Coal mining is the process of extracting coal from the ground or from a mine. 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 Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a "pit", and above-ground mining structures are referred to as a "pit head". In Australia, "colliery" generally refers to an underground coal mine.
This is a timeline of environmental history of New Zealand. It includes notable events affecting the natural environment of New Zealand as a result of human activity.
The Resource Management Act (RMA) passed in 1991 in New Zealand is a significant, and at times, controversial Act of Parliament. The RMA promotes the sustainable management of natural and physical resources such as land, air and water. New Zealand's Ministry for the Environment describes the RMA as New Zealand's principal legislation for environmental management.
The Save Happy Valley Coalition (SHVC) is an environmental activist movement formed with the express purpose of preventing the Cypress mine, an open cast coal mine on the West Coast of New Zealand, from proceeding.
Solid Energy was the largest coal mining company in New Zealand and is a state owned enterprise of the New Zealand Government.
Powelliphanta augusta or the Mount Augustus snail, previously provisionally known as Powelliphanta "Augustus", is a species of large, carnivorous land snail, a terrestrial pulmonate gastropod mollusc in the family Rhytididae. Naturally occurring only on Mount Augustus near Westport on New Zealand's South Island, their entire habitat was destroyed by coal mining. The world population was taken into captivity, in theory until their habitat was restored and they could be released. The mining company concerned went bankrupt and habitat restoration has been unsuccessful, so the species' future is uncertain.
The Cypress Mine is an extension to the open-cast coal mine the Stockton Mine’s operational area, to the east into the Upper Waimangaroa Mining Permit area, on the West Coast of New Zealand. The mine commenced operation in 2014.
The Mokihinui Hydro was a proposed hydroelectric dam and power station planned for conservation land on the Mōkihinui River on the West Coast of New Zealand. The project by Meridian Energy was expected to cost $300 million.
Mining in New Zealand began when the Māori quarried rock such as argillite in times prior to European colonisation. Mining by Europeans began in the latter half of the 19th century.
The Ngakawau Restoration Project is a proposed hydro scheme planned to divert acid mine drainage from coal mines to an ocean outfall to restore water quality of the Ngākawau River, in the northern section of the West Coast of the South Island of New Zealand. The project is a configuration of the Stockton Plateau Hydro Scheme being developed by Hydro Developments (2013) Limited. Project information can be found at https://hydrodevelopments.co.nz
Stockton Mine, on the Stockton Coal Field, is New Zealand's largest opencast mining operation. The entrance to the mine is at the former settlement of Stockton.
÷Some of the more notable coal companies in Australia are the following:
Denniston Plateau is an 18 km long, 600–800 m high coalfield plateau in the Papahaua Range on the West Coast of the South Island of New Zealand. A combination of impermeable rock, high rainfall, and shallow acidic soil has created a unique ecosystem of stunted trees and heath-like vegetation which is home to numerous endemic and undescribed species of plants and invertebrates. The plateau contains rich seams of high-quality coal, which led to the creation and abandonment of the mining towns of Denniston and Millerton, and the current Stockton Mine. Plans to create a new open-cast mine on the southern part of the plateau have become an environmental controversy.
The Escarpment Mine Project is an opencast coal mine at the Mount Rochfort Conservation Area on the Denniston Plateau on the West Coast of New Zealand in the vicinity of the disused Escarpment Mine. Bathurst Resources Limited intended to extract and export between one and four million tonnes of coal a year from open cast mining in an area of 200 hectares of conservation land on the southern Denniston Plateau. The mine would be the second largest opencast coal mine in New Zealand after Solid Energy's Stockton Mine on the Stockton Plateau. Environmental groups such as Forest and Bird and the West Coast Environment Network opposed the project.
The Rockies Incline was an inclined tramway on the West Coast of the South Island of New Zealand that for ten years from 1925 to 1935 brought coal from the Westport Main Coal Company’s mine on the Millerton-Stockton plateau down to the Westport to Seddonville railway line near sea level.
Satgram Area is one of the 14 operational areas of Eastern Coalfields Limited located mainly in Asansol subdivision of Paschim Bardhaman district and partly in Bankura Sadar subdivision in Bankura district, both in the state of West Bengal, India.
Salanpur Area is one of the 14 operational areas of Eastern Coalfields Limited located in Asansol subdivision of Paschim Bardhaman district, in the state of West Bengal, India.
Kenda Area is one of the 14 operational areas of Eastern Coalfields Limited located mostly in Durgapur subdivision and partly in Asansol subdivision of Paschim Bardhaman district in the state of West Bengal, India.
Bathurst Resources, along with a number of subsidiaries, is a coal mining company in New Zealand that was established in 2010.
The Barrytown Flats are a 17 km (11 mi) coastal plain north of Greymouth on the West Coast of New Zealand's South Island. A series of postglacial shorelines and dunes backed by a former sea cliff, they was originally covered with wetland and lowland forest, including numerous nīkau palms. The sands were extensively sluiced and dredged for gold from the 1860s, centred on the small settlement of Barrytown. The drier areas of the flats have been converted into pasture, but significant areas of forest remain, including Nikau Scenic Reserve. The flats are bordered by Paparoa National Park and the only breeding site of the Westland petrel. There are significant deposits of ilmenite in the Barrytown sands, and there have been several mining proposals, but the possible environmental consequences have been contentious.
