福建省二叠纪含煤区深部找煤靶区研究

摘要

According to the Permian Coal Basin stratigraphy, coal accumulation rule, capping coal characteristics and coal accumulation of the structural transformation of the coal-bearing strata on the basis of fundamental understanding, nine typical target areas are selected as the research objects in Fujian Province respectively from under the sliding cover body, under the nappe, under the volcanic rock and red layer to find the coal target area. The results show that the deep Permian coal-bearing area of Fujian Province coal prospects looks good, with a prediction of about 1.15808 billion tons of coal reserves. This study helps relieve the worry of coal shortage and looking for coal in depth is of great significance in Fujian Province.%根据对二叠纪聚煤盆地的层序地层、聚煤规律、煤系盖层特征以及聚煤期后构造对煤系地层改造的基本认识基础上，选取福建省9个典型靶区作为研究对象，分别从滑覆体下、推覆体下、火山岩下及红层下出发寻找煤靶区。结果表明福建省二叠纪含煤区深部找煤前景较好，预测煤炭资源量约115808万t。该研究对缓解福建省煤炭缺口以及深部找煤均具有重要意义。
