The most common purpose of quarries is to extract stone for building materials. Quarries have been used for thousands of years.
Openpit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes.
