  • Coal mining - Choosing a mining method Britannica

    Open-pit mining. In open-pit mining of the coal seam, several benches are established in both the overburden strata and the coal seam. The open-pit method is generally practd where thick coal seams are overlain by thick or thin overburden; it is also used for mining steeply pitching coal seams. In the beginning stages of mining, considerable

    Open-cut mining is one method used to extract these minerals from the earth. Open-cut mining is used when the minerals are found over a large area and relatively close to the surface. The open cut mine is dug downwards in benches or steps which slope towards the centre of the pit. To uncover the minerals the land is first cleared of vegetation as when a new building like a house, school

These benches are usually on four to sixty meter intervals, depending on the size of the machinery that is being used. Many quarries do not use benches, as they are usually shallow.

    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
