This paper takes an open-pit mine as the research object, adopts the three dimensional limit equilibrium method to carry out the stability analysis of the slopes in each area of the mine, realizes the solution of the safety factors of each area through SLOPE2000 software, and further puts forward the suggestions of slope angle optimization. At the same time, the software uses the simulated annealing algorithm to search for the most dangerous sliding surface of slope failure in each area, and a three-dimensional sliding surface model is established by the modeling software and the analysis of it is conducted. The applied research shows that the results obtained by adopting three dimensional limit equilibrium method are more realistic in the calculation of slope stability coefficient of open-pit mine; and the results that the most dangerous sliding surface searched and simulated by the simulated annealing method have certain applicability, which is convenient to guide the correct landslide treatment of slope.
