Quarry – A quarry is a type of open-pit mine from which rock or minerals are extracted. Quarries are generally used for extracting building materials, such as dimension stone, construction aggregate, riprap, sand, and gravel. They are often collocated with concrete and asphalt plants due to the requirement for large amounts of aggregate in those materials. The word quarry can include underground quarrying for stone, such as Bath stone.
Difference between a Quarry and a Mine: –
A.A ‘mine’ can be defined as the extraction site of metals and solid fossil fuels. Mines can be underground or above ground, called a surface mine, ‘open-cast mine’, ‘open-pit’ or just ‘pit’. A ‘quarry’ can be defined as the extraction site of aggregates and industrial minerals above ground.

Another good comparison between a Quarry and a mine;
A quarry is the name for a place where rock is taken from the ground. It is always above ground. A mine can be below ground or at ground level and is where ore is taken from the ground. Marble is quarried, coal is mined.
That is the difference of a mine and a quarry.
