在湖南中部有一系列呈斜列状弧形展布的含煤向斜,其露头形态多样各别。为揭示其成因,我们选定其中之一的保和堂向斜,对它进行了褶皱构造分析,试图通过研究褶皱形态、位态以及与褶皱迭加作用的关系,藉而达到解释露头形态、褶皱变形的演化历史及褶皱迭加作用对煤层的影响。鉴于研究褶皱的迭加作用在煤田里是初次尝试,在本区又不可能测出可供利用的轴面劈理和能指示应力方位的构造线理等宏观标志。因此,不确定因素尚多,难免有错,敬请指正。 In central Hunan, there are a series of coal-bearing synclines distributed in an arc of a curve, with various forms of outcrops. In order to reveal its causes, we selected one of the Baohentang anticlines and analyzed the fold structure of the Baohentang anticline, attempting to explain the outcrop pattern by studying the relationship between the fold shape, The evolutionary history of fold deformation and the effect of fold superimposition on the coal seam. In view of the first attempt to study the superimposition of folds in coal fields, it is not possible to detect macroscopic markers such as the available available axial cleavage and tectonic anomalies that can indicate the orientation of stress in this area. Therefore, uncertainties are still many, it is inevitable that, please correct me.
