基于ANSYS/LS-DYNA的井巷掘进掏槽爆破扩腔过程的数值模拟

摘要

为了更好的研究爆破作用机理，了解井巷掘进过程中掏槽爆破的爆破效果，本文以两个掏槽孔同段反向起爆的爆破过程为例，利用有限元软件 ANSYS/LS-DYNA 对其爆破扩腔过程进行数值仿真，得到爆破空腔的形成过程，清晰的展示在不同时刻的应力、变形情况，为爆破工艺的进一步优化及实验提供一定的依据。%In order to better study the blasting mechanism,to understanding the blasting effect of cut blasting in the process of roadway drivage. This article take the blasting process of two sections cut hole with reverse detonation for example,using the finite element software ANSYS/LS-DYNA on blasting cavity expansion process numerical simulation,get the blasting cavity formation process,Clearly show in different moments of stress, deformation, blasting technology for further optimization and experiments provide a certain basis.
