Blasting rock

Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.Drilling and blasting currently utilizes many different varieties of explosive. HistoryThe use of explosives in mining goes back to the year 1627,whenwas first used in place of mechanical tools in the(now ) town of . The innovation spread quickly throughout.
