Abstract: Based on the basic rock mechanics properties of Xishimen Iron Ore,the simulation on the coupling charge blasting process of the smooth blasting peripheral holes is made by using the finite element numerical simulation software ANSYS/LS-DYNA.In case of getting the normal rockslides meanwhile minimizing the disturbance of the surrounding rock,a more reasonable spacing of the peripheral holes is determined to be 0.6 m,and the efficiency of smooth blasting is improved as well.
