Abstract: Slope stability influence factors layer structure model was established by combined with practical situation of Shibao iron mine and using analytical hierarchy process. 14 influence factors which effect slope stability were analysis, quantitative calculation and rank, and then consistency check was done. The influence weight of each factors were general ranked, and the main effect factors of slope stability were found out. It can provide basis for maintenance and management of mine slope.

Key words: Analytical hierarchy process, Structure model, Slope stability
