Underground exploitation of dimension stones has become an alternative method to traditional open pit exploitation, not only in cases where the underground option is …

The decorative stone quarrying sector has some appreciable differences compared to other mining sectors. The former sector employs different extractive methods (i.e., combined drilling–diamond wire cutting and chain saw cutting with limited use of smooth blasting) than those used in the metallic and industrial minerals extractive sectors.

Locating a potential quarrying site is the first step in the mining process. An outcrop of exposed marble is the surest way for a …

Relation to Mining. IMAR 7 th Edition. Dimension Stone is produced from quarrying. Quarry operations typically involve isolating a mass of stone by cutting it free from the parent mass on all sides but one. The isolated mass is then lifted or separated from the parent mass by breaking it free or by undercutting it with a wire or chain saw.
