What is OPEN-PIT MINING? What does OPEN-PIT MINING mean? OPEN-PIT MINING meaning - OPEN-PIT MINING definition - OPEN-PIT MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is, where the overburden (surface material covering the valuable deposit) is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for sand, cinder, and gravel). For minerals that occur deep below the surface—where the overburden is thick or the mineral occurs as veins in hard rock—underground mining methods are used to extract the valued material. Open-pit mines that produce building materials and dimension stone are commonly referred to as "quarries." Open-pit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes. However, some form of water control is usually required to keep the mine pit from becoming a lake, if the mine is situated in a climate of considerable precipitation or if any layers of the pit forming the mine border productive aquifers.

How is coal mined? - What is Surface Mining and Underground Mining - Video
 
08:10
How is coal mined? Read Full Story: http://www.spoonfeeding.in/2013/02/how-is-coal-mined-what-is-surface.html Mining is the process of removing coal from the ground. There are two types of mining: underground mining and surface mining. When the coal seam is fewer than 125 feet under the surface, it is mined by surface mining. Coal that is deeper than 125 feet is removed from the ground by underground mining. Underground mining is used when the coal seam lies deep in the earth. In an underground mine only some of the coal is removed. The coal that remains helps support the mine roof. Underground mines look like a system of tunnels. The tunnels are used for traveling throughout the mine, moving coal from place to place and allowing air to circulate in the mine. The coal that is mined is put on conveyor belts. The conveyor belts take the coal to the surface. There are three types of underground mines: slope, drift, and shaft. When the coal seam is close to the surface but too deep to use surface mining, a slope mine can be built. In a slope mine a tunnel slants down from the surface to the coal seam. A drift mine is built when the coal seam lies in the side of a hill or mountain. Drift mines may also be built in a surface mine that has become too deep. There are many drift mines in the eastern United States. The most common type of mine in Illinois is the shaft mine. These mines may be 125 to 1,000 feet deep. A large hole, or shaft, is drilled down into the ground until it reaches the coal seam.

12 Biggest Mines
 
07:39
These huge open-pits in the ground can either be called mines or quarry and they give us amazing things like gold, silver, and copper! Subscribe to Talltanic http://goo.gl/wgfvrr 7. The Barrick Goldstrike Mine Owned and operated by Barrick Gold, which is the largest gold mining company, the goldstrike mine happens to be the largest gold mine in all of North America. Located in Eureka County, Nevada, the goldstrike mine is comprised of 3 different mines, the larger of the three is the Betze-Post open-pit mine, the Meikle, and the Rodeo, both of which are found underground. This complex of mines is also the largest Carlin-type mine in the world. First opened way back in 1986, the mine not only produces gold but silver as well, which just so happens to be where Nevada gets its famous nickname, the “Silver State”, from. 6. The Oyu Tolgoi Mine The name for this combined open-pit mining project translates to Turquoise Hill and is located in the southern region of the Gobi Desert in Mongolia. The mines that are filled with gold-copper ore deposits are actually relatively new and were only recently discovered back in 2001 by the Canadian company Ivanhoe Mines. It’s expected that the mine will reach full capacity in the year 2021. It’s believed that this mine contains around 2,700,000 tons of copper and another 1.7 million ounces of gold. Like with all other mines, the environmental impact that the Oyu Tolgoi mine is often criticized since it is located in such a dry area and uses more than one billion gallons of water each month. 5. The Chuquicamata (choo-kee-kə-mah-tə) Mine In terms of volume, the chuquicamata mine, or the “Chuqui” mine as it’s more commonly known is the second deepest open-pit mine on the planet. This mine can be found in the northern area of Chile where its main export is that of copper. This has been the country’s main export and staple that is crucial to how the people of Chile rely on an income and it’s here that the metal is called “Chile’s salary” ever since they became dependent on the copper industry back when the first World War ended. Copper actually makes up about a third of all the country’s foreign trade but that 33 percent was once at a high percentage of 75% a few years earlier. 4. The Dionysos Marble Quarry This quarry lies on the Penteli Mountain in the town and municipality of Dionysos, Attica in Greece. It’s here that the world famous Dionysos pentelicon marble is extracted. The quarry has been opened for more than a 100 years and it was back in 1949 that it was owned by the Dionysos Marble Company. The quarry currently has 2 underground sites and 9 above ground sites where the marble is extracted. The marble here is protected by law and is solely used for the Acropolis Restoration Project and other ancient buildings in Athens. 3. The Udachnaya Pipe The name of this open-pit mine literally translates to lucky pipe and can be found right outside of the Arctic Circle in Sakha Republic, Russia. This mine was discovered way back in June of 1955 and is believed to contain around 225.8 million carats of diamonds with an estimated 10.4 million carats harvested annually. The diamond mine was taken over by the Russian diamond company Alrosa back in 2010. This is mine also happens to be the third deepest open-pit mine in the world at a depth of 1,970 feet. 2. The Mir Mine Occasionally called the Mirny Mine, this was once a former open-pit diamond mine that is located in Mirny, Eastern Siberia, Russia. This mine reaches a depth of 1,722 feet deep, along with a diameter of 3,900 feet making it one of the largest excavated holes to ever exist. The mine was first discovered back in June of 1955 by a group of three Soviet geologists. It proved to be rather difficult as it seemed like there was always one problem arising after another. The cold winter months provided harsh conditions that slowed production, the mine suffered a flood in the 90’s, and surface operations would cease in June of 2001 with underground operations still moving forward until the whole mine was permanently shut down in 2004. 1. The Bingham Canyon Mine Known by the locals at the Kennecott Copper Mine, the Bingham Canyon Mine is located in the southwest region of Salt Lake City, Utah, in the United States. This massive chasm is known for being the largest man-made excavation in all of the world. Owned by the Rio Tinto Group, the production of this mine was started an astonishing 110-years ago and since then the mine measures at being 2.5 miles long, 0.6 miles deep, and covers a distance of 1,900 acres. The mine endured a tremendous landslide back in 2013 and then a smaller one later that same year.

