Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally coal seam thickness and geology are factors in selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the long wall, which is a shear blade that runs along sections of the coal seam. Many coals extracted from both surface and underground mines requir…

In 1912, for example, the Hoadley Knight Machine was developed for mining coal. Primitive by modern standards, it used an electric motor, hydraulic swings and water sprays to breakdown rock faces. Since the early 1900s there have been great advancements in continuous mining vehicles, but most still consist of rotating steel drums with tungsten teeth which dislodge chunks of coal.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

In this situation continuous mining machines are used in the "room-and-pillar" method. In the 1950s, a new underground mining method appeared in Europe. It is called a 'longwall mining' method that applies laser technology. Today, it is widely used by coal mining companies in the world.
