Most of the coalfield is covered by loess. The strata are sporadically exposed. The strata turn to the north east, with a tendency of northwest and a dip angle of about 5 °. The main structures of the mining area are Zhaojiayuan anticline, Shijiahe anticline, Jingjiapu anticline, Chenzhaozhen fault, F_2, F_2, F_3, , Bailongtan fault (F_5), Dukanggou fault (F_6) and so on. In general, the fold is dominated by short axis anticlines, and faults except Jujube Miao and Dukang Gully are NW-trending reverse faults, while others are NE-normal faults. Small and medium-sized mining area, according to the production of mines and supplements
