虹吸原理在胜利露天煤矿防治水中的应用

Application of siphon principle in Shengli open-pit coal mine water control

在总结多年防治水工作经验的基础上,胜利露天矿参照虹吸原理,采用聚乙烯塑料管路疏排南北端帮涌水。在内排土场的防治水工作中将疏干井中经常使用的过滤器与虹吸排水管路相结合,在排土场内部形成一套地下排水系统,将内排涌水疏排至采场集水仓后进行统一排放,提高内排土场稳定,防止发生局部滑坡等问题。

On the basis of water control work experience for many years, Shengli open-pit mine adopts polyethylene pipes for water drainage in North and south ends consulting siphon principle. In internal dump water control work, the mine combines the filter and siphon drainage pipeline in drainage wells and forms a set of underground drainage system, which uniformly discharges internal dumping water drainage to stope drain sump to improve the stability of internal dump and prevent the occurrence of local landslide.
