    The Mining Process Introduction underground COAL

    Once access has been gained into the coal seam, workings are developed by mining a series of roadways (or "headings"). These roadways are tunnels largely, if not totally, within the seam, usually rectangular in shape though on occasions they may have an arched or even circular profile.

    2018-8-5 · 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. Here removal of overburden and coal extraction proceed in parallel strips along the face of

    2020-12-10 · Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are dynamited and removed to access coal seams.

    2018-3-23 · Miners literally use explosives to blow off the tops of mountains to reveal deposits of ores, which they extract, and then process by usually filtering them through substances such as mercury to purify them somewhat. Mining coal is a lot like mining any other metal or

    Types of Coal Mining FEECO

    When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when
