Abstract
The authors discuss reduction of stripping in deep-level open pit mining by making the open bottom wedge-shaped. The article describes the calculation scheme and the correlation analysis of interaction between stripping amount and its determinants. The application constrains for the wedge-shaped open pit bottom are specified.
