山东省阳谷茌平煤田煤层对比研究

             

摘要

利用阳谷茌平煤田内的聊城勘查区、阿城镇勘查区、阳谷勘查区、博平勘查区的钻孔资料及地质成果,主要从煤层组合关系、标志层方面对煤田内各勘查区的煤层进行横向比对。山西组发育2~5层煤,3煤发育稳定,厚度较大,易于对比;太原组发育13~17层煤,根据沉积旋回性及赋煤特征分为上组煤、中组煤和下组煤,太原组有3层全区发育稳定的灰岩层,可作为该煤系地层的标志层。同时结合煤层间距及相邻岩层的岩性组合关系,找出各勘查区煤层的对应关系,并提出了统一编号的方案,为该煤田的煤炭资源储量的核实统计及地质综合研究带来方便。%By using exploration drilling data aand geological results of Liaocheng exploration area,Yanggu exploration area and Boping exploration area in Yanggu Chiping coalfield,from the aspects of strata com-bination relations and marker bed,coal strata of each exploration area in coalfield have been compared in horizontal.There are 2 ~5 lcoal ayers developed in Shanxi formation.No.3 coal layer developed stably with large thickness and easy to contrast.There are 13 ~17 coal layers developed in Taiyuan formation. According to sedimentary cycles and coal bearing characteristics,it can be divided into the upper coal sec-tion,middle coal section and lower coal section.There are 3 layers of limestone in the region with stalbe development.It can be used as the marker bed of the coal strata.Combining with the lithology combina-tion between spacing and adjacent coal strata,the corresponding relationship of each coal exploration strata have been found out,and a unified numbering scheme has been put forward.It will bring convenience for the verification of statistical work of coal resources reserves and carrying out comprehensive geological study in the coal field.
