Experimental study on dam damage and radon precipitation in uranium tailing ponds based on impact loading effects

The horizontal impact experiments were carried out by using the scale down model of uranium tailing pond dams to analyze the trend of radon precipitation rate after the destruction of uranium tailing pond dams and the persistence of radon precipitation rate in time series judged by R/S fractal fractal method. The results show that with the gradual increase of impact velocity and penetration depth of impactor, the average accumulated radon concentration in the post-impact uranium tailings pond dam model gradually increases compared with the background accumulated radon concentration in the pre-impact uranium tailings pond dam model.
