Jan 24, 2020 Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.
Dec 15, 2017 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 ...

Mining amp 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.
