Gravel Pit
A gravel pit is an open-pit mine for the extraction of gravel. Gravel pits often lie in river valleys where the water table is high, so they may naturally fill with water to form ponds or lakes. Old, abandoned gravel pits are normally used either as nature reserves, or as amenity areas for water sports, landfills and walking. In Germany former gravel or sand pits that have filled up with water are known as ''Baggersee'' ("power dug lake") and popular for recreational use. In addition, many gravel pits in the United Kingdom have been stocked with freshwater fish such as the common carp to create coarse fishing locations. Gravel and sand are mined for concrete, construction aggregate and other industrial mineral uses.

Wu Tang Clan
Wu-Tang Clan is an American hip hop group formed in Staten Island, New York City, in 1992. Its original members include RZA, GZA, Ol' Dirty Bastard, Method Man, Raekwon, Ghostface Killah, Inspectah Deck, U-God, and Masta Killa. Close affiliate Cappadonna later became an official member. Wu-Tang Clan are regarded as a highly influential group in hip hop, helping to popularize and develop the East Coast hip hop and hardcore hip hop styles. After signing to Steve Rifkind's label Loud Records in 1992, Wu-Tang Clan released their debut album '' Enter the Wu-Tang (36 Chambers)'' in 1993; initially receiving positive reviews, it has since garnered widespread critical acclaim and is widely considered to be one of the greatest hip hop albums of all time. Members of the group released solo albums between 1994 and 1996. In 1997, the group released their second album, '' Wu-Tang Forever''. It debuted atop the ''Billboard'' 200 and was nominated for Best Rap Album at the 1998 Grammy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction Aggregate
Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost exte ...

Stone Industry
Stone industry refers to the part of the primary sector of the economy, similar to the mining industry, but concerned with excavations of stones, in particular granite, marble, slate and sandstone. Other products of the industry include crushed stone and dimension stone. Stone industry is one of the oldest in the world. Creation of stone tools (microliths industry) in the region of South Africa has been dated to about 60,000–70,000 years ago. Granite and marble mining existing as far back as ancient Egypt. Crushed stone was used extensively by the first great road building civilizations, such as ancient Greece and ancient Rome.

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is ...

Rock (geology)
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of exi ...

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 reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk * China clay * Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble * Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operations w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay Pit
A clay pit is a quarry or mine for the extraction of clay, which is generally used for manufacturing pottery, bricks or Portland cement. Quarries where clay is mined to make bricks are sometimes called brick pits. A brickyard or brickworks is often located alongside a clay pit to reduce the transport costs of the raw material. Today, pottery producers are often not sited near the source of their clay and usually do not own the clay deposits. In these industries, the other essential raw material is fuel for firing and potteries may be located near to fuel sources. Former claypits are sometimes filled with water and used for recreational purposes such as sailing and scuba diving. The Eden Project at Bodelva near St Austell, Cornwall, UK is a major redevelopment of a former china clay (kaolin) pit for educational and environmental purposes.

Borrow Pit
Digging, also referred to as excavation, is the process of using some implement such as claws, hands, manual tools or heavy equipment, to remove material from a solid surface, usually soil, sand or rock on the surface of Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the second being the removal and relocation of the material found there.Carl Dreher,The Right Way to Dig, ''Popular Science'' (March 1957), p. 179. In a simple digging situation, this may be accomplished in a single motion, with the digging implement being used to break the surface and immediately fling the material away from the hole or other structure being dug. Many kinds of animals engage in digging, either as part of burrowing behavior or to search for food or water under the surface of the ground.Zen Faulkes,Morphological Adaptations for Digging and Burrowing (2013), p. 276-295. Historically, humans have engaged in digging for both of thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
