how to mine and process coal
Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it
