Abstract
The article presents argumentation in favor of transition to high bench stripping in open pit mines in Kuzbass, which will increase coal production and improve mine performance. The authors find functional connection between the duration of the transition to high bench stripping and the increase in the finite depth of an open pit mine. Substantiation is given to choosing the height of a bench based on the change in relationship of operating costs and a cut layer height. The practical significant of the research is development of a new approach to validating expediency of high benches for mining with truck&shovel and creation of a procedure to find increment in ultimate pit contour in transition to stripping with high benches.
