摘　　要：准格尔是国家规划矿区位于鄂尔多斯地台东北缘,晚古生代以来沉积了多套发育良好的含煤地层,太原组就是其中之一。从空间展布特征来看矿区内太原组分为上下两层主要含煤层位,上部6#巨厚煤层分布范围也大于下部9#煤层,但由于在沉积过程中分流河道侧向迁移或改道频繁,使其在南、北方向上多次分岔。Taiyuan formation is one of the coal-bearing stratum deposited since late Paleozoic in Zhungeer national planning coalfield which located in the northeastern margin of Ordos platform.From the spatial distribution characteristics,Taiyuan formation in the area is divided into two layers of main coal seam.The upper coal seam 6# is both thicker and wider than the coal seam 9#,but it is multiple bifurcation in the south and north direction because the distributary channels lateral migrated or diverted frequently during the deposition.
