Abstract

The article discusses capacities and benefits of stripping with direct dumping within the mixed-type mining technologies for structurally complex deposits of solid minerals. The authors emphasize practicality of this technology in different geological and geotechnical conditions of mineral mining, and develop a procedure to determine a reasonable application range of the technology within the mixed-type mining systems. The resource-saving process flowsheets are proposed for dragline mining of centroclinal fold-type, water-encroached and steeply dipping bedded deposits. The most feasible ways of enhancing efficiency of overburden removal with direct dumping are discussed.
