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.

Another great blasting! Drilling and blasting is a core method in mining, vital for extracting minerals from the earth. It involves drilling holes into the rock face and strategically placing explosives to fracture the rock for extraction. Courtesy of Bam Ritchie drill and blast.

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

The drill and blast method can be used for constructing shafts in rock, similar to its use in tunnelling. In both cases, explosives are placed in drilled holes to fracture the rock, allowing for excavation. However, in shaft construction, the drilled holes are oriented vertically downward, whereas in tunneling, they are drilled horizontally. Despite this difference in drilling direction, the underlying principle remains the same: controlled blasting breaks the rock into manageable pieces for rem
