CONTINUOUS COAL QALITY CONTROL IN OPENCAST MINING
opencast mines, the masses are exclusively transported by belt conveyors. The heating value of the lignite ranges between 7,100 and 10,500 kJ/kg and its moisture content between 50 and 60 %. The ash content of lignite amounts to about 2 %. In the run-of-mine lignite, this content can rise to

Open-pit mining - Wikipedia
Open-pit mining, also known as mega-mining, 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-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

Coal mining - Wikipedia
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited

Reclamation of Degraded Landscapes due to Opencast
01-07-2013 All mining operations, due to their nature, have negative impacts on the cultural landscape. And opencast mining activities are not an exception, as they drastically change the former dynamic equilibrium of the landscape, leading to the formation of new ecosystems. Only the vegetation establishment by itself is not a proper approach.
