JUSTIFICATION OF STRUCTURING TECHNOGENIC ACCUMULATIONS OF IRON ORE QUARRIES IN KRYVORYZHJA
Abstract. Previously, in the technogenic geological bodies of the iron ore pits “Pivnichny” and “Pivdennyi” (near the city of Kryvyi Rih), newly formed textures were discovered: layering, banding and linearity. They are noted in 65% of the studied objects (dumps, screes, embankments, etc.); the elements of the occurrence of these new formations in 68.75% of cases inherit the spatial orientation of the bedrock in the pillars. This work systematizes data on the reasons for the structuring of technogenic accumulations according to previous researchers and our own observations. Three key processes have been identified that contribute to the emergence of layering and other structures in technogenic accumulations of quarries. These are: technological processes of extraction and storage of material, internal processes in the bulk mass and external environmental influences. It is concluded that there is a “geodynamic interaction” between the man-made object (the quarry and its waste heaps) and the natural geological environment (bedrock). Such interaction is manifested in the transfer and modification of stresses and deformations, which have a direct effect on the formation of new structures in the waste heaps, forcing them to inherit the orientation and symmetry of the bedrock. All of the above creates a single man-made-natural system that is actively evolving in search of a new dynamic equilibrium. The study of man-made new formations in the waste heaps of iron deposits has significant scientific and applied potential.
Keywords: newly formed textures, man-made accumulations, systematization, reasons for structuring, geodynamic interaction.
