Quarry
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. The word quarry can also include the underground quarrying for stone, such as Bath stone. Alluvium (from Latin alluvius, from alluere 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Alluvium

A quarry is a place where rocks, sand, or minerals are extracted from the surface of Earth. A quarry is a type of mine called an Alluvium, material deposited by rivers. It is usually most extensively developed in the lower part of the course of a river, forming floodplains and deltas, but may be deposited at any Alluvium Floodplain, Sediment & Soil Britannica

what is a alluvial quarry
alluvial cone A semi-conical type of alluvial fan with very steep slopes; it is higher, narrower, and steeper (e.g., > 40% slopes) than a fan, and composed of coarser, and thicker layers of material deposited by a combination of alluvial episodes and to a much lesser degree, landslides (e.g., debris flow). Coarsest materials. Ver artículoLarge quarry operations that have principal hazards will require PHMPs. 3. There are two new terms to be aware of A-grade quarry operation and A-grade alluvial operation. This is to reflect the differentiated risk management for quarry and alluvial operations determined by the number of workers.
