A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground.
The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact.
Quarries in level areas with shallow groundwater or which are located close to surface water often have engineering problems with drainage.
Generally the water is removed by pumping while the quarry is operational, but for high inflows more complex approaches may be required.
Many people and municipalities consider quarries to be eyesores and require various abatement methods to address problems with noise, dust, and appearance.
One of the more effective and famous examples of successful quarry restoration is Butchart Gardens in Victoria, British Columbia, Canada.
