滕南、大屯矿区石炭二叠纪含煤岩系山西组是由三角洲沉积体系单元构成的１个成因地层单位，可进一步划分为３个生长层序，代表了河控三角洲进积浅水海湾的充填过程。２条北西－南东向主分流河道是本区沉积体系单元配置及其演化的控制因素，泥炭沼泽主要发育于分流间洼地。决口扇、子三角洲朵体的建设和废弃在很大程度上支配了泥炭沼泽发育的范围和泥炭堆积的过程，是造成本区煤层分叉的基本动力机制。根据煤岩类型组合和地球化学参数可将主采煤层区分为有序的成因层序，大体反映了泥炭沼泽的充水动态过程。
The Carboniferous Permian coal-bearing series in the Tengnan and Datun coal mines Shanxi Formation is a genetic strata unit composed of sedimentary system units in the delta. It can be further divided into three growth sequences, representing the formation of the shallow gulf in the controlled river delta Filling process. Two North-South-East main distributary channels are the controlling factors of the unit configuration and its evolution in the sedimentary system in this area. The peat swamp mainly develops in the shunt depression. The construction and abandonment of the breaching fan and the sub-delta body largely dominated the development of peat swamps and the process of peat accumulation, which is the basic dynamic mechanism for the bifurcation of coal seams in this area. According to coal type and geochemical parameters, the main coal seams can be divided into ordered genetic sequences, which generally reflect the dynamic process of water filling in peat bogs.
