  • 4 Coal Mining and Processing Coal: Research and

    The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2

  • 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.
