Abstract
The mechanism of radon exhalation from surrounding rock fracture has important guiding significance for radon prevention and control in underground research laboratories. The optimal ratio scheme of similar materials in the granite surrounding rock of Beishan underground laboratory was obtained by orthogonal test. The radon exhalation characteristics of fractured rock samples under dry and saturated conditions were obtained by using 10 standard joint roughness coefficient (JRC) curves. The radon exhalation rate of the dry sample and the saturated sample is linearly correlated with the JRC grade, and the radon exhalation rate of the dry sample is 82.65% higher than that of the saturated sample. There was a good correlation between fracture structure parameters (, SF, D0) and radon precipitation in fractured rock mass, which is helpful to reveal the mechanism of radon exhalation fromfractured rock mass.
期刊介绍:
The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
