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

The drill and blast method is a highly flexible technique widely used for constructing tunnels in rock. It involves drilling holes into the rock, filling them with explosives, and detonating to break the rock into manageable pieces. This method is particularly adaptable to varying rock conditions and complex tunnel geometries.
