In the geological structure of the studied area are rocks of formations. С² and С³ coal-bearing strata of the middle Carboniferous, which come to the surface in the form of a narrow (0.5-2.5 km) strip along the axis of the Main Donetsk anticline, called in this part Gorlovskaya. To the north and south of this band, the rocks of the overlying coal-bearing formations that form the wings of the fold come to the surface. The rocks here have a steep (50-65°) dip, and their outcrops extend almost linearly in the west-northwest and east-southeast directions.The axial part of the anticline is complicated by shallow folded forms and a large number of discontinuities, different in age and character.
