五、采矿方法克里沃罗格采选联合企业的各露天矿开采倾斜和急倾斜含铁石英岩厚矿床,所采用的采矿方法,是用铁路和汽车,把废石运往外部排土场的一些运输采矿法。把这些采矿方法区别开来的主要特征,是电铲工作面和露天矿工作钱的推进方向和推进性质。从这个特征来看,克里沃罗格矿区露天矿的采矿方法可以分为两种:一种是各水平纵向采准和工作钱横向推进的采矿方法,另一种是各水平无开段堑沟的横向采准和工作线纵向推进的采矿方法。南方和新克里沃罗格两采选联合企业露天矿采用第一种采矿方法,并用铁路运输,入车
V. Mining Methods The open pit mines of the Kerry Voroga Mining and Dressing Complex are used for the mining of thick and plunged quartz-bearing quartzite deposits. The mining methods used are railways and vehicles to transport waste rock to an external dump Some transport mining laws. The main features that differentiate these mining methods are the propulsion and propulsion nature of working surfaces for shovels and open-pit mines. From this characteristic point of view, the mining methods of open pit mines in Krivoy Rug can be divided into two types: one is horizontal mining with horizontal mining and horizontal mining and the other is horizontal mining without cutting Trench horizontal mining and work-oriented vertical approach to mining methods. The first mining method was adopted for the open pit mine in the South and New Krivoy Roggean mining complexes and was transported by rail and entering the train
