织金县三塘向斜煤系地层沉积特征分析

Analysis on Sedimentary Characteristics of Coal Measure Strata in Santang Syncline of Zhijin County

本文通过对贵州省织金县三塘向斜煤炭整装勘查区内煤系地层各含煤段的沉积地层层序特征、岩性组合特征、层理构造、层面构造、生物遗迹特征等原生地层沉积特征、古地理环境及沉积相的综合分析和研究,得出了研究区内煤层的成煤规律及赋存状态,针对煤炭资源勘查工作中的初期找煤阶段,确立了找煤工作时期的理论模式,为今后找煤方向提供了依据。

Based on the comprehensive analysis and research on the sedimentary sequence characteristics,lithologic combination characteristics,bedding structure,bedding structure,biological trace characteristics,paleogeographic environment and sedimentary facies of each coal bearing section of coal measure strata in Santang syncline coal integrated exploration area,Zhijin County,Guizhou Province,this paper obtains the coal forming law and occurrence state of coal seams in the study area.Aiming at the initial stage of coal prospecting in coal resource exploration,the theoretical model of coal prospecting period is established,which provides the basis for the future coal prospecting direction.
