Uranium: How is it Mined?

Open Pit Mining. Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft).

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
