🟢 🚧 Drill and blast remains a versatile excavation method for variable rock masses where mechanised methods are unsuitable. Effective delivery depends on a thorough geotechnical investigation and geomechanical assessment, a defensible blast design subject to independent review, and the coordinated provision of temporary support and permanent lining (for example shotcrete, rock bolts or cast concrete) as required by ground conditions.

Drill and blast method is one of the common tunnelling techniques in hard rock. The principle behind the blasting in tunnel is to create free face at the centre of tunnel by means of cut holes and then extending the blasting to 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. #tunnelengineering #tunnelengineer #blasting #drillandblast #mechanizedtunnelling #blast #d

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.
