六盘山东麓逆冲推覆构造体系在东西方向上具有明显的分带性。通过对推覆体系内韦州-石沟驿、积家井地区的煤层底板标高趋势图和剩余图分析发现：韦州-石沟驿地区位于六盘山逆冲推覆构造带的中带，等值线稀疏，变化缓慢，褶曲形态宽缓，保存比较完整；积家井地区位于六盘山逆冲推覆构造带的锋带，等值线沿北北西向密集排列，褶皱均为紧闭式，断裂尤为发育。上述特征体现了六盘山东麓逆冲推覆构造体系对煤层空间形态的控制作用。

The thrust nappe structure system in eastern foot of Liupanshan Mountains has distinct zoning characteristics. The analyses of coal floor elevation trend and residual plot of Weizhou-Shigouyi and Jijiajing areas within the thrust nappe structure system have found that the Weizhou-Shigouyi area is situated in the central zone of Liupanshan Mountains thrust nappe structural belt with sparse contours, slow changes, and broad and gentle fold forms, rather completely preserved. While the Jijiajing area is situated in the frontal zone with contours densely arranged along NNW direction, folds closed and faults well developed. Above mentioned characteristics have demonstrated that the structure system has controlled coal seam spatial forms.
