河西走廊东部石炭系发育、展布受晚古生代前陆盆地控制。虽然以武威为界的东、西两部存在一定差异，但均具有沉降中心和聚煤中心由南向北迁移，海侵方向由ＳＷ→ＳＷＷ→ＮＷＷ变化的特征。聚煤中心可能主要位于西部中央隆起南缘及东部靖远磁窑一带，北祁连逆冲推覆体下及山前可能也有较好的找煤前景。
The Carboniferous in east Hexi Corridor is developed and controlled by Late Paleozoic foreland basin. Although there is a certain difference between East and West in Wuwei, both of them have the characteristics of subsidence centers and coal accumulation centers migrating from south to north, and the direction of transgression changes from SW → SWW → NWW. The coal accumulation center may be mainly located in the southern margin of the central central uplift and the Jingyuan magnetic kiln in the east. Under the thrusting and piedmont of the North Qilian there may also be a good prospect of finding coal.
