Abstract: The analysis of the distribution trait of the coal seam, sedimentary facies and paleogeography, environment types of coal accumulating and the temporal and spatial distribution in the Early Permian of Ordos Basin shows that the main coal accumulating sedimentary systems are beachbarrier, tidal delta and fluvial or delta plain, and the continental mire marshes and the marine peat flat are the main coalbearing environment. The three main coalbearing systems are the beachbarrier coal accumulating system, the tidal delta coalbearing system and the fluvial or delta plain coalbearing system, which formed the main economic coalbed. The controlling factor of the formation and protection to the coalbed is the accommodation space variation rate which is relevant to the peat sediment.
