Drill and Blast Method

Before the blasting takes place, the drilling rig bores the drill holes – determined in advance in a blasting plan – in the foremst front wall of the tunnel (working face). The more solid the rock, the more explosives are required. A jumbo is used to drill holes in the rock face.

Drilling and Blasting Technical Aspects of

Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining ...
