针对南芬铁矿进入凹陷露天开采之后,采场汇水面积大,边坡高陡.地表及地下汇水丰富,采场排水难度大的问题。笔者通过对山坡汇水、地下涌水等方面进行分析计算,提出了层层阻隔疏导、分区分段疏导及利用移动泵站和倒段固定泵站相结合的疏排水措施。 After the Nanfen Iron Mine enters the open-pit open-pit mining, the storage area has a large catchment area with steep slopes, rich surface and underground water catchment, and difficult drainage in the stope. Based on the analysis and calculation of hillside catchment and groundwater gushing, the author puts forward a series of drainage and drainage measures that combine barrier separation, partitioning and diversification and the use of mobile pump station and inverted fixed pump station.
