松散破碎射气介质的氡析出能力,对于确定铀矿山地下采场和原地爆破浸出采场降氡通风的需风量和模拟松散破碎射气介质中氡的析出与运移都是一个不可缺少的重要参数。设计了松散破碎射气介质氡浓度的测量装置,建立了其氡析出能力的计算方法,并采用所设计的装置和建立的方法,计算了2种松散破碎射气介质的氡析出能力。

Radon emanation capability of loose fragmented radon-emitting medium is a very important parameter for determining the amount of fresh air for ventilation and radon discharging in the underground stope or stope of in-place leaching of a uranium mine and for simulating the radon emanation and transport in loose fragmented radon-emitting medium.In the paper,an apparatus for measuring radon concentration in the loose fragmented radon-emitting medium is designed and the method for calculating radon emanation capability of the medium is proposed.The apparatus and method are used to calculate the ra...
