The coal basin (coal-bearing basin) is a large area (thousands of km²) of continuous or intermittent development of coal-bearing sediments (coal-bearing formation) with layers (deposits) of fossil coal (lignite, brown, stone).
The common geological and historical process of sediment accumulation in a single large tectonic structure (trough, grabene, syneclise) is characteristic of different parts of the coal basin. In some cases, according to historically established ideas, the dismembered large coal-bearing areas are not combined in the basin, despite the common genesis, and are considered as separate deposits.
The boundaries of the coal basin are genetic, tectonic, erosive, and with deep coal occurrence are conditional, determined by the technical capabilities of exploration, mining or quarrying.
