摘要
露天煤矿因长时间大流量疏排地下水给矿区生态环境、煤矿生产安全和企业经济效益等方面带来一系列问题,采用防渗墙技术对渗流补给通道进行帷幕截流可有效减少煤矿疏排水量,达到保护矿坑外围生态环境、实现煤矿安全生产的目的.对露天煤矿防渗墙构建条件与类型进行研究,并提出不同类型防渗墙适用条件,对露天煤矿防渗墙建设具有理论指导意义.
In order to solve a series of problems such as ecological environment,production safety and economic benefits caused by groundwater draining in open-pit coal mines,the diaphragm wall technology was used to cut off the seepage supply channel,which can reduce the drainage effectively,protect the environment outside the mine and realize safe product.Researched the basic construction conditions and types of the diaphragm wall and proposed the applicable conditions,it has theoretical guiding significance for the construction of diaphragm wall in open-pit coal mines.
