摘要
研究区位于内蒙古自治区阿拉善左旗南部,区域构造位置处于贺兰山深断裂南段与牛首山固原深断裂交汇处的贺兰山复向斜带内。主要含煤地层为侏罗系延安组,含可采煤层2层,属较稳定煤层。通过对研究区含煤地层的沉积特征分析,阐明了含煤岩系的沉积环境。
The study area is located in the southern of Alxa left Banner, Inner Mongolia, the regional tectonic position in Helan Mountain syneline ,interehange in the southern part of Helan Mountain deep fault and Niushoushan - Guyuan deep fault . Jurassic Yanan group is the principal coal bearing strata, containing most of ruinable seam 2 layers, belong to the stability of coal seam. Abstract through the analysis on sedimentary characteristics of the main coal - bearing System, this paper illustrates the sedimentary environment.
