摘要
太行山东麓含煤区以中生代末期以来的伸展构造变形为主导,煤系埋深自西向东逐渐加大,沿太行山前呈NNE向条带状展布。区内构造样式丰富,以NE、NNE向正断层组合为特征。其深部控煤构造样式主要为两类堑垒构造组合和掀斜断块组合两类。通过研究区构造组合的分析,掌握了太行山东麓含煤区煤田构造的特征,为老矿区外围深部找煤提供了依据。
The extension structures formed since the end of Mesozoic are dominant in the eastern foot of Taihang Mts. coal-bearing zone. Coal measures distributed along the eastern foot of Taihang Mts. and deepening from west to east, striped NNE extending. The structure style is varied and characterized by combination of NE-strike normal faults and NNE-strike normal faults. Based on the study of the deep coal measures distribution, two kinds of structural styles that controlled coal has advanced, they are the combination of grabens and horsts and the combination of tilted fault blocks. The structural coal controlling has deepened the understanding of structural characteristics in eastern Taihang mountain foot coal-bearing zone, which provided the new basis for look for coal in the deep part or periphery of old coalmines.
