本文以宣钢近北庄铁矿为例，深入分析了向斜构造对露采边坡稳定性的控制作用。向斜构造特征主要控制影响边坡稳定的主导因素；向斜构造与采场的几何组合关系控制着结构面和岩体结构的力学效应。这种控制规律对同类矿山的边坡研究具有重要的借鉴意义。 In this paper, taking the example of the near Beizhuang Iron Mine in Xuanhua Iron and Steel Co., Ltd., the controlling role of the syncline structure to the stability of the exposed mining slope is deeply analyzed. The structural features of the syncline mainly control the dominant factors that affect the stability of the slope. The geometrical combination of the syncline structure and the stope controls the mechanical effect of the structural plane and the rock mass structure. This control law has the important reference significance to the slope research of similar mine.
