构造煤是煤矿瓦斯灾害防治和煤层气开发的重要研究内容之一,根据对华北板块含煤建造及构造煤层域分布规律的研究,晚古生代时期,受聚煤古地理环境控制,随着成煤时代的推移,成煤环境由北向南逐渐向上迁移,太原组成煤环境主要分布在北部,山西组主要分布在中部,石盒子组完全展布于南部。构造煤的层域分布主要受含煤建造控制,包括煤岩层岩性、厚度及组合,其中,煤层厚度是最主要的控制因素,构造煤主要形成在厚煤层中,如北区主要形成在太原组厚煤层中,中区主要形成在山西组厚煤层中,南区主要形成在石盒子组厚煤层中。
According to the research on coalbed construction and the distribution rule of coal seam in North China Plate, tectonic coal is one of the important research contents in the prevention and control of coal mine gas disasters and coalbed methane development. According to the research on the distribution rule of coal seam in North China Plate in the Late Paleozoic, As time goes by, the coal-forming environment gradually migrates upward from north to south. The coal environment of Taiyuan is mainly distributed in the north, the Shanxi Formation is mainly located in the middle and the Shihezi Formation is fully spread in the south. The stratigraphic distribution of tectonic coal is mainly controlled by the coal-bearing construction, including the lithology, thickness and combination of coal rock formations. The thickness of coal seam is the most important controlling factor. The tectonized coal is mainly formed in thick coal seams, In the thick coal seams, the middle zone is mainly formed in the thick coal seam of Shanxi Formation, and the southern zone is mainly formed in the thick coal seams of Shihezi Formation.
