In the drill and blast method of tunnelling, the drilling stage is a crucial step where holes are drilled into the rock face to prepare it for subsequent blasting. This process involves using specialised drilling equipment (usually jumbo drill) to create precisely positioned and sized boreholes in the tunnel excavation. The spacing and depth of these holes are carefully planned to optimise the efficiency of the subsequent blasting operation. Once the holes are drilled, explosives are strategical

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
