In order to solve the problems about section of stratified surrounding rock being difficult to form and excessive or insufficient excavation stratified surrounding rock, the paper used three-dimensional analysis method of FEM to conduct numerical simulation for the stratified surrounding rock of the deep inclined shaft of Bulunkou - Konggur hydropower station. Through analyzing the observation data of the surrounding rock in tunnel face, it got the influence of the highland stress on blasting vibration, the most danger failure zone of the stratified surrounding rock and propagation law of the blasting vibration, and also gave suggestions about excessive or insufficient excavation stratified surrounding rock. The result can provide a way for the construction and design of similar projects.
