The big bang: coordinating the world's biggest mine blast

 · It is an essential part of the mining business, for both underground and open pit mining operations. Blasting is typically done by a number of holes being drilled into the rock, which are then filled with explosives. Detonating the explosive causes the rock to collapse. Rubble is then removed and the new tunnel surface is reinforced.

Explosives, Theory Of Breakage And Blasting Operations

 · Theory of Breakage Purpose of blasting • One solid piece → smaller pieces (fragmentation) → to be moved or excavated (movement). • Underground blasting, for example, requires greater fragmentation than surface blasting because of the size of the equipment that can be used and the difficulty of access.
