    Coal Mining and Processing Energy Trends Insider

    Many U.S. coal beds are very near the ground’s surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978.
