Long Wall Mining is a type of underground mining that involves the extraction of coal from a seam of coal that is located between two walls. The walls are typically constructed from timber, steel, or concrete and are used to support the roof of the mine. The coal is extracted by a machine called a shearer, which is mounted on a long wall face. The shearer is used to cut and remove the coal from the seam. The coal is then transported to the surface for processing.
Long Wall Mining is a common method of coal extraction in many countries, including the United States, Australia, and China. It is a cost-effective and efficient way to extract coal from deep underground seams. The method is also used to extract other minerals such as copper, gold, and uranium.
Some companies in the Long Wall Mining market include BHP Billiton, Rio Tinto, Anglo American, Peabody Energy, and Arch Coal. Show Less Read more
