BLASTING IN SURFACE COAL MINES Blasting overburden and coal in open pit mines is still considered to be an art. Even though much research has been done in areas related to surface mine blast design and anal- ysis, very little of this research seems to have been applied in blasting practice.
However, secondary blasting is the most expensive type of blasting. 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 ...
