4 Coal Mining and Processing | Coal: Research

Bituminous coals in the eastern and central United States are mined by both surface and underground mining methods. Anthracite coal is mined exclusively in northeastern Pennsylvania, also by both underground and surface mining methods. Lignite and subbituminous coal production is centered in a small number of large mines (Table 4.3).

The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the most economical surface processes.

Planning Process | Introduction | underground

MINE PLANNING. Planning Process. Once all the exploration information is available, planning can begin in earnest, though often it begins while the exploration process is still in progress. The start of the planning process is the elimination of any parts of the lease which cannot be worked at all or cannot be readily mined for whatever reason. This, together with some knowledge of coal

Retreat mining is the last phase of a common type of coal mining technique referred to as room and pillar mining. Retreat mining is a process that recovers the supporting coal pillars, working from the back of the mine towards the entrance, hence the word retreat.Room and pillar mining advances inward, away from the entrance of the mine.

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.
