Quarry - Wikipedia

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 are regulated in some jurisdictions to reduce their environmental impacts. The word quarry can also include the underground quarrying for stone, such as Bath stoneFree Environmental PowerPoint Templates, Themes and PPTDownload Free Environmental PowerPoint Templates and Themes. You can use these Environmental PPT in Your Projects and presentations.Mining and Water Pollution — Safe Drinking Water FoundationAfter being removed, waste rock, which often contains acid-generating sulphides, heavy metals, and other contaminants, is usually stored above ground in large free-draining piles. This waste rock and the exposed bedrock walls from which it is excavated are the source of most of the metals pollution caused by mining in British Columbia.
