摘要:

高寒高纬度地区膏体湿排尾矿库扬尘产生机理及特征、治理技术等相关研究相对较少。针对某高寒高纬度地区大型平地型尾矿库自然条件和扬尘形成原因,提出尾矿库扬尘短期控制方案,利用定向监测方案对实施扬尘抑制策略前后的总悬浮颗粒物浓度进行监测。结果表明:在特定气象条件和操作管理实践下采取的抑尘措施对降低扬尘具有显著效果,同时讨论了中长期抑尘措施,为优化尾矿库的环境管理及高寒高纬度地区膏体湿排尾矿库扬尘治理技术提供了可借鉴的经验。

Abstract:

Research on the mechanism, characteristics, and control technologies of dust generation from pastewet⁃discharge tailings ponds in high⁃cold and high⁃latitude regions is relatively limited. Focusing on the natural conditionsand causes of dust generation in a large flat⁃type tailings dam located in a high⁃cold and high⁃latitude region, ashort⁃term dust control scheme for the tailings dam was proposed. A directional monitoring program was employed tomeasure the concentration of total suspended particulates before and after implementing dust suppression strategies.The results indicate that, under specific meteorological conditions and operational management practices, the adoptedsuppression measures effectively reduced dust emissions. Medium⁃ and long⁃term dust control measures are alsodiscussed, providing valuable experience for optimizing environmental management of tailings dams and for dustsuppression technologies for tailings dams with wet paste discharge in high⁃cold and high⁃latitude areas.