It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%... Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, and high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. China accounts for the lion's share of production; other producers are Russia, Ukraine, North Korea, Vietnam, the UK, Australia and the US. Total production in 2010 was 670 million tons... Terminology Other terms which refer to anthracite are black coal, hard coal, stone coal (not to be confused with the German Steinkohle or Dutch steenkool which are broader terms meaning all varieties of coal of a stonelike hardness and appearance, like bituminous coal and often anthracite as well, as opposed to lignite, which is softer), blind coal (in Scotland), Kilkenny coal (in Ireland), crow coal (or craw coal from its shiny black appearance), and black diamond. "Blue Coal" is the term for a once-popular and trademarked brand... Anthracite is similar in appearance to the mineraloid jet and is sometimes used as a jet imitation. Anthracite differs from ordinary bituminous coal by its greater hardness, its higher relative density of 1.3--1.4, and lustre, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter... The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 22 to 28 million Btu per short ton (26 to 33 MJ/kg) on a moist, mineral-matter-free basis... Anthracite may be considered to be a transition stage between ordinary bituminous and graphite, produced by the more or less complete elimination of the volatile constituents of the former... History of mining and use In southwest Wales, anthracite has been burned as a domestic fuel since at least medieval times. It was mined near Saundersfoot. In the United States, anthracite coal history began in 1790 in Pottsville, Pennsylvania, with the discovery of coal made by the hunter Necho Allen in what is now known as the Coal Region... By 1795, an anthracite-fired iron furnace had been built on the Schuylkill River... In spring 1808, John and Abijah Smith shipped the first commercially mined load of anthracite down the Susquehanna River from Plymouth, Pennsylvania, marking the birth of commercial anthracite mining in the United States. From that first mine, production rose to an all-time high of over 100 million tons in 1917. From the late 19th century until the 1950s, anthracite was the most popular fuel for heating homes and other buildings in the northern United States... Many large public buildings, such as schools, were heated with anthracite-burning furnaces through the 1980s... http://en.wikipedia.org/wiki/Coal_mining The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a colliery... Coal mining has had a lot of developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyor, jacks and shearers...

By 1795, an anthracite-fired iron furnace had been built on the Schuylkill River... In spring 1808, John and Abijah Smith shipped the first commercially mined load of anthracite down the Susquehanna River from Plymouth, Pennsylvania, marking the birth of commercial anthracite mining in the United States. From that first mine, production rose to an all-time high of over 100 million tons in 1917. From the late 19th century until the 1950s, anthracite was the most popular fuel for heating homes and other buildings in the northern United States... Many large public buildings, such as schools, were heated with anthracite-burning furnaces through the 1980s... http://en.wikipedia.org/wiki/Coal_mining The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a colliery... Coal mining has had a lot of developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyor, jacks and shearers...

