摘要
煤岩层对比工作是研究煤系地层层序、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。登封煤田区内广泛发育石炭—二叠纪含煤岩系,早二叠世山西组为主要含煤地层。为指导勘探施工,提高勘探质量,在野外进行岩心编录的基础上,针对登封煤田庞窑详查区内的岩心柱状图采用沉积相、标志层、煤层等多种方法对含煤岩系的煤岩层进行了综合对比既指导了登封煤田庞窑详查区内的施工,加快了勘探速度,且有助于整个登封煤田成煤环境的研究及相邻井田的煤岩层对比。
The contrast of coal seams and rock strata is a basic work to research into a coal-bearing strata series,a geology structure of coal field, the thickness variation and occurrence laws of coal seams. It is one of the principal task of coal geology and exploration. There developed extensively carboniferous-permian coal-bearing strata in Dengfeng coalfield, upper Permian Shanxi Formation is the main coal-bearing strata. To guide the construction of exploration and improve the quality of exploration, based on practical core catalog in the field, a comprehensive comparison was carried out between coal seam and rock strata on structural column of this region by means of the sedimentary facies,marker beds,coal seams and other methods. Results have guided the exploration work,improved the rate of explora- tion in Pangyao detailed investigation region, and are helpful to the research on environment of forming coal seams in the whole coal field and the comparison of coal seams and rock strata.
