通过对“Ｖ”型切槽爆破断裂成缝机理的分析研究和模拟对比计算， 提出了切槽尖端动态应力集中和“Ｖ”型切槽尖端附近区域裂缝生成抑制联合作用的断裂成缝机理。
Based on the analysis of the mechanism of the “V” slotted burst fracture and the comparative calculation of the simulation results, the fracture mechanism of the fracture is put forward based on the combination of the dynamic stress concentration at the slotted tip and the suppression of cracks in the vicinity of the tip of the V-shaped slot.
