Gravel extraction is the process of removing gravel from the ground for use in construction and other applications. This material is often found in riverbeds, lakes, and quarries. It is essential for making concrete, asphalt, and road bases, contributing to infrastructure development. The extraction process typically involves digging or dredging to collect the gravel. After extraction, the gravel is usually washed and sorted by size before being transported to construction sites. Proper management and regulation are important to minimize environmental impacts, such as habitat destruction and water pollution, associated with gravel mining.
