淮南爆田位于华北石炭二迭纪巨型聚煤坳陷的东南隅,由于它所处的构造部位和沉积环境的特殊性,所以太原组有它本身的特点。 本区太原组的厚度为100—120米,假整合于奥陶系之上,与上覆的山西组为逐渐过渡。岩性主要为石灰岩、砂岩和粉砂质泥岩等组成,中夹炭质泥岩和煤层。煤系中有13层灰岩,从上到下编号为L_1—L_13,厚50— Located in the southeast corner of the Permian Jurassic coal-rich depression in the Carboniferous, North China, Huainanbaotian has its own characteristics because of the particularity of its tectonic setting and sedimentary environment. The Taiyuan Formation in this area has a thickness of 100-120 meters, and is fakely integrated with the Ordovician. It gradually transits with the overlying Shanxi Formation. Lithology is mainly composed of limestone, sandstone and silty mudstone, etc., in the folder of carbonaceous mudstone and coal seam. There are 13 layers of limestone in the coal series, numbered L_1-L_13 from top to bottom and 50-
