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.
As the name suggests, drilling and blasting works as follows: A number of holes are drilled into the rock, which are then filled with explosives. Detonating the explosive causes the rock to collapse. Rubble is removed and the new tunnel surface is reinforced. Repeating these steps until desired excavation is complete.Drill and Blast Tunneling Practices - CTT consulting,ting discs. The drill and blast technology has a medium cost ef-ﬁciency in the case of tunnels having a length of more than three kilometers, and this cost efﬁciency decreases as tunnel length increases. Drilling and blasting has high unused efﬁciency poten-tial in regard to simultaneous cyclic work and logistic improve-ments.Reducing the Cost of Drill and Blast through Blast,Reducing the Cost of Drill and Blast through Blast Design Optimisation,Drilling and Blasting was looked at,adverse effects on the mining process.
