Moranbah North Coal Mine
The Moranbah North Coal Mine is a coal mine in the Bowen Basin at Moranbah in Central Queensland, Australia. The mine has coal reserves amounting to 261 million tonnes of coking coal, one of the largest coal reserves in the world. The mine has an annual production capacity of 8 million tonnes of coal. Most of the coal is exported and used to produce iron and steel in Asia but also to India, Brazil and Europe via the Goonyella railway line to Hay Point. The longwall mining operations at the mine began in 1998. Extraction occurs roughly 200 metres below the surface. Operations are expected to continue until around 2033. The mine is owned by Anglo American Australia and several joint partners. Methane gas extracted from the mine powers the Moranbah North Power Station. History In April 2007 underground miner Jason Blee was killed after being pinned to a side wall by a shuttle car. The mine successfully trialed an innovative shotcrete concrete chemical mixture in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moranbah, Queensland
Moranbah is a coal mining town and locality in the Isaac Region, Queensland, Australia. In the , the locality of Moranbah had a population of 8,735 people.

Longwall Mining
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically thick). The longwall panel (the block of coal that is being mined) is typically long (but can be upto long) and wide. History The basic idea of longwall mining was developed in England in the late 17th century. Miners undercut the coal along the width of the coal face, removing coal as it fell, and used wooden props to control the fall of the roof behind the face. This was known as the Shropshire method of mining. While the technology has changed considerably, the basic idea remains the same, to remove essentially all of the coal from a broad coal face and allow the roof and overlying rock to collapse into the void behind, while maintaining a safe working space along the face for the miners. Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" of mining, after the most prominent piec ...

Coal Mines In Queensland
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Mining In Australia
Coal is mined in every state of Australia. The largest black coal resources occur in Queensland and New South Wales. About 70% of coal mined in Australia is exported, mostly to eastern Asia, and of the balance most is used in electricity generation. In 2019-20 Australia exported 390 Mt of coal (177 Mt metallurgical coal and 213 Mt thermal coal) and was the world's largest exporter of metallurgical coal and second largest exporter of thermal coal. Coal mining in Australia has been criticized, due to carbon dioxide emissions during combustion. This criticism is primarily directed at thermal coal, for its connection to coal-fired power stations as a major source of carbon dioxide emissions, and the link to climate change in Australia and worldwide. Coal was responsible for 30% (164 million tonnes) of Australia's greenhouse gas (GHG) emissions, not counting methane and export coal, in 2019. Coal as a fuel was responsible for 41% (160 million tonnes) of carbon dioxide emissions in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shotcrete
Shotcrete, gunite (), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique, first used in 1907 invented by Carl Akeley. It is typically reinforced by conventional steel rods, steel mesh, or fibers. Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions invented by Akeley. In pool construction, however, ''shotcrete'' refers to wet mix and ''gunite'' to dry mix. In this context, these terms are not interchangeable. Shotcrete is placed and compacted/consolidated at the same time, due to the force with which it is ejected from the nozzle. It can be sprayed onto any type or shape of surface, including vertical or overhead areas. Shotcrete has the characteristics of high compressive strength, good durability, water tightness and frost resistance. History Shotcrete, then known as gunite, was invented in 1907 by American taxidermist Carl Akeley to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methane Gas
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other planets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Goonyella Railway Line
The Goonyella railway system is located in Central Queensland, Australia. It services the coal mining area of the Bowen Basin, carrying coal to the Hay Point and Dalrymple Bay Coal Terminals 20 km southeast of Mackay, as well as products to other destinations by way of connections to the North Coast Line at Yukan and the Central Line at Burngrove via the Gregory coal mine branch. It is also connected to the coal loading terminal at Abbot Point (20 km northwest of Bowen) by the GAP line. The line opened on 5 November 1971 and runs for 477 kilometres. A 200 km extension called the Carmichael Rail Network was built in 2021. The Goonyella system is narrow gauge and electrified using 25 kV 50 Hz.
