渭北石炭二迭纪煤田,位于祁吕贺兰山字型构造的前弧东翼内侧与新华夏系第三巨型沉降带中段——陕甘宁盆地南缘的复合部位,南邻秦岭纬向构造带。澄合、蒲白矿区则位于渭北煤田的中段。区内含煤地层为上石炭统太原群及下二迭统山西组,可采煤层主要含于太原群。太原群为一套海陆交互相含煤沉积,直接覆盖于下、中奥陶统灰岩之上。其岩性主要为灰、深灰、灰黑色泥岩、砂质泥岩及粉砂岩,其次为浅灰、灰白色石英砂岩,夹黑灰、深灰
The Weibei Carboniferous-Permian Coalfield is located inside the east wing of the eastern arc of the Qilu Helan Mountain figuration and in the middle part of the third giant sedimentary belt of the Neo-Cathay, the southern margin of the Shan-Gan-Ning Basin. The south Qinling weft belt . Cheng, Pu Bai mining area is located in the middle of Weibei coalfield. The coal-bearing strata in the area are the Upper Carboniferous Taiyuan Group and the Lower Second Permian Shanxi Formation. The recoverable seams are mainly contained in Taiyuan Group. Taiyuan group as a sea-land interaction phase coal deposit, covering the lower, middle Ordovician limestone. Its lithology is mainly gray, dark gray, gray-black mudstone, sandy mudstone and siltstone, followed by light gray, gray quartz sandstone, black sand clip, dark gray
