东北阜新煤田是中生代晚期典型的同沉积构造作用下形成的断陷型陆相聚煤盆地。成煤期间,在盆缘同沉积断裂构造及盆内同沉积短轴背斜隆起构造作用下形成的盆缘冲积扇与厚煤层的形成有着密切的成因联系。形成的厚煤层灰分及含硫较低,煤质好,其中有些富煤带的煤层巨厚,埋藏浅,利于开发,部分已进行露天开采,已为我国社会主义建设提供了大量优质煤炭。 The northeast Fuxin coalfield is a fault-type continental coal-formed basin formed under the typical syndepositional structure in the late Mesozoic. During coal formation, the basin margin alluvial fan formed by the basin margin synsedimentary fault structure and the syndepositional short axis anticline in the basin is closely related to the formation of thick coal seams. The formation of thick seam ash and sulfur content is low, good quality coal, of which some rich coal seam thick coal seam, shallow buried, conducive to development, some have been open-pit mining, has provided a large number of high-quality coal for our socialist construction.
