在库尔斯克磁力异常区斯道依林斯克露天矿,富铁矿和含铁石英岩矿床的疏干是用综合方法完成的,即:使用降水钻孔和直通式过滤器,同时也应用有上向钻孔的地下综合排水设施。采用这些方法可消除水压和降低地下水水位。与此同时,地下水总涌水量的相当大部分却流进了露天矿坑和排水明沟。在斯道依林斯克露天矿的条件下,地下水从露天矿边帮渗出会造成一系列不良后
In the Staullinsk open-pit mine in the Kursk magnetic anomaly, the dewatering of iron-rich ore and iron-bearing quartzite deposits is accomplished by a combination of methods, namely, the use of precipitation drills and straight-through filters, as well as Bored underground drainage facilities. Using these methods eliminates water pressure and groundwater levels. In the meantime, a significant portion of the total groundwater inflow has run into open pit mines and ditches. Under the condition of the open-air mine in Staullinsk, the seepage of groundwater from the open-pit side can cause a series of poor
