摘要
本文利用 ADINA有限元程序对三维切槽孔、圆形孔爆破作了弹塑性数值分析 ,结果表明三维切槽孔爆破的破岩半径远大于圆形孔爆破 。
The elasto-plastic numerical analysis on 3-D slotted or circular hole blasting was carried out by the ADINA finite element program. The results show that the radius of broken rock by 3-D slotted hole blasting is much larger than that by circular hole blasting. Thus, they offer a basis for numerical analysis on 3-D slotted hole blasting method. [
