4.1 Before the operation of paving, mining and processing and smelting facilities, each stage of the entire process (exploration, mining, processing and decommissioning) must be analyzed , evaluate the waste generated by each process and its radioactive contamination impact. 4.2·During the mining and treatment period of the chain and du mines. Measures must be taken to minimize the amount of waste generated and to control the release of radioactive materials from liquid and gaseous effluents into the environment. It is necessary to ensure that the virtual objects are under appropriate control, and the spillage of waste rock and tailing mines is strictly prohibited; to control the release of oxygen and radioactive dust into the atmosphere: to control the contamination of surface water and groundwater by radionuclides and other radionuclides, and to control the Solid waste is polluted by overflowing and pollutes surface water and groundwater. 4. 3. After the operation is stopped, during the decommissioning period and after, the management and control of trapped waste must be maintained, the radioactive hazards of waste rock and tailings must be controlled, and the oxygen and protons released by waste rock and mines must be controlled. The diffusion of radionuclides in the atmosphere prevents radionuclides and other radionuclides from entering surface water and groundwater through any possible means.
4.4 Radioactive wastes from mining and metallurgy contain long-lived radionuclides. Its release to the environment from final disposal tailings ponds and waste rock sites must be controlled, and various long-term natural processes (such as weathering, water overflow, changes in river flow direction, earthquakes, etc.), as well as human activities (such as engaging in construction or agricultural production, etc.) on the tailings ponds and waste rock dumps after final disposal, and this effect should be eliminated or minimized as much as possible. Auxiliary radiation protection quality principles and general basic requirements
5.1 In the practice of radioactive material management in tongs, needle mining and metallurgy, the relevant radiation protection principles of GB 8703 must be followed, that is, the legitimacy of practice, optimization of radiation protection and personal dosing Limits.
5.2 When considering the long-term impact of the amount of radioactive materials disposed of in mining and metallurgy, requirements should be made for the dose levels that individuals may be exposed to in the future. 5.3 Due to the tailings pond and radioactive waste after final disposal The field will be damaged by natural processes and human activities, and the impact of such probabilistic events on the sound field should be considered

6 Design of waste storage facilities
GB. 14585-93
6. 1 It must be ensured that the design of radioactive waste management facilities in towns and mines meets the requirements of this standard and other requirements specified by the relevant competent authorities, as well as the dose equivalent limits specified in GB 8703 for corresponding situations. Value requirements. 6. 2 Correct design must include:
