No Longer Just a Hole in the Ground The Adaptive Re-Use

A quarry is an area from which rocks such as marble, limestone, and granite are extracted for industrial use. Once depleted of their desired resources, quarries are frequently abandoned. The resulting gaping holes can fill with water and form dangerous quarry lakes while others are turned into unsightly landfills.

What is Quarrying?

Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. So, a quarry is any such working on the surface of the earth where minerals are extracted. Quarries are also known by other names around the world: 'surface mine', ‘pit’, 'open

Code of practice for small quarries Earth Resources

Where a quarry intersects groundwater, the appropriate Rural Water Authority will need to give approval for the collection and pumping of groundwater as part of a quarrying process. Permission must also be obtained from the appropriate RWA should an operator choose to install a groundwater bore for groundwater investigation or extraction purposes.

Quarrying an overview ScienceDirect Topics

Wave quarrying is thought to be the most important erosive process on shore platforms in the storm wave environment of the northern hemisphere (Trenhaile, 1980, 1987). Quarrying is the breaking free and removal of rock fragments by shock pressures from breaking waves, water hammer, and the compression of air in rock joints.

Lime (material) Wikipedia

The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.
