“…The percentage content of the mineral Mt (magnetite) in the studied fraction of a potential technogenic deposit consisting of several mineral components is determined by the formula CMt = Mt/(Mt, Q, Bt, Pr...) (2) where CMt is the magnetite content, in unit fractions; Mtmagnetite, Qquartz, Btbiotite, Prpyrite; (Mt, Q, Bt, Pr...)sum of all values.…”

“…In the world, a lot of attention is paid to the issue of determining the tailings accumulative capacity, their residual capacity and recovery options. The author [2] investigated the interaction of disturbed and man-made massifs with the natural geological environment and proved that this leads to the development of negative processes in the structures of tailings storage facilities. As a result, it is concluded that it is better to mine storage tanks instead of building dams.…”

In Ukraine, a significant mass of potential man-made deposits is represented by waste from ferruginous quartzite enrichment. The mineral mass of such deposits is mixture of iron-containing minerals (magnetite, ilmenite) and quartz. The M.S. Poliakov Institute of Geotechnical Mechanics has developed a new methodology for the mineral components spatial distribution predicting in tailings of ferruginous quartzite enrichment. It includes the fractional and mineralogical composition of the samples study by optical method, and spatial useful components distribution of prognostication in waste and predictive plans construction for the useful components spatial placement. A previously unknown pattern of changes in mineral composition of wastes from mining ore production was revealed which caused by the turbulent transportation mode and waste deposition on the tailing (potential man-made deposit) area. This regularity arises from the fact that with decrease in the size of the mineral components particles with size of 0-200 microns, the share of the magnetic mineral magnetite increases linearly and, accordingly, the share of the non-magnetic mineral quartz decreases. The obtained new properties of man-made deposits from the waste (tailings) can be used in creation of resource-saving technology for the iron ore man-made raw materials processing and to determine their suitability for mining.

“…In turn, these negative processes lead to the emergence of secondary disturbances in the natural environmentdirectly in disturbed and technogenic massifsadditional sedimentation and deformation of rocks, down warping etc. [15]. The scientific literature focuses on the environmental consequences of the opencast mining development, economic and technological problems caused by the destructive impact of mining enterprises on the environment [16] [20].…”

Purpose. Theoretical substantiation of principles and development of recommendations for the choice of technological variant to form the quality of lands of technogenic origin, which would ensure rational spending of funds allotted for reclamation and preservation of the reclaimed lands suitability for agricultural use with the highest requirements for agrophysical soil characteristics. Methods. The following methods were used in the process of the research: the method of theoretical generalization and systematization (to determine the characteristics peculiar to the formation of qualitative characteristics of man-made soil using mechanization of reclamation works), analytical (to determine the factors influencing the effectiveness of land reclamation in opencast mining), comparison (to analyze the efficiency of different versions of reclamation works mechanization). Findings. The influence of technical means of reclamation works mechanization on the quality of lands subject to restoration in conditions of opencast mining is analyzed. A methodological approach to the choice of mechanization of land reclamation works in respect to the indicators of the formed quality of technogenic agricultural lands as a factor of their monetary valuation and the level of costs for their reproduction is proposed. Recommendations for quality management of man-made lands by technical support of the process of their consumer properties formation, aimed at achieving a favorable ratio between quality and, accordingly, monetary valuation of man-made lands, on the one hand, and, on the other, – the cost of their reclamation. Originality.A scientific and methodological approach to the choice of technical equipment for reclamation works is proposed, where two factors are considered: reclamation costs and quality of man-made lands, which allows to determine the priority of cost savings or land quality improvement according to the target criterion of reclamation works efficiency. Practical implications. The obtained results are aimed at improving the methodological bases for management of the man-made lands reclamation process based on the choice of its mechanization means. Keywords: land quality, reclamation costs, monetary valuation of lands, reclamation technology, reclamation efficiency

“…Significant waste generation is also formed as a result of underground mining operations. As a result, waste accumulations in the form of waste rock dumps, which occupy about 7 thousand hectares, are formed on the surface [29], [30]. Today, when mining 1000 tons of coal, the waste rock yield is 500 tons.…”

Purpose. Study the movement of waste rock flows in the coal mine technological system and determine the balance of rocks and underground cavities formation from the perspective of the current mining operations development in order to assess the possibility of leaving the rock in the underground area. Methods. Based on the rank order of the Western Donbass mines, a coal mine has been chosen as the object of research in terms of maximum output and ash content. An algorithm is proposed for analytical studies of determining the rock outcrop in the course of stope, drifting and repair operations, as well as the prospective volumes of underground cavities for placing the formed waste rocks per a calendar year. The algorithm is based on the actual state of mining operations and the indicators of the stope and drifting faces of the mine, as well as the achieved modern mining-engineering parameters of the coal seams mining. Findings. It has been revealed that the main supply of waste rocks to the surface occurs as a result of stope operations with rock undercut -39% and underground mine workings -33%. It is proposed to differentiate all waste rock outcropped after mining operations into 2 categories: difficult to dispose of and prospective for disposal. It has been found that underground cavities have enormous potential for stockpiling of all waste rocks, the volume of which is by 2.8-4.8 times higher than the rock volume. It has been revealed that the most rational balance of waste rocks and cavities for leaving the rock in the mine is formed along the С 10 t seam. It has been determined that the full-fledged placement of rocks is limited by the scheduling peculiarities of mining the reserves along the seams, which are made for the complete cave-in technology of coal mining. Originality. For the first time, for one of the Western Donbass mines, the balance of formed waste rocks and potential underground cavities, dynamically changing in time and space, has been determined. Practical implications. The results obtained are useful for engineering new spatial planning solutions for the optimal development of mining operations with the maximum possible rocks stockpiling in the underground area of mines.