Hazards Around Bins And Hoppers 1978 Mine Safety & Health Administration

Encourages workers to follow the safe and correct operating procedures that apply to their jobs."

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ https://en.wikipedia.org/wiki/Mining#Safety Safety has long been a concern in the mining business especially in sub-surface mining. The Courrières mine disaster, Europe's worst mining accident, involved the death of 1,099 miners in Northern France on March 10, 1906. This disaster was surpassed only by the Benxihu Colliery accident in China on April 26, 1942, which killed 1,549 miners. While mining today is substantially safer than it was in previous decades, mining accidents still occur. Government figures indicate that 5,000 Chinese miners die in accidents each year, while other reports have suggested a figure as high as 20,000. Mining accidents continue worldwide, including accidents causing dozens of fatalities at a time such as the 2007 Ulyanovskaya Mine disaster in Russia, the 2009 Heilongjiang mine explosion in China, and the 2010 Upper Big Branch Mine disaster in the United States. Mining ventilation is a significant safety concern for many miners. Poor ventilation inside sub-surface mines causes exposure to harmful gases, heat, and dust, which can cause illness, injury, and death. The concentration of methane and other airborne contaminants underground can generally be controlled by dilution (ventilation), capture before entering the host air stream (methane drainage), or isolation (seals and stoppings). Rock dusts, including coal dust and silicon dust, can cause long-term lung problems including silicosis, asbestosis, and pneumoconiosis (also known as miners lung or black lung disease). A ventilation system is set up to force a stream of air through the working areas of the mine. The air circulation necessary for effective ventilation of a mine is generated by one or more large mine fans, usually located above ground. Air flows in one direction only, making circuits through the mine such that each main work area constantly receives a supply of fresh air. Watering down in coal mines also helps to keep dust levels down: by spraying the machine with water and filtering the dust-laden water with a scrubber fan, miners can successfully trap the dust. Gases in mines can poison the workers or displace the oxygen in the mine, causing asphyxiation... Ignited methane gas is a common source of explosions in coal mines... Miners utilize equipment strong enough to break through extremely hard layers of the Earth's crust. This equipment, combined with the closed work space in which underground miners work, can cause hearing loss... Since mining entails removing dirt and rock from its natural location, thereby creating large empty pits, rooms, and tunnels, cave-ins as well as ground and rock falls are a major concern within mines. Modern techniques for timbering and bracing walls and ceilings within sub-surface mines have reduced the number of fatalities due to cave-ins, but ground falls continue to represent up to 50% of mining fatalities. Even in cases where mine collapses are not instantly fatal, they can trap mine workers deep underground. Cases such as these often lead to high-profile rescue efforts, such as when 33 Chilean miners were trapped deep underground for 69 days in 2010. High temperatures and humidity may result in heat-related illnesses, including heat stroke, which can be fatal. The presence of heavy equipment in confined spaces also poses a risk to miners. To improve the safety of mine workers, modern mines use automation and remote operation including, for example, such equipment as automated loaders and remotely operated rockbreakers. However, despite modern improvements to safety practices, mining remains a dangerous occupation throughout the world...

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Anthracite Anthracite... is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, and high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. China accounts for the majority of global production; other producers are Russia, Ukraine, North Korea, Vietnam, the UK, Australia and the US. Total production in 2010 was 670 million tons... Other terms which refer to anthracite are black coal, hard coal, stone coal... blind coal... Kilkenny coal... crow coal... and black diamond. In the United States, anthracite coal history began in 1790 in Pottsville, Pennsylvania, with the discovery of coal made by the hunter Necho Allen in what is now known as the Coal Region. Legend has it that Allen fell asleep at the base of Broad Mountain and woke to the sight of a large fire because his campfire had ignited an outcropping of anthracite coal. By 1795, an anthracite-fired iron furnace had been built on the Schuylkill River. Anthracite was first experimentally burned as a residential heating fuel in the US on 11 February 1808, by Judge Jesse Fell in Wilkes-Barre, Pennsylvania, on an open grate in a fireplace. Anthracite differs from wood in that it needs a draft from the bottom, and Judge Fell proved with his grate design that it was a viable heating fuel. In spring 1808, John and Abijah Smith shipped the first commercially mined load of anthracite down the Susquehanna River from Plymouth, Pennsylvania, marking the birth of commercial anthracite mining in the United States. From that first mine, production rose to an all-time high of over 100 million tons in 1917... From the late 19th century until the 1950s, anthracite was the most popular fuel for heating homes and other buildings in the northern United States, until it was supplanted first by oil burning systems and more recently by natural gas systems... China today mines by far the largest share of global anthracite production, accounting for more than three-quarters of global output. Most Chinese production is of standard-grade anthracite, which is used in power generation. Increased demand in China has made that country into a net importer of the fuel, mostly from Vietnam, another major producer of anthracite for power generation, although increasing domestic consumption in Vietnam means that exports may be scaled back. Current U.S. anthracite production averages around 5 million tons per year. Of that, about 1.8 million tons were mined in the state of Pennsylvania...

