摘要
在介绍废石场现状的基础上,针对废石含硫化物的特点,阐述了废石场的治理措施.包括覆土及植被覆盖、废石场边坡稳定化设计与防洪设计等。从覆盖层降氡效果、覆盖层侵蚀防护效果、废石场稳定性、酸性水防治等方面分析了治理效果。分析结果表明对废石场的治理措施是行之有效的,能起到降氡、防治酸性水的作用。
Basic status on waste rock piles of an uranium mine in Jiangxi province before its decom- missioning is introduced. Disposal methods for uranium waste rock piles bearing sulfide are described. The methods involve soil covering, vegetation restoration, reinforcement and flood control measures concerning high slope stabilization in disposal process of waste rock piles. Disposal effects on the validity of covering layers, stability of waste rock piles, and treatment of acidic effluent are analyzed. The results show that the disposal measures on waste rock piles are effective, which can not only cause radon attenuation but also dispose acid water from uranium waste rock bearing sulfide.
