摘要
以工程实践和动力有限元程序分析沟槽深孔微差爆破问题。探讨了沟槽内岩块的运动规律，以及深孔微差爆破的作用机理。结果表明，基于工程实践的数值模拟，能较客观地反映爆破破岩的动态过程，并为爆破设计提供理论依据。
The engineering practice and the numerical simulation have been conducted on the millisecond blasting for ditching deep bore hole.The movement of the rock in ditching and the mechanism of millisecond blasting were analyzed.The results show that the numerical simulation based on the engineering practice can be better revealing the dynamic course of fragmental rock,and helping to the blasting design.
