“…A mining enterprise is interested in improving the reclamation results only if the land quality enhancement rate outstrips the increase in reclamation cost [3]. Therefore, it is necessary to choose such mechanization tools and technology of mining reclamation which will allow to create high fertility soils (primarily for agricultural use), without entailing big production costs for reclamation and payments to compensate agricultural enterprises losses [4].…”

“…So, suitability of lands for agricultural development is determined by the following indicators: capacity of the bulk fertile soil layer, cm; the content (%) and the stock (t/ha) of humus in the bulk soil; the content of physical clay in the bulk and underlying rock, %; average density of black earth mass in a meter-thick bulk layer; the degree of salinization of the black earth layer and the underlying rock. However, the most important is the quality and content of humus in the soil of agricultural land [3]. Accordingly, the technical means of land reclamation must be primarily chosen in terms of the land quality assurance by these two indicators.…”

“…Therefore, when choosing the means for mechanization and technology of the mining stage of dumps reclamation in a particular quarry, one should control their suitability for the application of the required capacity and uniformity of the black earth layer. This should be taken into account when choosing the technology of reclamation works, provided the creation of man-made soils which ensure the highest economic value of the reclaimed land resources [3].…”

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

The ecological consequences of underground coal mining and the mechanisms of transformation of the rock mass and the earth's surface are determined. To increase the efficiency of environmental activities of coal mining enterprises, the expediency of introducing the technology of stowing of the worked-out areas with grouting solutions using rock from dumps, ash, waste from coal processing plants is substantiated. The implementation of the proposed technological solutions will ensure the protection of land, buildings and structures from under-mining, as well as improve the environmental situation in coal mining regions.

Purpose. To substantiate a rational schedule for the combined dragline-truck operation taking into consideration a coefficient of mining in the context of the pit. Methodology. Mathematical and graphical modeling was involved while determining a coefficient of mining concentration in the pit as well as feasibility analysis to select a rational procedure scheme for dragline operation. Findings. Recommendations for the selection of rational dragline operation, while truck loading in the context of Motronivsko-Annivskyi pit, have been developed taking into consideration mining concentration degree in the pit. It has been determined that bottom dragline unloading into a truck, located in the central part of bench mining width, as well as the dragline position at 0.5 A distance from the bench crest, is the most efficient plan of action for the conditions. Technological scheme to develop Motronivsko-Annivskyi pit has been proposed. Originality. Dependence of the mining concentration in the pit upon the parameters of development system elements according to different technological schemes has been derived. The dependence helps estimate development cost for overburden rocks using draglines with direct unloading into trucks. Practical value. Technological schemes for the combined dragline dump truck operation have been developed. Their use makes it possible to cut the prime cost of overburden activities. Implementation of the proposed solutions helps cut stripping cost by UAH 79.65 million a year if annual overburden volume is Qrozkryvu - Qstripping = 13.5 million m3/year.
