Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
Most open cast mines in the United States extract bituminous coal. In Canada (BC), Australia and South Africa, open cast mining is used for both thermal and metallurgical coals. In New South Wales open casting for steam coal and anthracite is practiced. Surface mining accounts for around 80 percent of production in Australia, while in the US it ...

Coal mining is the process of extracting 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 Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine – a pit, and the ...

The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.
Open-pit coal mining in the United Kingdom is in decline. Output has fallen every year since 2010. In 2010, the United Kingdom was forecast to produce about ten million tonnes (9,800,000 long tons; 11,000,000 short tons) of coal a year from open-pit mines.Most came from Scotland, with the largest operator there being the Scottish Coal subsidiary of Scottish Resources Group.

Mining: Barite mining in Missouri began around 1850; however, early lead mining operations began as early as 1725 in the same area, but barite was cast aside as a waste product at that time. Barite production data has been recorded from 1872 to present. The Washington County deposit is the major source of Missouri's barite production.
