Abstract
The measures for environmental regulations have become more strict over the recent years. Due to vibration and noise arising from blasting, every site that chooses to handle explosives has to be under certain restrictions in its use. Especially a site where a safety thing is situated within close proximity, the chosen method is through mechanical excavation. However, various applications of electronic detonators has made blasting possible where mechanical excavation used to be the only alternative. Hanwha Corporation has developed an electronic detonator, $HiTRONIC^{TM}$, which is an advanced fourth-generation detonator with a high accuracy of delay time(0.01%). At this moment, $HiTRONIC^{TM}$ is widely used in highway and railway construction sites, large limestone quarries, and many other blasting sites where blasting had not been an available option before. In this paper, I would like to introduce a case study on construction of utilizing $HiTRONIC^{TM}$ at a large-scale tunnel site.
