| 摘 要： | 在分析区域构造演化的基础上，结合地质勘查资料，系统分析了冀东南隐伏区构造对煤层赋存的控制机理。研究结果表明，太行山中、新生代以来的伸展隆升作用，导致了研究区以正断层及其组合为主要特征的构造类型的发育。这些构造切割煤层，不仅使煤层的连续性受到了破坏，并且使煤层埋藏深度加大，导致绝大部分区域的煤层失去了勘查意义；但具有中坳新隆构造演化特征的区域，石炭-二叠系分布广、厚度大，是最理想的勘查预测区。

| Abstract: | Based on the analysis of tectonic evolution, combined with systematic research of geological exploration data, the structural control mechanism of coalbeds in southeastern Hebei perdu area has been discussed. The research result shows that the Taihang Mountain Mesozoic and Cenozoic extension and uplifting conduced development of normal fault and its combination characterized structural types. These coalbed cut structures not only destroyed their continuity, but also deepening buried depth and made most part of the area no exploration value. Only the regions with structural evolution characterized by Mesozoic depression and Cenozoic uplifting are optimal exploration and prediction areas where thick Permo-Carboniferous vastly distributed. |
