Throughout the 60+ year history of uranium mining in the U.S., the majority of uranium ore mined has been via conventional open pit or underground methods. The uranium “boom” period of the late 1970’s and early 1980’s witnessed considerable growth of the uranium mining industry in the United States, including development of large open ...

Open pit mining. In open pit mining, overburden is removed by drilling and blasting to expose the ore body, which is then mined by blasting and excavation using loaders and dump trucks. Open pit mines require large holes on the surface, larger than the size of the ore deposit, since the pit’s walls must be sloped to prevent collapse. In 2012 ...

Mining is done by blasting, loading and hauling from the open pit before the uranium-bearing rock is processed to produce uranium oxide. The open pit measures 3.5 km by 1.5 km and is 420m deep. The pit void is mined by a conventional truck-and-shovel operation, with mining being conducted in 15 m benches.
