摘要
通过分析爆破试验结果，建立了以成梁假设为基础的宽孔距爆破破碎机理模型。提出了以孔间裂缝扩展速度Ｖｐ和裂缝扩宽速度Ｖｓ表达的岩石破坏准则。
In this paper,the results of blasting are analysised and a new fragmentation mechanism model based on the hypothesis of forming beam for the blasting of large spacing and small burden and the destroy criterion expressed by v P (crack development velocity between blastholes) and v s (crack widening velocity) are suggested.The mechanism model is proved correct through the test study as well.
