尾矿库干滩扬尘的湿盖固化方法研究

Prevention and control method of fly ash in tailing dam

尾矿仓库是金属、非金属矿山所需的生产设施。目前全国各地有一万多座尾矿库,每年都有大量尾矿排入尾矿库中。尾矿库对矿山的生态环境影响很大,其中尾矿库的扬尘是造成矿山环境污染的形式之一。本文提出尾矿库干摊扬尘防治的伸缩柱架式微喷水法及用微喷法建立的表层防护湿盖,用于防护尾矿坝表面扬尘。

Tailings warehouse is a production facility for metal and non-metal mines.There are currently more than 10,000 tailings ponds across the country,and a large amount of tailings are discharged into the ponds every year.Tailings pond has a great impact on the ecological environment of mines,among which tailings pond dust is one of the forms of mine environmental pollution.In this paper,the telescopic column frame micro-water spraying method and the surface protective wet cover established by micro-jet method are put forward to prevent the dust on the surface of tailings dam.
