What Is Process Of Mining Coal

Coal Mining and Processing. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted. Click to see full answer

    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
