Scaling is an important stage in drilling and blasting method in rock tunnels. After each blasting scaling must always be carried out in order to remove any loose rocks. An example of mechanical scaling and chiseling is shown here during the construction of the tunnel in Tamoios highway and tunnel project in Brazil.

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
