摘    要:阜新盆地属于晚中生代NNE向地堑式煤盆地。北西西系是成盆期的构造和同沉积构造,对盆地聚煤起最主要的控制作用;盆地中三个聚煤期与规模较大的WNW—NW向断层有关。而盆内中央断隆带内部的WNW—NW向背斜构造则控制着各时期的聚煤中心。中晚新华夏系是成盆后构造,它的NNE—NE向背斜构造与北西西系的WNW—NW向背斜构造叠加复合所形成的构造穹隆或短轴背斜控制盆地露天开采煤层。

关 键 词:控煤构造  煤矿床  阜新盆地  煤系  聚煤期

COAL-CONTROLLING STRUCTURES IN THE FUXIN BASIN

Abstract:The Fuxin basin is a late Mesozoic NNE-trending graben coal-bearing basin. The NNW structural system is considered to be synbasinal and syndepositional structures, which appear exert the most important controlling effects on coal accumulation in the basin. Relatively large WNW-NW-trending faults seem controll the occurrence of three coal-accumulating stages, while WNW-NW-trending anticlines inside the central fault may controll the coal-accumulating centres and districts. The middle and late Neocathaysian structural system is postdepositional structures. The structural domes or short-axis anticlines formed by compounding and ovelapping of the NNE-NE and WNW-NW-trending folds may controlled the opencut mining of coal beds in the basin.
Keywords:coal-controlling structure  WNW structural system  Neocathaysian system  Fuxin basin
