Rock blasting practices in Malaysian quarry industries ...

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, road work and quarry. Blasting brought a new dimension to engineering excavation work in Malaysia. It is common now to cut wider and better aligned highways through hills instead of having to avoid around it as in the older roads.
