红格尔矿区位于额合宝力格复向斜内,含煤层为白垩系下统巴彦花组中段[1]。煤层主要赋存在复向斜的次级向斜中。分析认为额合宝力格煤田形成过程为:早期断陷型盆地,随着地壳活动的变缓,基底下沉,转为坳陷型湖相沉积环境,经淤浅后成为浅湖～沼泽相,在具备相对稳定的古环境下下,形成含煤岩段及煤层。通过对煤田赋存状态的分析,了解了其形成和分布规律,为科学找煤,资源前景预测提供依据。
The Hongleer deposit is located in the amount of Baolige syncline and the coal seam is in the middle of the Bayanghuai Formation under the Cretaceous [1]. The coal seam mainly exists in the secondary syncline of the syncline. The analysis shows that the formation process of Baolige coalfield is that in the early fault basin, with the slowening of crustal activity, the basement subsidence turned into a depressing lacustrine depositional environment, which became shallow lacustrine-swamp phase , In a relatively stable ancient environment, the formation of coal-bearing rock and coal seam. By analyzing the occurrence state of the coalfield, we know the formation and distribution of coalfields, and provide the basis for the scientific prospecting of coal and resources.
