论述了兖州煤田太原组主要成因相的特征和沉积组合类型，分析了富煤带的形成、分布及其与下伏成因相的关系，也分析了海平面变化对成因相的影响和沉积体系的演化方向，并利用标志层划分了分析单元（相当于层序地层中的Ｐａｒａｓｅｑｕｅｎｃｅ），以单元为分析和编图的基本单位研究了兖州煤田的聚煤规律
The main facies facies characteristics and sedimentary assemblages of the Taiyuan Formation in Yanzhou coalfield are discussed. The formation and distribution of coal-rich belts and their relationship with the underlying facies are also analyzed. The effects of sea level changes on the facies facies and sedimentary system Evolution direction, and divided the analysis unit (equivalent to Parasequence in the sequence stratigraphy) with the marker layer, and studied the law of coal accumulation in Yanzhou coalfield with the unit as the basic unit for analysis and coding
