摘　　要：煤岩层对比工作对于煤田地质勘探、储量计算以及煤炭资源的开发利用都具有极其重要的意义,它是研究含煤地层层序、煤田地质构造、煤层厚度变化、煤层赋存规律的基础工作,是煤田地质勘探工作的主要任务之一.本文采用标志层法、层间距法、煤质特征分析法和测井响应,对本区的主要含煤层段二叠系山西组、上下石盒子组进行了系统的划分和对比,准确确定了主要可采煤层二1煤层和局部可采煤层二2煤层、七2煤层的层位,并对这些煤层的空间展布进行了对比,这一煤岩层对比方案已为煤田勘探和煤矿开采的揭露所证实.The correlation of the Permian coal seams and stratigrapy is very important for coal exploration, resource assessment and coal mining. It is a fundamental work to the investigations of coal-bearing sequence, tectonics and coal distribution. The Permian Shanxi Formation, Xiashihezi Fromation and Shangshihezi Formation are divided and correlated with the methods of typical rock seams, intervals between coal seam and typical rock seam, coal quality and well logging response. The positions of Ⅱ 1 and Ⅶ 2 coal seams are exactly located and the distributions of the coal seams are systematically correlated. The correlation is proved to be correct by coal exploration and coal mining.
