摘要
赣西北地区下二叠统王家铺煤组和上二叠统乐平煤组，形成于陆缘海的湖泊沼泽环境。王家铺煤组属构造中等、煤层极不稳定型，煤质为高硫、低灰份之烟煤；乐平煤组是构造中等、煤层较稳定型，煤质为高硫、高灰份之无烟煤。聚煤作用与原始成煤盆地地形。
The Lower Permian Wangjiapu coal measures and the Upper Permian Leping coal measures in Northwest Jiangxi were formed in lacustrine environment in the epicontinental sea area. The Wangjiapu coal measures are controlled by structure of moderate complexity, and are extremely irregular and composed of bituminous coal with high sulfur and low ash content; whereas the Leping coal measures are relatively regular and are composed of anthracite with high sulfur and high ash content although they are controlled also by structure of moderate complexity. Coal_accumulating process is closely related to the primary landform of the coal-forming basin, the underlying genetic facies and the post coal-forming structure.
