The results of the coal-bearing strata geological structure analysis in the Presalair strip of Kuzbass are presented. As a reference, the material on the geological structure of the Vakhrushevskiy coal mine was used, it is located in direct contact with geological structures of the Salair ridge. The division of Salair and Kuzbass runs along the Tyrgan lineament, which has been identified with the mass overthrust by authors. Ahead of the mass overthrust front, coal-bearing strata of the Upper Balakhonian subseries of the Lower Permian are crushed into a series of narrow anticlinal and synclinal folds. At the same time, nuclear parts of anticlinal structures are fragmented and complicated by disjunctive dislocations. The system of ruptures determines the structure of coalbearing area, forming a series of tectonic plates parallel to the direction of the Tyrgan lineament. The direction of the plates movement along these dislocations is close to vertical. Horizontal strike-slip dislocations typical for the western Altai-Sayan folded region are absent here. Extended tectonic plates with extensive, weakly dislocated beds of coal (extended both along the strike and downward) should be considered as the most promising for mining.