The Real Cost of Open Cast Mining in South Wales
 
03:57
Proposals for an open cast mine at Nant Llesg, Rhymney will soon be submitted by Scottish developer Miller Argent. This will be a huge surface mine that would remain in operation for 17 years and excavate around 6m tonnes of coal from an area of around 3,000 acres - its eastern edge being just 500m from the town of Rhymney. Green Valleys Alliance is a consortium of local businesses with backing from the local community that launched its opposition to the proposals in July. The Alliance is concerned that the mine will have a negative impact on local jobs and investment in the area, be detrimental to the environment and people's quality of life and could make the local population vulnerable to long term health risks. Local businessman Mitchell Field, who employs 140 people at Rhymney-based cosmetics business Richards & Appleby Ltd and features in the video, said: "We have decided to release this video to highlight the negative impact that these proposals will have on the local area and show people exactly why our group is opposed to the creation of this mine." "The video shows the areas that will be affected - lush green fields and farm land that will be completely destroyed - and highlights our concerns about the real risk of job losses and economic decline in the area if this mine goes ahead."

How a Canadian company will mine the sea bed near Papua New Guinea
 
01:12
Canadian mining company Nautilus Minerals has reached an agreement with the government of Papua New Guinea to begin mining an area of seabed believed to be rich in gold and copper ores, according to the BBC. Under the terms of the agreement, Papua New Guinea will contribute $120 million to the operation and receive a 15 percent share in the mine. Environmentalists say the mine will devastate the area and cause long-lasting damage to the environment. The BBC reports that "the mine will target an area of hydrothermal vents where superheated, highly acidic water emerges from the seabed, where it encounters far colder and more alkaline seawater, forcing it to deposit high concentrations of minerals." The report continues: The result is that the seabed is formed of ores that are far richer in gold and copper than ores found on land. Mike Johnston, chief executive of Nautilus Minerals told the BBC "that a temperature probe left in place for 18 months was found to have 'high grade copper all over it'." Nautilus announced in April that it had completed its bulk cutter, the first component of its Seafloor Production Tools system, which will be used to mine the seabed. Nautilus also approximately 500,000 square kilometres of "highly prospective exploration acreage" in Papua New Guinea, the Solomon Islands, Fiji, Vanuatu and Tonga, as well as in international waters in the eastern Pacific, the company said in a press release. ----------------------------------------­­---------------------------------------­-­---------------- Next Animation Studio’s News Direct service provides daily, high-quality, informative 3D news animations that fill in for missing footage and help viewers understand breaking news stories or in-depth features on science, technology, and health.

Developing a skilled workforce at our Raglan Mine in Canada
 
02:14
Raglan Mine is a Glencore nickel operation in northern Canada. In 2008, Raglan Mine implemented the Tamatumani program intended to attract and retain the largest possible number of Inuit employees. Tamatumani aims to encourage more long-term employment, expand Inuit mining opportunities and foster better workplace integration. One of the Tamatumani initiatives is the “Stope School,” a program that trains Inuit employees in mining-related tasks. Over a two year period, trainees become apprentice miners and receive training in an underground environment. Once the program is completed, trainees become full miners. More than 25 Inuit trainees have graduated from the Stope School since 2008. So far, Tamatumani has placed Inuit workers in over 120 positions, covering more than 45 different types of jobs. The number of Inuit employees has risen from 55 in 1998 to 182 in June 2016, the highest number in Raglan Mine’s history. In June 2016, over 20% of our workforce at the Raglan Mine site was Inuit.
