Underground aggregate mining in Athens: a promising ...

01.10.2001· Underground aggregate mining in Attica could prove to be a reliable alternative for the supply of aggregate materials, considering the difficulties that open-pit quarries have to confront. Besides, the creation of an underground space in Attica could be of a major significance, as the existence of storage areas is inadequate and leases are extremely high. The output of the analysis presented in this paper showed that the development of underground …
