摘要
利用西石门铁矿的基本岩体力学特性,通过有限元数值模拟软件ANSYS/LS-DYNA对光面爆破周边眼的耦合装药爆破过程进行模拟,在能对岩石正常崩落的同时尽可能减小对围岩的扰动,得出了较为合理的周边眼的炮孔间距为0.6 m,提高了光面爆破的效率。
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.
