What is Open Cut Mining? | Bravus Mining & Resources
Open-cut mining is a process of resource extraction where it is dug up from the surface. Also known as open-pit mining or open-cast mining, it is the most common form of extraction for minerals or coal in Australia. The technique of open-cut mining is used when the deposits are close enough to the surface to be readily extracted.
