摘　　要：本文研究了不同构造样式和构造沉降对聚煤的控制作用。研究发现,含煤地层与煤层累积厚度彼此之间存在着一定的内在联系,盆地(凹陷)构造沉降与煤层发育主要表现为3种相关关系,并以琼东南盆地崖南凹陷西部缓坡、鄂尔多斯盆地黄陇侏罗纪煤田、阜新盆地王家营子区海州组煤层为例,对这3种相关关系进行分析研究。The control effect of different structural styles and structural subsidence on coal accumulation were studied,found that there is a certain internal relationship between the coal-bearing strata and the cumulative thickness of the coal seams. Basin(sag) tectonic subsidence and coal seam development are mainly manifested in three correlations. The relationship is based on the western gentle slope of Yanan in Qiongdongnan Basin and Ordos Basin. As an example, the Jurassic coal field in Huanglong and the coal seams of Haizhou Formation in Wangjiayingzi District of Fuxin Basin were used to analyze and study these three correlations.
