Abstract
This paper introduce a multistage parallel non-vibration electronic tunnel blasting cases which adapts Electronic Blasting System(EBS) and the center-cut blasting method to excavating a single line railway tunnel close to residential area. As a result, it was revealed that the vibration and noise showed a reduction of 23.5% and 75% of compared with the allowable standard. We successfully completed the tunnel excavation with decreasing construction time and construction cost and without civil compliant.
