    The most productive underground method is known as longwall. A block of coal 200 to 300 meters wide and up to 10 kilometers long is defined by a set of tunnels. A cutting machine is then employed to cut the coal which is removed by conveyers. Opencast methods use large equipment to remove the rock above the coal, which can then be mined.
