| 摘 要： | 通许找煤区位于华北板块南缘，属河南分区嵩箕赋煤带，总体而言，区内北部为一近东西向的开封断陷系，南部为周口坳陷系，中部为通许隆起，可谓“两坳夹-隆”。南北坳陷保存了较完整的石炭-二叠系含煤建造，中部隆起区因后期风化剥蚀，使部分含煤岩系缺失，加之后期NW向和N（N）E向断层的切割及两盘的差异升降，导致煤系地层的赋存格局又发生了次级变化．从而使本区呈现东西成带，南北成块的总体面貌，并控制着本区二1煤层的埋深。

| Abstract: | The Tongxu coal looking area is located at the south margin of the North China plate, a part of the Songji coal-bearing zone. Totally, the northern part of the coal-beating zone is the EW trend Kaifeng fault depression; southern part is the Zhoukou depression; while the Tongxu uplift stands in the middle. Rather integrated Permo-Carboniferous coal-bearing formations have preserved in the south and north depressions, uplift in the middle suffered succeeding weathering denudation made hiatus of part coal-beating strata. Additional succeeding dissection by NW and N （N）E trend faults and differential elevation of two fault walls caused secondary variation of coal measures strata hosting pattern, made the area EW zoning and NS blocking, and controlled buried depth of the Ⅱl coal seam in the area. |
