  • Outline of mining Wikipedia

    The following outline is provided as an overview of and topical guide to mining: . Mining extraction of valuable minerals or other geological materials from the earth, usually (but not always) from an ore body, vein or (coal) seam. Any material that cannot be grown from agricultural processes, or created artificially in a laboratory or factory, is usually mined.

  • Coal National Geographic Society

    Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

  • List of Mining Equipment Career Trend

    Coalminers use electric-powered shuttle cars to transport coal from the coal bed to safer points in the mine. From there, miners can use standard scoops, or haulage vehicles, to drive their loads completely out of the mine. Miners of all types use haulage vehicles for various tasks.
