Quarrying refers to the process of extracting natural stone, sand, and quarry aggregates from the earth for use in construction projects. Unlike mining, which focuses on extracting minerals or metals, quarrying is dedicated to the extraction of non-metallic materials used in construction, such as limestone, sandstone, granite, and gravel.

The Quarrying Process. The process of quarrying involves several stages, each of which requires a different set of skills and equipment. The first stage is the identification of a suitable quarry site. This involves geological surveys to determine the quality and quantity of the stone available at the site.

The quarrying process consists of separating large blocks, sometimes called loafs, from the surrounding rock. These blocks may be 6 metres high by 6 metres deep and 12 to 18 metres (about 40 to 60 feet) long, and they may weigh in the range of 1,200 to 2,000 tons.

Once the overburden has been removed by processes similar to those used in hard rock quarrying, deposits of sand and gravel are usually extracted by a range of earth-moving plant (Figure 16.6).Some sand and gravel pits extract beneath the local water table and are 'wet pits', whereas others exploit wholly above the water and are 'dry pits'.

2. Quarrying of Stones. Definition: Stones occur in the form of natural rock masses or layers on the surface. The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves …

Quarrying is the heavy industrial process of extracting minerals and natural resources like rocks, sand, and gravel from the surface of the earth. Also known as aggregates, quarried materials are heavily used in the building and construction industries in the construction of houses, roads, hospitals, school and other structures. ...

On wave-cut platforms and at cliff bases, quarrying is the major process of erosion, being the prime mechanism of removing blocks lying below the level of saturation. Both Jutson (1954) and Hills (1949) reported channels cut into platforms by wave quarrying, often along lines of weakness, particularly on more exposed sections.

Stone quarrying is the process of extracting stones from natural rock surfaces for various engineering and construction purposes. Unlike mining, which is an underground activity, quarrying is performed on exposed rock surfaces. Stones obtained from quarrying are used in building structures, paving roads, and other infrastructure projects. Quarrying generally occurs …
