本文从动态地层学观点，以山西霍县矿区为例编制的一系列煤岩层厚度等值线图，重演了该区晚石炭世至早二叠世的地质演化历史，并探讨了含煤盆地构造发育的继承性。在此基础上进一步阐述了该区砂体对其上煤层中灰分的控制作用，即煤层中的高灰区与下伏砂体常处于错位关系，高灰区的形成是与流经成煤泥炭沼泽并带入其中的细碎屑悬浮物的潜流量较多有关。

In this paper, from the perspective of dynamic stratigraphy, a series of contour maps of coal seam thickness prepared by the Huoxian mine in Shanxi Province are used to recreate the geological evolution history of the Late Carboniferous to Early Permian in this area. The geological structure of coal-bearing basins Inheritance of development. On this basis, the author further elaborates the control effect of the sand body on the ash content in the upper coal seam, that is, the high ash zone in the coal seam is often in a dislocation relationship with the underlying sand body. The formation of the high ash zone is related to the flow through the peat The marsh and into which the fine debris suspended sediment flow more relevant.
