A quarry is typically defined as being a surface excavation for the production of rock as the principal product. As such, it differs from an open cast, open-cut, surface or open-pit mine in that the rock itself is the valuable commodity, rather than a specific mineral within the rock mass. Quarrying is used mainly in the production of ...

Forming the Bench. Mining marble blocks from the wall of the quarry starts with a "bench wall." The bench wall is a large section of marble along a vertical wall that is cut with diamond cables, drills, and torches. Dynamite loosens the bench wall from the side of the quarry, and the separated wall can then be processed and cut into individual ...
