摘要:
Cavern is a place where workers often work in underground spaces, where radon is constantly released from surrounding rock surfaces. It is of great significance to develop effective ventilation to reduce radon in underground space for safe production and occupational health. For the purpose of controlling the radon concentration level in the cavern, the influence of upstream and downstream brattice length, upstream and downstream brattice to wall width on the volume average radon concentration and the plane average radon concentration at the height of the human respiratory zone (Z=1.6m) in the...
