Environment pollution problems in in-situ leaching of uranium and protection measures to be taken

With nuclear power station scale enlarging and the quantity increasing, the requirement for uranium resources assumes an uptrend. Owing to the environment and economy think, the in-situ leach uranium mining is used. Compared with traditional uranium mining methods, although the in-situ leaching uranium method is less pollution to environment, the effect of in-situ leaching on the atmosphere, soil supercrust, surface water, especially groundwater still can not be ignored. On the basis of analyzing the pollution sources, measures to protect the environment are brought forward. (authors)
