中文摘要：
矿山开发过程中，尾矿库中的干燥尾砂，在露天堆存状态下会加重大气的环境污染。本文选取霍邱县刘塘坊铁矿尾矿库尾砂样进行了扬尘实验研究，分析了实验风速、含水率与起尘量之间的关系，以及尾砂粒径在排放口与干滩表面的分布变化规律，并提出铁矿尾矿库运行期和闭库期扬尘防治措施。
英文摘要：
The dry tailings left behind by mineral mining could cause more environment pollution under wind action. Dust emission from the LiuTangFang dry tailings of Sinosteel corporation in Huo qiu County was simulated under laboratory conditions. This paper summarizes the relation between rising railings and experimental wind, and dust emission and moisture content. At the same time, the experiment result show that the particle size distribution of the iron tailings was variable from outfall to dry beach. The program is able to give dust control measures in the production phase and closure.
