The drill and blast method is one of the most widely used techniques for constructing tunnels in hard rock, where controlled drilling of blast holes, careful charging with explosives, and sequential detonation allow for efficient rock fragmentation and safe excavation. This method requires precise design and execution to minimise vibration, protect surrounding structures, and ensure stability, making it both a challenging and fascinating aspect of tunnelling. If you would like to gain a deeper u

The drill and blast method in tunnelling involves drilling holes in the tunnel face, loading them with explosives, and blasting to break the rock. The broken material is then removed, and ground support like shotcrete or rock bolts is installed. This process is repeated to advance the tunnel.
