Embodiment
[0068] Treatment of legacy facilities for uranium mine exploration in high-cold and high-altitude regions (Zoige Plateau region) and vegetation restoration methods, the method includes:
[0069] 1) Cover the land to be treated with soil; determine the thickness of the covering layer according to the radon exhalation rate and the penetrating radiation dose rate, and then cover the land to be treated;
[0070] 2) Carry out slope protection and isolation on the covered treatment area;
[0071] 3) Plant plants on top of the mulch.
[0072] The covering layer is a clay layer with a thickness of 50 cm (the thickness of the clay layer can also be 10-50 cm). can also be like figure 1 Shown is a 20cm (may also be 10-30cm, etc.) thick clay layer 1 and a mixed layer 2 of small particles of regolith and clay with a thickness of 30cm (may also be 20-40cm, etc.) under the clay layer.
[0073] Available Figure 2-Figure 5 As shown, the geocell slope protection isolates the covered treatm...
