摘 要 比德－三塘盆地煤体结构受构造作用影响明显，通过对比分析盆地煤体结构与构造形态、构造曲率
在区域上的分布特征，发现同一构造形态中构造应力集中的地区，构造曲率较大，煤层受破坏程度较大；构
造应力松弛的部位，构造曲率较小，往往煤体结构比较完整。因此，可以通过构造曲率大小反映构造应力状
态和裂隙发育情况，从而预测煤层煤体结构的发育程度。

Abstract: The coal structure in Bide-Santang basin is obviously affected by tectonic action. Through comparative
analysis of the regional distribution characteristics of coal structure, structural form and structural curvature in the basin,
it is found that the area with concentrated tectonic stress in the same structural form has larger structural curvature
and larger damage degree of coal seam; the area with relaxed tectonic stress has smaller structural curvature and more
complete coal structure. Therefor
