On the internal ordering of technogenical accumulations of the «Pivnichnyi» quarry of c. Kryviy Rih

The research was carried out within the «Pivnichnyi» iron ore quarry in the city of Kryvyi Rih with the aim of the comprehensive and effective further use of the technologically transformed areas of the subsoil and the Earth’s surface of Kryvbas. The fixation of bedding elements in relatively undisturbed blocks of quartzites and shales of the Saksagan suite and technogenic accumulations was carried out. In relatively undisturbed blocks of quartzite, such elements for banding, schistosity, linearity of mineral aggregates, axes of folded forms, striation, furrows, etc., were measured. Among technogenic accumulations (scree slope, embankments and filled artificial cavities), according to the degree of structuring, unstructured and structured accumulations to varying degrees were observed. Layering, mechanical schistosity and linearity were fixed within them. Layering, mechanical schistosity and linearity are fixed within them. The emergence of newly formed planes of technogenic accumulations, in almost 70% of cases, took place with the inheritance of the structural anisotropy existing in the surviving blocks with the creation of its own stratification. Therefore, the man-made geological formation under study consisting of relatively undisturbed blocks of bedrock and man-made accumulations, is a system: «surviving block–technogenic accumulations», which developed and formed as a whole object, mutually coordinated, over years–decades in surface conditions. The formation of the system of blocks of the «Pivnichnyi» quarry (both the actual surviving blocks and the planes of structuring of loose accumulations) occurred due to displacement relative to the vertical and horizontal axes. The transformation of technogenic accumulations, their «completion»/structuring, as a result of which the integrity of disturbed and missing areas of the geological volume is restored, are constructive phenomena. They are practically a natural laboratory of processes of formation of structural and textural elements in loose accumulations. Their tracking in time would make it possible to actually observe the processes of self-creation/reproduction of modern technogenic-natural objects. The ranking of structural neo formations in technogenic accumulations can be used as one of the criteria for assessing the assimilation potential of these accumulations and their suitability for economic reclamation.
