Case Study of Blasting Pattern Design for Tunnelling in Which Considered Blast Induced Vibration Affected Across Buildings

In generally blasting pattern design is carried out in-situ borehole blasting test and its analysis. We added the 3D numerical analysis for blast induced vibrations. This paper is case study of 3D numerical analysis in which considered blast induced vibration affected across buildings, and then we design the blasting pattern of tunnel excavation.
