Rock blasting is the controlled use of explosives to excavate or remove rock. It is a technique used most often in mining and civil engineering such as dam construction.
In 1990, 2.1 Tg of commercial explosives was consumed in the USA, representing an estimated expenditure of 3.5 to 4 billion 1993 dollars on blasting. Australia had the highest explosives consumption that year at 500 Tg, and the Scandinavian countries are also big blasters (Persson et al. 1994:1).
