In tunnel construction, we distinguish between two excavation methods: blasting and mechanized tunneling using tunnel boring machines (TBMs). The choice of drilling method depends on various factors – for example. the length of the road, the nature of the rocks, the economic planning conditions and the proposed construction period.
