| 摘 要： | 利用ANSYS/LS-DYNA软件,采用数值计算方法,从不同起爆方向,对单孔柱状连续装药爆破对孔壁岩石的影响作了比较分析,得出一些有参考价值的结论。岩石爆破时,应尽量采用反向起爆方式,充分利用炸药能量,减少爆破对岩石造成的损伤。

| Abstract: | By using the ANSYS/LS-DYNA analysis software and numerical calculation method,and on the basis of different initiation directions,the effect of single column continuous charge on rocks around blast hole blasting was analized and some valuable conclusions were drawn.When rocks were blasted,reverse detonating should be tried to use,explosives should be utilized,and the damage of rock blasting should be reduced. |
