寒旱区铀矿露天开采防尘抑尘措施分析

Analysis of dust prevention and suppression in open-pit mining for uranium mine in cold and arid areas

铀矿露天开采属开放式作业环境,产尘环节众多,粉尘污染严重,防治难度较大。为了减缓铀矿露天开采对区域大气环境造成的不利影响,通过对位于北方地区的某铀矿床规划开采方案与产尘环节进行分析,结合地区环境气候特征总结,提出了适用的防尘抑尘技术措施,为北方地区铀矿露天开采的粉尘污染防治提供技术借鉴。

Open-pit mining of uranium mine is an open working environment,there are many dust producing links,and dust pollution is serious,so it's difficult to prevent and control.In order to mitigate the adverse impact of uranium open-pit mining on the regional atmospheric environment,the planned mining scheme and dust production links of a uranium deposit in the northern region were analysed,combined with summary of regional environmental cli⁃mate characteristics,suitable technical measures for dust prevention and suppression were proposed.It provided tech⁃nical reference for dust pollution control of uranium open-pit mining in the North.
