中线式尾矿排放工艺在张家口某铁矿的应用

Application of centerline tailing ponding discharge technology in the iron ore plant of Zhangjiakou

结合张家口市某铁矿的矿石特点和矿山周边环境现状,确定新建尾矿库采用中线式水力旋流器排尾筑坝方式,简要介绍了尾矿库主要构筑物的组成,并对中线式尾矿排放工艺进行了详细阐述,实践证明,采用该筑坝方式提高了库容利用率,减少了排尾征地问题,获得了显著的社会效益。

Combining with the iron ore features and surrounding environment status in Zhangjiakou city,the paper determines centerline tailing ponding discharge technology in the new tailing pond,briefly introduces major building components,and illustrates centerline tailing ponding dis-charge technology. Practice proves that：applying centerline tailing ponding discharge technology improves the pond volume utilization ratio,re-duces the tailing land acquisition problems,and achieves obvious social benefits.
