摘　　要：以新一轮全国煤炭资源潜力评价东北地区资料为基础,参考区域地质和能源盆地研究的最新成果,分析了东北地区煤田构造的主要特征,聚煤盆地多为半地堑、地堑性质的断陷盆地,盆地的形成与火山活动关系密切,展布方向主要为北东和北北东向。根据东北地区煤系赋存特征、构造格局,确定了东北赋煤区的边界,应用赋煤构造单元的理论,将东北赋煤区划分为11个赋煤构造带,系统论述了各个赋煤构造带的基底性质、盆地构造和控煤基本特征。On the basis of a new round of Northeast China potential evaluation on coal resources, and reference to the latest achievements about regional geological and energy basins, the article analyzed the main features of the Northeast China coalfield structure. Most coal basins were half-graben, graben basin and mainly trend NE and NNE direction, which formation was closely related with volcanic activity. The article identified the boundary of Northeast China coal occurrence area according to coal occurrence features and structural pattern.Application of the theory of coal occurrence tectonic units, Northeast China coal occurrence area was divided into 11 coal occurrence tectonic zones. The article systemically discussed the basic characteristics of the nature of the basement, basin structure and coal-control of each coal occurrence tectonic zone.
