  • Learn About Wyoming Coal Mining.

    Mining Processing. Coal in Wyoming is uncovered and removed by large machines in a process called surface mining. Before the coal can be removed from the ground, the topsoil and dirt above it is removed using scrapers. This soil is usually removed ahead of the pit and carried behind to place on top of reclaimed areas or backfill.
