摘要： 随着我国露天开采迈入深凹开采阶段，排土场征地难度日益增大，征地成本不断提高，促使排土场向高陡方向发展。高陡排土场的发展虽然减小了土地的征用，减少了矿山的生产成本，但排土场高度的增加也带来了一系列的问题。以河曲旧县露天矿为工程背景，分析其内排土场增高扩容的稳定性。以河曲旧县露天矿内排土场等高线为初始数据，采用Rhino3D快速建立三维模型，同时采用Slope和FLAC3D分析增加不同高度时边坡的稳定性。

Abstract: With the development of openpit mining into deep concave mining stage in China,the difficulty of land acquisition in the drainage field increases day by day,and the cost of land acquisition increases continuously,which promotes the development of the drainage field to a high and steep direction.Although the development of high and steep drainage field reduces the land acquisition and the production cost of the mine,the increase of the height of the drainage field also brings a series of problems.In this study,the stability of the increased and expanded capacity of the inner dump was analyzed with the surface mine in jiuxian county of Hequ county as the engineering background.Rhino3D was used to quickly build a 3D model based on the initial data of the contour line of the drainage field in the open pit mine of hequ county.Meanwhile,Slope and FLAC3D were used to analyze the stability of the slope when different heights were increased.

Key words: open pit mine,dump,Rhino3D software,increased capacity,slope
