Results indicate that the residual stress is useful to form the cracks between the shot-holes for smooth blasting, but not for pre-split blasting.
结果为:原岩应力的存在有利于光面爆破的炮孔间贯通裂纹的形成,不利于预裂爆破的炮孔间贯通裂纹的形成。

If the same holes were built today, many golfers would criticize the fourth hole for its blind tee shot, which even Dr.
如果今天在建造同样的球洞,很多球手都会批评四号洞的盲打,甚至麦肯齐博士也会承认它不太理想。

Based on the theory of dynamic fracture mechanics, the mechanism of crack-forming among shotholes in the directional split of rock by controlled blasting is expounded.
