Rock has been quarried for the construction of buildings and monuments since before recorded history. There is certainly evidence for stone production in ancient times from numerous sites around the world, although it is unclear at which stage formal quarries began to emerge, rather than people just making use of naturally occurring boulders.
Quarrying methods involve extracting stone, sand, or minerals from the earth with techniques such as open-pit mining, where materials like limestone or granite are removed from a surface excavation. Other common methods include drilling, blasting, and cutting, which are often employed to break down and remove large rock masses or precisely cut ...

— Open-pit quarrying is a cost-effective method for extracting large building stone blocks, particularly for stones like granite and limestone, using heavy machinery and explosives. Wire sawing offers precision and reduced environmental impact, making it ideal for high-value stones such as marble and granite while supporting sustainable practices.
An analysis is made of the tools and methods for quarrying limestone and sandstone in ancient Egypt. It is concluded that the chisel, originally of copper and later of bronze or iron, was the principal quarrying tool during all periods, with chisels becoming longer (over 50 cm) at the beginning of the New Kingdom (about 1500 BC).
— Granite is found close to the surface, which means fabricators can cut it from shallower quarries. Large teams with a series of sizable, specialized equipment and …
— Methods of quarrying stone. Methods of quarrying stone: The rocks suitable for the manufacture of stone materials are called useful minerals and operations Known as mining involved in getting minerals. In the mining process, the voids formed are called excavations, and the mining deposits are quarries. The purpose of quarrying is to obtain ...
— Mining - Strip, Open-Pit, Quarrying: It has been estimated that more than two-thirds of the world's yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, …
— Irrespective of the methods of quarrying of stones, this over-burden has to be cleared first before the actual quarrying operation could be started. Similarly, some loosely held rocks on the slopes have to be removed to avoid accidents in the later operations. Methods of Quarrying of Stones. Quarrying methods are classified differently.
— Stone quarrying is generally done at hilly areas where large quantity of stone is available. In fact, stone quarrying is the multistage process by which rock is extracted from the ground. Extracted rock is crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing. Quarrying Methods ...
