SLOPE STABILITY ANALYSIS OF INNER MONGOLIA′S HUOGEQI OPEN PIT COPPER MINE

In this paper, FEM, reliability analysis and limiting equilibrum method are applied to the analysis and assessment of slope stability at Huogeqi Open Pit Copper Mine according to the specific features of engineering geology.The slope angle can be added with a large quantity.In order to increase the slope angle the design of this mine had been altered by means of the results obtained to have been added four degrees.So that the more economic benefits have been gotten.
