'To obliterate a mountain, one must first drill a series of holes 2.4 metres deep – in either a square or diagonal pattern, depending on the rock type and face condition. A crew moves in to load the holes with blasting agent, typically a mix of ammonium nitrate and fuel oil. Detonators and boosters are laid and an explosive cord is run over the mountain face. A fuse is lit. It explodes the detonator, which explodes the cord, which explodes the boosters, which explodes the blast mix, which in turn explodes the mountain.' (Introduction)
