National Company of Lignite Oltenia ( ro, Societatea Naţională a Lignitului Oltenia - SNLO) Târgu Jiu was set up as a commercial society by the Government of Romania in 1997. The main headquarters of the company is placed in Târgu Jiu, Gorj County. The company has its material base in Gorj, Vâlcea and Mehedinți with total reserves of 2 billion tonnes of coal. The annual production is around 35 million tonnes of lignite and 4 million tonnes of anthracite and the total number of employees is around 9,000. Around 85% of the total production comes from Gorj County, especially in the north of the county where coal is extracted near Motru and Rovinari. The main beneficiaries of the coal extracted here are the great Romanian power complexes Rovinari Power Station with a capacity of 1,320 MW, Turceni Power Station with a capacity of 1,650 MW and Craiova Power Station with a capacity of 615 MW thus making Gorj County the biggest power producer in Romania with around 36% of ...

Government-owned Corporation
A state-owned enterprise (SOE) is a government entity which is established or nationalised by the ''national government'' or ''provincial government'' by an executive order or an act of legislation in order to earn profit for the government, control monopoly of the private sector entities, provide products and services to citizens at a lower price and for the achievement of overall financial goals & developmental objectives in a particular country. The national government or provincial government has majority ownership over these ''state owned enterprises''. These ''state owned enterprises'' are also known as public sector undertakings in some countries. Defining characteristics of SOEs are their distinct legal form and possession of financial goals & developmental objectives (e.g., a state railway company may aim to make transportation more accessible and earn profit for the government), SOEs are government entities established to pursue financial objectives and deve ...

Coal
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ...

Lignite
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucket-wheel Excavator
A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns. They rank among the largest vehicles (land or sea) ever produced, and the largest of the bucket-wheel excavators (the 14,200 ton Bagger 293 still holds the Guinness World Record for the heaviest land-based vehicle ever constructed). History Bucket-wheel excavators have been used in mining for the past century, with some of the first being manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spreader (railroad)
A spreader is a type of maintenance equipment designed to spread or shape ballast profiles. The spreader spreads gravel along the railroad ties. The various ploughs, wings and blades of specific spreaders allow them to Snowplow, remove snow, build banks, clean and dig ditches, evenly distribute gravel, as well as trim embankments of brush along the side of the track. Spreaders quickly proved themselves as an extremely economical tool for maintaining trackside drainage ditches and spreading fill dumped beside the track. The operation of the wings was once performed by compressed air, and later hydraulics. Besides the MoW-operation spreaders are also used in open cast mines to clean the tracks from overburden tipped from dump cars. Jordan spreader history The Jordan spreader was the creation of Oswald F. Jordan, a Canadian Roadmaster (rail), road master who worked in the Regional Municipality of Niagara, Niagara, Ontario area on the Canada Southern Railway, later a subsidia ...

Machine
A machine is a physical system using power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and control com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
