  • How Coal Works | Union of Concerned Scientists

     · Two dominant methods account for the vast majority of underground coal mining: "room and pillar" and "longwall" mining.. In room and pillar mining, seams of coal are partially mined, leaving large pillars of coal intact to support the overlying layers of rock. When finished, miners practice "retreat" mining, extracting as much coal as possible from the remaining pillars as they ...

    In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

  • Coal mining and transportation

     · Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth''s surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation''s coal reserves and to produce about three times more coal in one hour than in 1978.

  • Coal mining

    Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity.
