河南省西部的禹县境内,发育了一套完整的石炭、二叠纪含煤岩系,煤系地层包括晚石炭世的太原组、早二叠世的山西组和下石盒子组以及晚二叠世的上石盒子组。其中的上石盒子组中发育了华北晚古生代特有的可采煤层。探讨其沉积环境与聚煤特点,显然对了解华北聚煤区南带晚二叠世时的古地理与成煤规律,对进一步开发本区煤炭资源颇有裨益。笔者在一般了解禹县上石盒子组沉积环境的基础上,详细地研究了上石盒子组含主要煤层的
In Yu County of western Henan Province, a complete set of Carboniferous and Permian coal-bearing rocks was developed. Coal-bearing strata include the Taiyuan Formation of the Late Carboniferous, the Early Permian Shanxi Formation and the Lower Shihezi Formation, Stacked on the stone box group. Among them, the Upper Shihezi Formation developed the unique recoverable coal seam of the Late Paleozoic in North China. Exploring the sedimentary environment and characteristics of coal accumulation, it is obvious that it is helpful to understand the paleogeography and coal formation law of the Late Permian in the southern coal belt of North China, and to further develop the coal resources in this area. Based on the general understanding of sedimentary environment of Shangshi box sub-group in Yu County, the author has studied in detail the influence of the main coal seams
