H BLASTING IN SURFACE EXCAVATION

Appropriate blast design is important in order to lessen the production of over size. Secondary blasting can be done by pop shooting (blockholing) and plaster shooting (mudcapping). Shaped charges are sometime used in secondary blasting, but this is much more expensive. Cast Blasting When overburden is removed from a coal or mineral deposit it
