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

In the drill and blast method of tunnelling, the process begins with strategically drilling holes into the rock at specific intervals along the tunnel alignment. These holes serve as blast points for explosives. In tunnelling, blasting typically starts from center points and radiates outward. The central blast creates a void, breaking up the core of the material and forming a cavity. The drill and blast method remains a widely employed technique in tunnel construction due to its adaptability to

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.

Drill and blast method is one of the common tunnelling techniques in hard rock. The principle behind the blasting in tunnel is to create a free face at the centre of the tunnel by means of cut holes and then extending the blasting to the full face of tunnel. In simple words, blasting relies on two main factors: 1. shock wave to create cracks in the rock 2. Expansion of gas to move into the cracks to crush the rock. In our online Tunnel Engineering course, you will learn blasting techniques in tu

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.

The drill and blast method is a widely used technique in tunnel construction, especially in hard rock environments. This method involves drilling a series of holes into the rock face, filling them with explosives, and then detonating them to break the rock into manageable pieces. After blasting, the debris, known as muck, is removed. Drill and blast is favoured for its effectiveness in excavating through tough geological conditions, but it requires precise planning and control to minimise vibrat
