3. The Environmental Impacts of Aggregate Extraction

Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal wildlife, it also leads to a huge loss of biodiversity as plants and aquatic habitats are destroyed.

Quarrying of Stones: Its Methods, Selection of Site

The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at considerable depth.

What is quarrying and why is it important?

Quarrying is part of the wider extractive industry and the natural stone, gravel and sand that comes from a quarry are known as 'aggregate'. It's fair to say that people don't give much thought to the subject of aggregates, and may only know a quarry as a hole in the ground.
