Purpose. Analysis of the man-made mineral formations of ore mining and smelting, fuel and energy complexes development accumulation, location and prospects amount in the Dnipropetrovsk region.Methods. Comprehensive approach, including analysis of state statistics, waste handling sites (WHSs), regional environmental report, environmental passport of the region, as well as data from other information sources is used in the work. Aerial photographs of man-made formations were obtained using the Google Earth 7.1.8 satellite program.Findings. The analysis of the main man-made mineral formations of ore mining and smelting, fuel and energy complexes accumulation in Ukraine (coal and mining industry waste heaps, tailing dumps, ash dumps, smelter slag dumps) was conducted, their amount and occupied areas were estimated. According to the densest location of man-made formations, they are divided into 4 regions: the Prydniprovsk region, the Kryvyi Rih region, the Nikopol region, the Pavlohrad region. According to information sources, the content of some valuable components in man-made formations has been established. Based on the world market prices of technogenic deposits components research, it was proposed to grade them according to the cost of valuable components. The promising directions have been proposed for the use of mineral resources in various economic sectors. It is noted that from the perspective of development of mineral and raw materials potential, the bulk formations are of interest because of their large reserves in the minimum area. But from the perspective of environmental protection and the interests of the Ukrainian people, the bulk technogenic formations occupying significant areas of agricultural land and having smaller mineral reserves are of great interest.Originality. The conception of man-made raw material mineral fund for further industrial development as an alternative to natural deposits is extended and systematized. For the first time, an integrated and detailed analysis has been performed of technogenic waste of the largest waste storage region in Ukraine, as well as the grouping has been proposed of mining and energy sector waste by density of location and by the contained components value. Practical implications.A sketch-map of the man-made objects location was drawn up and their gradation was carried out according to the preliminary prospects of their development. This will provide a more objective approach to the concept of industrial waste development and planning the strategy for the development of mineral and raw materials potential both at the state and regional levels.

The research on the physical and chemical properties of landfill leachates and migration of its hazardous components into hydrosphere and biosphere is a current problem in the global context. The object of the research is landscape-changing factors of the Lviv municipal landfill (Ukraine). It was defined that the largest part of oil products accumulates in the leachates at the southwestern side of the landfill (23.6 mg/dm 3) and it is 2.36 times higher than the value of the maximum permissible concentration (MPC) (10 mg/dm 3); the most saline leachates with chlorides and sulfites are those accumulating at the foot and at the northwestern side; the phosphate content of the investigated leachate samples was the highest at the foot of the landfill and amounted to 12.8 mg/dm 3 , which exceeds the MPC (10 mg/dm 3) by 1.28 times; high concentration of ammonium nitride was discovered in the leachates at the foot (76.1 mg/dm 3) and at the northwestern side (46.3 mg/dm 3), which exceeds the MPC (30 mg/dm 3) by 2.53 and 1.54 times, respectively; the highest indicators of total iron are typical for basins nearby (at the foot-68.2 mg/dm 3 , at the northwestern side-56.3 mg/dm 3) and exceed the MPC norms (2.5 mg/dm 3) by 27.28 and 22.52 times, respectively. According to certain indicators, the content of hazardous components in the leachates, which accumulate at the foot and at the northwestern side, exceeds the MPC and is several times higher than in the natural basins at the distance of 800 and 1200 m.

The aim of the work is to investigate the influence of man-made edaphotopes of colliery spoil heap on biota by bioindication method. The physicochemical properties of edaphotopes were investigated: humidity, substrate temperature, humus content at different intervals of their depth and on different sections of the waste heap. The storage technologies of mineral waste in the dumps disregard its further use and transforming that occurs over time. It was revealed that on the northern slope exposures the greatest amount of moisture was concentrated and temperature regimes were acceptable for the activity of the soil biota, which was proved by the largest amount of biomass. New dependences of humus content in edaphotopes of the heap in different intervals of their depth from biomass of humus-forming organisms were established. Slight successional processes on the surface of the heap were observed, where young flora began to develop. This positive phenomenon will contribute to the humus of the genetic horizons and the development of tree and shrub vegetation. Favourable conditions for the development of neo-terrain and the formation of a new landscape in mining regions were confirmed.

Novoyavorivsk is located near large sulfur deposits in a transborder with Poland. The existing sanitation system in Novoyavorivsk is imperfect. Municipal wastes are stored in cloughs, ravines, river valleys. This causes an environmental hazard, as polluted wastewater is discharged to the water bodies. The aim of the work is environmental hazard assessment of Novoyavorivsk landfill. The tasks of the research are as follows: determination of chlorides and sulfates content in the landfill edaphotopes; measurement of power of equivalent dose of photon radiation. Determination of chlorides and sulfates was carried out by quantitative and qualitative methods. The equivalent dose of photon radiation was measured by dosimeter by SOEKS USA, LLC. In different sites of the landfill chlorides and sulfates content differs. The most polluted areas are at the distance of 10 m and 50 m from the foot. At a distance of 100 m from the landfill, the concentration of chlorides reduces to 0.001% (5 cm) and 0.1% (10 cm and 20 cm). High sulfate content is observed at 10 m from the foot of the landfill (1% in the 10 cm and 20 cm horizons). The power of the equivalent dose at a height of 10 m from the south side exceeds the pollution standard of 0.3 μSv/h and equals 0.32 μSv/h.

