The drill and blast method in tunnelling involves drilling a series of holes in a precise pattern, then filling them with explosives to break and remove rock. The design of the drill and blast pattern is crucial, as it determines the effectiveness and safety of the operation. It factors in rock type, tunnel size, and desired fragmentation. Proper sequencing and timing of blasts are essential to minimise vibration, control overbreak, and maintain the tunnel's structural integrity. Follow us at tu

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.
