平庄盆地构造控煤规律

平 盆地为晚中生代形成的主体为单壁断陷，局部为双壁断陷盆地，北西西系是主要的成盆期构造，对聚煤起得要的控制作用，盆地西缘的北不向同沉积大断层和盆地北部边缘的南北走向的同沉积断层控制着盆地的形成和发展，盆地内北西西向褶皱控制着盆地的聚煤中心，中新华夏系和北北西系为成盆后构造，它们所形成的褶皱与先期构造叠架构造穹隆或构造盆地，对煤层的埋藏深度起到了控制作用。

Law of Structural Control Coal in Pingzhuang Basin

Pingzhuang basin is a late mesozoic basin, Its main structure is a single-arm fault, and its part is a double-arm fault. The major structure during the basin formation which controls the coal-forming is NWW system. The formation and development is dominated by the contemporaneous fault in the west and north edge of this basin. The fold of NWW direction controls the centre of coal-forming, midolle and new cathaysian system and NNW system is the structure after the basin formed. The fold accummulated with the prefer fold forms the structural dome or structural basin, It also dominates the buried depth of coal seams.
