摘要:
In underground uranium mines of China, there are many chamber stopes that can generate and accumulate radon and its daughters, the concentrations of which are about 3-5 times higher than other countries. Therefore, it is very urgent to improve the level of radiation protection of the chamber stopes in China. Ventilation is one of the effective ways to control the concentrations of radon and its daughters. First, this study established the mathematical models that calculated the concentration of radon and its daughters in the chamber stope for designing and optimizing ventilation systems by usi...
