Space Properties of Effects of Slope Stability by Underground Mining

At present, technology for open pit combined underground mining is one problem about mine. It mainly involves some problems, such as how to design deep resources exploitation, how to evaluation slope stability and so on. Combining the underground mining effect with their characteristics and function attributes influenced by the slope deformation, this paper considers the both composite superimposed law, and derives the calculation method of the slope stability under comprehensive function. Accordingly, explore the influence law of slope stability, induced by underground mining area and the relative position and the space and geometry size changes of slope body. And the final purpose is to provide the scientific basis for design and safety assessment of deep resource extraction.
