摘要
根据近年来在研究区进行的煤炭地质勘查资料,从地质、沉积、构造及其演化等方面进行了分析研究,认为本区的煤层主要受控于同沉积构造、差异压实、古基底隆起、成煤后燕山运动第Ⅲ、Ⅳ幕改造等多种因素。
According to the coal geological exploration data in the south of Lingtai county,the coal-controlling factors were comprehensively analyzed from the aspects of geology,sedimentary,structure and its evolution. The study shows that the coal seams are mainly controlled by the syndepositional structure,differential compaction,ancient basement uplift,the transformation of the third and fourth stage of Yanshan movement.
