| Abstract: | The authors analyze structural features of U-shaped hard mineral bodies and offer an approach to selecting scenarios of opening-up and sequence of mining at such deposits. It is validated efficient to use draglines for actual mining and overburden removal. The analytical method of finding re-excavation factor in dragline mining is proposed. |
