| 摘 要： | 通过对大量钻孔资料分析，运用沉积学、煤田地质学的基本理论和方法，分析了淮北煤田刘店井田二叠系下统山西组和下石盒子组的沉积环境和成煤演化史。研究表明，山西组和下石盒子组煤层都形成于三角洲平原环境，其中，山西组煤组形成于三角洲低速度的建设与高速度的建设的过渡时期；下石盒子组煤组形成于高速度建设型的三角洲平原环境。运用标志层、层间距、煤层顶底板岩石特征、煤质特征、微量元素地球化学特征等综合分析方法，对7、10煤层进行了对比判定。

| Abstract: | Applying the principle and method of sedimentology and coal geology, based on the detailed coring data analysis,the sedimentary environment and evolution history of coals formed in the Liudian minefield, Huaibei coalfield were analyzed.The results showed that coals of the Shanxi Formation and Xiashihezi Formation were both developed in the environment of delta plain,coal seams of Shanxi Formation were formed in the transitional period of the delta in low-speed and high-speed constructions,while coal seams of Xiashihezi Formation was formed in high-speed construction delta plain environment.The marker beds, spacing of layers, lithology of coal roof and floor, coal quality and trace element in coals are all used in correlation of main minable Nos. 7 and 10 coal seams. |
