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 to be efficient to use draglines for actual mining and overburden removal. The analytical method of finding reexcavation factor in dragline mining is proposed.
