ABSTRACT

Purpose. Complication of the conditions of conducting open-pit mining operations and complex external factors will certainly lead to the deterioration of technical and economic indicators of deposit development in the future. The complex development of deposits is one of the promising options for correcting this situation, and the purposeful formation and development of man-made deposits is the main way of expanding the mineral and raw material base of Kryvbas. The purpose of this work is to generalize the experience of developing Kryvbas tailings and theoretical approaches to the formation of schemes for complex mechanization of their processing for the further creation of a scientific basis for the expansion of the raw material base of the Kryvorizka mining complex.

Methodology. The work uses the methods of analysis and synthesis of literary sources of information when assessing the state of complex development of deposits in the Kryvyi Rih region, retrospective analysis of project decisions regarding PRJSC "Central GZK", engineering analysis - when assessing the schemes of complex mechanization of tailings storage facility.

Results. The analysis of scientific sources was carried out and the state of complex development of deposits of Kryvbas was assessed. Accumulated volumes of magnetite quartzite dressing waste have been determined. The experience of the development of man-made deposits of the alluvial type was analyzed, during the design analysis the most appropriate schemes of complex mechanization and the parameters of the tailings storage development system were identified.

Scientific novelty. The conducted retrospective and engineering analysis of design solutions made it possible to identify the most effective schemes for complex mechanization of tailings disposal. As the most expedient in the conditions of PRSC "Central GZK" was chosen a scheme using a dredger with subsequent transportation of man-made raw materials to the pulp farm.

Practical significance. The results of the performed research can be used by design organizations and mining enterprises when designing the formation and development of tailings storage facilities.

Keywords: man-made deposit, tailings storage facility, dredger, scheme of complex mechanization, complex development of mineral deposits.
