Abstract: Ventilation for reducing radon is one of the main parts of radiation protection in uranium mines. The ventilation technology development of uranium mines in China has been compartmentalized into five periods, based on the ventilation technique advancement and radon exhalation study: the 1958-1965 period, the establishment period of ventilation technology for reducing radon, which mainly reflects in learning and introducing the positive pressure ventilation method in the former Soviet Union; the 1966-1977 reposeful period, reflecting in the application verification and experience accumulation of negative pressure ventilation instead of positive pressure ventilation; the 1978-1989 period is the theory and technique developing period, the theory of interaction between seepage-diffusion law of radon exhalation and tunneling method is proposed, which promotes the development of uranium mine ventilation protection technology; the 1990-2002 is the stagnation period, for the purpose of reducing the input of ventilation protection to reduce production costs, the research on uranium mine ventilation protection technology is at a standstill; and the 2003-2016 is the intensified developing period, using seepage-diffusion law of radon exhalation to guide the research and application of ventilation protection technology under different mining methods. The ventilation technology system for reducing radon of uranium mine in China is coming into being.
