Abstract: The article presents the results of research work on the assessment of mining and geological conditions, determination of zones of influence of overworking and underworking, determination of calculated deformations of rocks for the development of recommendations for trouble-free mining of passes in the conditions of the mine named after A.D. Ruban. A combined method for controlling geomechanical processes is considered, including the processes of preliminary development of a powerful shallow reservoir and subsequent development of this reservoir by an underlying reservoir. The work was carried out according to a specially developed methodology, which provides theoretical methods for studying the parameters of overworking and underworking of the coal seam and direct studies of geomechanical processes in mine conditions. According to the existing normative and technical documentation, the deformation processes are calculated, the calculated deformations of compression and unloading of rocks are determined, the parameters of the reference pressure zones are determined, etc.

Key words: Formation of layers advanced operating time part-time of layers reference pressure zones rational order
