Drill and blast method remains a cornerstone in the construction of rock tunnels, leveraging controlled explosions to efficiently break and remove rock. This technique involves precise drilling of blast holes, strategic placement of explosives, and careful detonation to ensure optimal fragmentation and minimal disturbance to surrounding structures. Its adaptability to various rock conditions and cost-effectiveness continues to make it a popular choice in modern tunnelling projects. To gain a dee

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

Watch the moment the tunnel boring machine completes its underground journey and the new watermain reaches the exit point. Installing the watermain underground helps reduce disruptions and keeps the project moving safely and efficiently.
