山东省阳谷-茌平煤田煤层对比研究

Comparative Study on Coal Strata in Yanggu-Chiping Coalfield in Shandong Province

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 combination 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 section,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 combination 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.
