Abstract
In order to study the impact of dump height on the bearing capacity of the foundation and the slope stability of the external dump,this article analyzes the dump height of No.1 Open-pit Coal Mine in Xinjiang Jianghai Gobi,establishes the composite slope with different dump heights using FLAC3D software for stability analysis.The results show that as the dump height increases,there is a significant vertical displacement and displacement in the direction of the slope surface,with a tendency for shear strain to concentrate on the slope.The stability coefficient gradually decreases.When the dump height reaches 160 m,the influence of external dump on the slope becomes small,and the slope stability coefficient is 1.56,which is higher than the design requirement.The stacking height of the dump can be increased to 160 m.关键词
