Both on overburden removal at a British Coal open cast site in the 1980s. In 1961 O&K manufactured for the first time in Europe a series of fully hydraulic excavators. They have manufactured over 55.000 hydraulic excavators so far, of which more than 700 are of over 100 tons service weight, also the largest Hydraulic excavator of the world at 900 tons service weight, an engine performance of ...
Strip Mining, Open-pit Mining, Surface Mining, .
Strip mining, like other types of surface mining, finishes in hurting the area around the mine. The rock, gravel, trees, plants, and filth are dumped in regions round the mine. When it rains, this runs over the land and into watercourse and rivers. The rain pushes the mine filth on top of the region topsoil and buries it. The streams lands up being blocked and rivers flood. Water is impure by ...
Mining and Refining – Process
Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. 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 ...

use of heavy machinery, usually bulldozers and dump trucks, is the most common means of removing overburden. Open-pit mining often involves the removal of natively vegetated areas, and is therefore among the most environmentally-destructive types of mining, especially within tropical forests. Because open-pit mining is employed for ore
