworking layered rock massif taking into account the presence of tectonic disturbances on the working face. On the basis of the obtained results it is developed "Methods of the forecast of zones of accumulations of methane in underworking coalbed satellites under tectonic disturbance", which is transferred to Private aktsionerne tovaristvo "Pokrovskoe mine" and Way of predicting of zones of accumulations of methane "in the form of a patent of Ukraine".
