摘要
赣西长-西向斜煤田位于萍乐坳陷带西段,长西向斜的煤系地层属晚二叠世海陆交互相含煤建造。基于萍乡长西向斜含煤地层岩芯、测井等资料,结合乐平煤系岩石特征、煤质特征、沙泥比和层序地层格架研究该煤田的沉积环境、岩相古地理和聚煤规律,对莲花长-西向斜乃至萍乡乐平煤系找煤方向及成煤预测都有重要指导意义。
Xiaojiang coal fieldis located in changbu-xiyunshan syncline of the western Pingle sag in Lianhua county, Jiangxi province, and it＇s coal measure strata is the Late Permian paralic coal formation. Base on the data of coal-beating strata core, logging and etc., binding the lithology characteristics, coal quality characteristics, sand/mud rate and sequence stratigraphy framework, research on the coal field sedimentary environment, lithofacies paleogeography, and coal-forming rule have important governing significance in the aspects of coal-survey direction and coal-forming prediction for the Xiaojiang coal field even the Pingle coal formation.
