浅析乔家湾矿区山西和太原组煤层聚煤规律及其沉积环境的变化

Analysis on the Coal-accumulating Regulation of the Coal-seams of Shanxi Group and Taiyuan Group in Jiangjiawan Mining Area and the Variation of Their Depositional Environment

分析了乔家湾矿区山西、太原组的岩层及古生物化石特征、煤岩性特征、煤层结构特征、煤质特征以及山西、太原组的煤层聚煤规律及沉积环境,指出1号、2号煤层为滨海—三角洲平原沉积,9号、10号、11号煤层为三角洲海湾及碳酸盐台地沉积,从中找出它们的变化规律性,对今后的矿井建设有指导意义。

This paper analyzes on the rock-stratum characters, coal lithologic characters, coal-seam structural characters and coal quality characters of Shanxi Group and Taiyuan Group in Jiangjiawan Mining Area and the coal-seam's coal-accumulating regulation and depositional environment of the two groups, and points out that No.1 and No.2 coal-seams are the littoral deposit-delta-plane deposit, and No.9, No.10 and No.11 coal-seams are the delta golf and carbonate platform deposit, from which their varying regulations can be found out for guiding the future construction of the coal mine.
