Huge machines called draglines—some the size of an entire city block, able to scoop up to 100 tons in a single load—push rock and dirt into nearby streams and valleys, forever burying waterways. Coal companies use explosives to blast as much as 800 to 1,000 feet off the tops of mountains in order to reach thin coal seams buried deep below.

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 above ground.
