【Abstract】 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. [更多还原
