Abstract
In surface mining, it is very important to create a mining area for economical mining. This study examined the contribution of design factors on slope stability with different slope design and blasting conditions. The design factors were the properties of the rock, the slope angle and the bench height, and the blasting conditions were reflected at different explosive weight and distances. The safety factor of slope was calculated by shear strength reduction method through 3D modeling, and the contribution rate of rock slope was 94.8%, which is relatively higher than other design factors, slope angle 0.89%, bench height 0.58%, and blasting It is shown that it affects about 3.73%, and it can be seen that blasting at a close distance can affect the stability of the slope.
