There are many methods of tunnel construction, each requiring specialist skills and equipment. These include techniques such as bored tunnels using Tunnel Boring Machines (TBMs), sprayed concrete lined tunnels, tunnels constructed by blasting with explosives, and tunnels constructed by pipejacking. This large variety means the tunnelling world and the skills it needs are constantly varied and challenging. #tunnelengineering #artoftunnelling #tunnel #tunnelengineeringisthefuture #tunnel #tunnelli

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

Blasting techniques in rock tunnels involve strategically drilling a series of holes into the rock face, which are then filled with explosives. These explosives are detonated in a carefully planned sequence to maximise rock fragmentation and control the shape and size of the tunnel. The flexibility of the drill and blast method in rock tunnels is one of its greatest advantages. It allows for adaptation to varying geological conditions, accommodating changes in rock type, hardness, and structural
