摘要
介绍了在地下工程爆破施工的过程中,爆破时所产生的冲击波使岩体介质中的氡及子体析出及扩散的规律。并在此研究的基础上,提出了合理调整地下通风的方案,以控制氡的运移、扩散,确保地下通道、采场及地表环境不受污染。
The regularity of the precipitation and diffusion of radon and radon daughter in rock which because of shock wave produced during explosion in the process of underground project explosion construction is introduced. The proposal of adjust underground ventilation reasonably is raised bases on this research, to control the migration and diffusion of radon, protect the underground passage, stope and surface environment from pollution.
