Abstract: The hanging wall ore of the open-pit is one of important projects in transition from open pit to underground in Daye iron mine，and the shallow hole shrinkage mining method is adopted in the project.In this paper，to consider the impact of fault F9，the stope layout techniques are analyzed in the process of development and mining of hanging wall ore.By the analysis of disturbance of landslide due to the mining of hanging wall ore，the height of the empty area and the size of the exposed area and the pillar between empty area should be focused specially in the mining process to ensure the security and stability of the slope and landslide.
