摘要
爆破荷载作用下高陡边坡的动力稳定性分析是一项较为复杂的过程。针对云南省昭通市铅锌矿大明槽高陡边坡下方Ⅰ#矿带开采爆破设计,利用有限元程序进行了边坡爆破过程中位移、速度、应力分布和边坡稳定性的动力分析,结果表明了该开采爆破方案设计是切实可行的,并为以后爆破设计提供了参考依据。
It＇s a complicated process of power stability analysis of high and steep slope under the effect of blasting load. Aim at the mine blasting design of lead-zinc mine No. I ore zone which at lower part of high and steep slope of Damingcao in Zhaotong city of Yunnan province, the drive analysis of displacement,speed,distribution of stress and the stability of slope during the process of slope blasting is done by using of finite element program, the result indicate this mine blasting project design is feasible, and provide reference basis for later blasting design project.
