underground mining methods and equipment for uranium

Uranium mining – what method works best? - Nuclear ...

In the case of underground uranium mines, special precautions (consisting primarily of increased ventilation) are required to protect against airborne radiation exposure. In general, open pit mining is used where deposits are close to the surface and underground mining is used for deep deposits, typically greater than 100 metres deep.

Uranium Mining - NRCan

2021-12-8 · Uranium producers overcome these challenges to mine very high-grade deposits by developing innovative ground freezing techniques and mechanized, "non-entry" underground-mining methods. For lower-grade deposits, more traditional open-pit and underground mining methods are used. Safety is complicated by the presence of radioactive radon gas.
