  • 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 beachbarrier, tidal delta and fluvial or delta plain, and the continental mire marshes and the marine peat flat are the main coalbearing environment. The three main coalbearing systems are the beachbarrier coal accumulating system, the tidal delta coalbearing system and the fluvial or delta plain coalbearing system, which formed the main economic coalbed. The controlling factor of the formation and protection to the coalbed is the accommodation space variation rate which is relevant to the peat sediment.

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 beachbarrier, tidal delta and fluvial or delta plain, and the continental mire marshes and the marine peat flat are the main coalbearing environment. The three main coalbearing systems are the beachbarrier coal accumulating system, the tidal delta coalbearing system and the fluvial or delta plain coalbearing system, which formed the main economic coalbed. The controlling factor of the formation and protection to the coalbed is the accommodation space variation rate which is relevant to the peat sediment.
