Stone Quarrying: Definition, Sites, Considerations and

Important Considerations 4. Methods. Definition of Quarrying: The process of taking out stones from natural rock beds is known as the quarrying. The term quarry is used to indicate the exposed surface of natural rocks. The stones, thus obtained, are used for various engineering purposes. The difference between a mine and a quarry should be noted.
