A video about the open-cast mining Garzweiler in Germany! It is very amazing! Watch the biggest excavator of the world! 225m long and 96m high!
The Tagebau Garzweiler is a large coal mine using strip mining in Northrhine-Westphalia, Germany. The bucket-wheel excavators used there are the largest vehicles in the world. The whole mine is gradually moving, as the overburden excavated on one end is deposited on the other.
The goal of coal mining is to economically remove coal from the ground. Coal is valued for its energy content, and since the 1880s is 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 States, United Kingdom, and South Africa, a coal mine and its structures are a "colliery". In Australia, "colliery" generally refers to an underground coal mine.
Open Pit Mining
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, or strip) mining methods. Open cast 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. Large Open Cast mines can cover an area of many square kilometers and use very large pieces of equipment. This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and conveyors.
