Abstract
The analytical results are given for application of stripping with direct dumping in open pit mines in Kuzbass. It is emphasized that this most productive and the least power-consuming technology loses its weight in the overall content of overburden stripping. The authors propose a method to determine rational boundaries for application area of stripping with direct dumping using slice re-excavation coefficient. The scope of the discussion comprises potential trends of the technology and use of draglines towards enhancement of open pit mining efficiency.
