Colliery
Coal
Coal
mining is the process of extracting coal from the ground. Coal
Coal
is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel
Steel
and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the above-ground structures the pit head. In Australia, "colliery" generally refers to an underground coal mine. In the United States, "colliery" has been used to describe a coal mine operation but nowadays the word is not commonly used. Coal
Coal
mining has had many developments over the recent years, from the early days of men tunnelling, digging and manually extracting the coal on carts, to large open cut and long wall mines

Coalmine (song)
"Coalmine'" is a song written by Roxie Dean, Ron Harbin and Richie McDonald, and recorded by American country music artist Sara Evans. It was released in April 2006 as the third single from her album Real Fine Place.Contents1 Content 2 Chart performance 3 References 4 External linksContent[edit] "Coalmine" is an uptempo fiddle-driven song about a woman who loves her man, a coal miner, and wants him to love her until he returns to work again. Despite Evans coming off two Top 10 hits on the country charts, "Coalmine" met resistance with country radio due to the timing of its release following a deadly explosion at Sago Mine, West Virginia

Excavator
Excavators (hydraulic) are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house".[1] The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels

Open Cut
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 ore 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)

Stratum
In geology and related fields, a stratum (plural: strata) is a layer of sedimentary rock or soil, or igneous rock that were formed at the Earth's surface[1], with internally consistent characteristics that distinguish it from other layers. The "stratum" is the fundamental unit in a stratigraphic column and forms the basis of the study of stratigraphy.Contents1 Characteristics 2 Naming 3 Gallery 4 See also 5 References 6 External linksCharacteristics[edit]The Permian

Bituminous Coal
Bituminous coal
Bituminous coal
or black coal is a relatively soft coal containing a tarlike substance called bitumen or asphalt. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams. These distinctive sequences, which are classified according to either "dull, bright-banded" or "bright, dull-banded", is how bituminous coals are stratigraphically identified. Bituminous coal
Bituminous coal
is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material. Its primary constituents are macerals: vitrinite, and liptinite

Thermal Coal
Coal
Coal
is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal
Coal
is composed primarily of carbon, along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.[1] Coal
Coal
is a fossil fuel that forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. This involves biological and geological processes

Anthracite
Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal except for graphite and is the highest ranking of coal. Anthracite
Anthracite
is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92% and 98%.[1][2] 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.[3] Anthracite
Anthracite
ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite
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

Dragline
A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site. Most crawler cranes, with an added winch drum on the front, can act as a dragline. These units (like other cranes) are designed to be dismantled and transported over the road on flatbed trailers. Draglines used in civil engineering are almost always of this smaller, crane type. These are used for road, port construction, pond and canal dredging, and as pile driving rigs. These types are built by crane manufacturers such as Link-Belt and Hyster. The much larger type which is built on site is commonly used in strip-mining operations to remove overburden above coal and more recently for oil sands mining. The largest heavy draglines are among the largest mobile land machines ever built

Power Shovel
A power shovel (also stripping shovel or front shovel or electric mining shovel or Electric Rope Shovel
Shovel
[2]) is a bucket-equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction.[3] Power Shovels are a type of rope/cable excavator, where the digging arm is controlled and powered by winches and steel ropes, rather than hydraulics like in the more common hydraulic excavators.P&H 4100 XPB cable loading shovel.Contents1 Design 2 Use 3 Operation 4 Gian

Bucket-wheel Excavator
Bucket-wheel excavators (BWEs) are heavy equipment used in surface mining. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations. 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

Mountaintop Removal
Mountaintop removal
Mountaintop removal
mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal
Coal
seams are extracted from a mountain by removing the land, or overburden, above the seams. This method of coal mining is conducted in the Appalachian Mountains
Appalachian Mountains
in the eastern United States. Explosives are used to remove up to 400 vertical feet (120 m) of mountain to expose underlying coal seams. Excess rock and soil is dumped into nearby valleys, in what are called "holler fills" or "valley fills".[1][2][3] Less expensive to execute and requiring fewer employees, mountaintop removal mining began in Appalachia

in the 1970s as an extension of conventional strip mining techniques
