对唐古拉山赋煤带的煤田分布特征、成煤环境及控煤构造进行研究,认为乌丽煤田主要含煤地层为上二叠统乌丽群那益雄组(P3n)和拉布查日组(P3l),扎曲煤田含煤地层为下石炭统俄群尕组(C1e),通过分析区域石炭纪及二叠纪古地理特征,表明煤田成煤环境为潮坪中的泥炭沼泽相环境,繁盛的植被、区域构造运动的减弱和湖盆水体的缓慢退却都是聚煤的主要因素。两煤田控煤构造均为褶皱断裂型,煤层发育在复向斜两翼的次级背斜中,NW向的逆断层控制着褶皱及煤层的展布形态,NW-SW向断裂多对煤层起破坏作用。
Based on the study on coalfield distribution characteristics, coal-forming environment and coal-controlling structure in the coal belt of Tanggula Mountain, it is concluded that the main coal-bearing strata in Wuli Coalfield are the Upper Permian Ulrich Nai-Yixiong Group (P3n) P3l). The coal-bearing strata in Zhaqu Coalfield is the Lower Carboniferous Group (C1e). By analyzing the Paleo-Carboniferous and Permian paleogeographical features, it shows that the coal-forming environment in the coal field is the peat swamp phase environment in the tidal flat, Of the vegetation, the weakening of regional tectonic movement and the slow retreat of lake water are the main factors of coal accumulation. The coal control structures in both coalfields are fold-fractured. The coal seams are developed in the secondary anticlines of the syncline and two wings. The NW-trending reverse faults control the distribution of folds and coal seams. NW-SW faults rupture pairs of coal seams effect.
