A case study on tunnel blasting design evaluation considering blast damage zone

Hard rock tunnel blasting becomes more efficient with the state-of-the-art technology advancements of the computeraided drilling machine which minimises the drilling error. However, overbreak is still considered as the primary challenge of any tunnelling project using drilling and blasting methods....
