试论苏邦煤矿区逆冲断层之成因机制及其控煤作用

Discussion on genetic mechanism of reverse thrust and its coal-controlling effect in Subang coal mining area

  • 摘要: 苏邦煤矿区F106断层的成因机制及控煤作用,不同学者对其认识不一。从该断层的特征结合区域构造背景来分析,印支期的滑覆运动应是其主要成因。其后的早、晚期侧向挤压形成现在所看到的逆掩推覆构造。由于其上盘的含煤地层滑动系统经过多期次构造运动的破坏已失去勘探价值,而其下盘的含煤地层相对保存完整,应为主要勘探对象。同时,根据这一成因机制分析指出了外围及新区的找煤方向。

     

    Abstract: Different authors have different opinions on the genetic mechanism and coal-controlling effect of the F 106 reverse thrust in the Subang coal mining area, Fujian. From the view of characteristics of the thrust as well as regional tectonic setting, its main genesis should be the Indo-Chinese Epoch gliding napping. The following earlier and later stages lateral compression formed the thrust nappe structure, which can be observed at present. Since the hanging wall coal-bearing gliding system suffered multiple stages of structural destructions, already has no explorative value, while the footwall coal-bearing strata are relatively preserved intact, and should be regarded as the main exploration target. Meanwhile, the paper also points out the coal prospecting orientation in the periphery of the mining area and prospective coalfield.
