  • Coal mining in Kentucky Wikipedia

    Coal was discovered in Kentucky in 1750. Since the first commercial coal mine opened in 1820 coal has gained both economic importance and controversy regarding its environmental consequences. As of 2010 there were 442 operating coal mines in the state, and as of 2017 there are less than 4,000 underground coalminers.

Coal miners remove the soil above the coal. The coal can then be removed without the coal miners having to go deep underground.Underground mining is when the coal is farther underground, making it too expensive to remove soil. In this process, coal miners and all of the coal mining equipment are brought deep underground and coal is carried up out of the ground.Coal mining has had many developments over the recent years, from the early...
