摘要
介绍了在地下开采中氡及子体在介质中渗流的必要条件:氡源、通道、压力梯度,氡在介质中的渗流规律,提出了通过合理调整地下通风网络,控制氡的扩散、渗流,确保矿井中及地表环境不受污染。
This paper describes the essential conditions for radon and radon daughters to permeate in the medium in the process of underground mining, including radon source, path, pressure gradient and the flow pattern of radon in the medium. It puts forward that the rational regulation of underground ventilation network and the control of radon emanation and diffusion can protect underground mine and surface from radon pollution.
