As more and more large-scale open pit project of construction of open pit slope stability evaluation and more attention. With some large-scale open pit mining depth, the formation of some high and steep slope, slope stability is even more prominent, and how to develop an effective, simple and accurate method to evaluate the slope stability is a problem worthy of study. The past, traditional methods such as geological analysis, numerical analysis, probability analysis, etc. Although these methods were a number of assumptions and simplifications, but it has its shortcomings and limitations, only the combination will be a variety of factors, taken together, can more realistic.Fuzzy Comprehensive Evaluation Method wide range of adaptability, from the perspective of complex object hierarchy, the vector form of the results can be richer than other methods to provide the evaluation of information, open pit slope stability analysis provides a useful guide.In this paper, some basic principles of fuzzy mathematics, fuzzy comprehensive evaluation described the principles, methods, selected fourteen of open pit slope stability analysis of the factors, the establishment of a unified model for open pit slope stability analysis. AHP is given the right to a more objective method of determining the impact of open pit slope stability calculation of the weight of various factors, combined with practical application to the evaluation of open pit slope stability, through the South to help expand Pingzhuang adopted Western Open slope stability analysis to further deepen the understanding of this approach. The idea of fuzzy structuring element, Introduced the basic principles of structuring element and fuzzy linear generating function approach, proposed open pit slope stability improved fuzzy comprehensive evaluation of thinking on the future open pit stability analysis gives a useful exploration.