Purpose. Determination of the granulometric characteristics and loosening coefficient of mine rocks formed during stope operations from undercutting the bottom rocks as a potential backfill material based on a set of mine and laboratory research. Methods. To do research, a complex methodology is used, which includes a photographic surveying the mass of destroyed rocks from undercutting the bottom rocks in mine conditions, digital processing and determining the granulometric composition in the software package, sampling the mine rocks at the surface complex, and reconstructing the granulometric composition, similar to the full-scale mine conditions in the laboratory. Sieve analysis, laboratory balance and laboratory container are used to determine the granulometric composition and loosening coefficient. Findings. The dependence between the granulometric composition and loosening coefficient of rocks, which increases by 33% within fractions of 0-50 mm and by 8% within fractions of 50-140 mm, has been revealed. It has been determined that the destroyed rocks in the face within fractions of 0-140 mm have a bulk density of 1.28 g/cm3, loosening coefficient of 1.7, the voidness of and the maximum reserve for the backfill mass compaction with mine rocks is 41.9%. An analytical assessment of the volumes of the formed cavities of the mined-out area in the longwall face and gobed mine workings, as well as the prospects and completeness of their filling with mine rocks have been performed. Originality. It has been determined that the loosening coefficient of mine rocks destroyed in the stope face by KA-200 shearer changes according to the logarithmic dependence on their granulometric composition. This makes it possible to control the granulometric characteristics of the backfill material to achieve the maximum density of the backfill mass. Practical implications. Further research can serve as a basis for determining the rational parameters for the formation and placement of backfill masses during complex-mechanized selective mining of coal seams using various methods of backfilling operations.

The results of the research showed that hydromorphous soils prevail on the territories adjoined to waste heaps. Swampy meadow and sod soils were defined. During investigation of swampy meadow soils it was determined that the soil is humused at a considerable depth. The soils are saturated with the bases. According to granulometric texture it is sandy loam soils, but with depth go to the middle loamy soils. The analysis for labile forms of heavy metals showed that in these soils the content of investigated heavy metals does not exceed the maximum allowable concentrations, except for lead. The amount of humus in sod soils sharply decreases with depth, the reaction is close to neutral. This soil is of slightly heavier granulometric texture. The content of labile forms of heavy metals doesn’t exceed MACs, except for lead.

Purpose. Determination of ecological patterns for vegetation cover formation in the mining waste dumps of the Lviv-Volyn coal basin based on the ecotopes floristic composition analysis of waste heaps reclaimed and non-reclaimed. Methods. The phytoindication of ecological regimes is used based on the ecological parameters of herbaceous species of vegetation covering the mining waste dumps; data retrieval techniques (Data Mining methods); plant species multivariate ordination based on the main components analysis (Principle Component Analysis); statistical processing of ecotopes ecological parameters of the mining waste dumps. Findings. A phytoindication assessment has been performed of the conditions in the places of growing 8 ecological-cenotic groups and 5 subgroups of plant species representing various ecotopes of reclaimed and non-reclaimed waste dumps of mines according to nine parameters: Tmthermal regime, Knclimate continentality, Omombroclimate, Crcryoclimate, Hdsoil moisture, Trsalt content, Rcsoil acidity, Ntmineral nitrogen, Lcluminosity-shadowing regime. It has been found that with decreasing parameters of climate humidity, shadowing in cenosis and soil moisture, the indexes of thermal regime, continentality, soil pH and salt content increase. It is recommended to present the typological scheme of the vegetation covering the mining waste dumps in the form of a quadrangle, in the centre of which meadow and synanthropic vegetation is located, and in the cornersboreal and psammophilous vegetation; nemoral-forest; hydrophilous; meadowsteppe and calcetrophilic. Originality. It has been revealed that the vegetation covering the mining waste dumps of the Lviv-Volyn coal basin is characterized by an ecological-cenotic areal. It has been assessed on the basis of the species ordination on the axes of complex environmental gradients, and the center of this areal is occupied by meadow and synanthropic species, which demonstrate greatest sustainability under the conditions of mining waste dumps. The most vulnerable species are meadow-steppe, calciphilous, hydrophilous vegetation, the ecological-cenotic areal of which is characterized by the location on the periphery of the general vegetation areal of mining waste dumps. Practical implications. The ecological parameters of flora species make it possible to determine their position in the ecological-cenotic areal of vegetation covering the mining waste dumps of the Lviv-Volyn coal basin, as well as to predict their sustainability and dynamics.
