Research of land-saving schemes of mining the horizontal sedimentary mineral deposits

Technological mining transport schemes of open development of horizontal sedimentary deposits are considered. Various land-saving technological schemes for transportation of minerals in the absence of a capital trench have been developed. The dependence of the mineral transportation cost on the production capacity of the mine for the developed schemes was established. The research has been carried out for conditions of surface mining manganese deposits of Nikopol Basin. Transport schemes using mobile steeply inclined conveyor are offered. The developed technological solutions for the conditions of surface mining of deposits of the Nikopol manganese ore basin allow not only to reduce the amount of disturbed land, but also to reduce the cost of minerals by reducing its transportation distance by 2 km. The proposed transport schemes will make it possible to obtain an economic effect in the amount of 1–3 million UAH.

The suitability of physical and chemical properties of rocks for land reclamation in different subzones of the Ukrainian Steppe


 
 
 The study of the properties of disturbed soils and rocks makes it possible to establish the parameters of the natural fertility of the studied substrates, to detect limiting factors, and to determine a set of restoration measures. The tested overburden rocks with the largest stratigraphic share of the open-pit quarries of the Nikopol manganese and Kerch iron ore deposits were loamy-like loess (Quaternary) and grey-green clay (Neogene). There is a certain parametric relationship between texture, density, porosity, the structural and physical state of different models of artificial reclaimed profiles. The composition and properties of rocks of edaphic structures of technosoils differ according to zonal natural and climatic conditions of the subzones of the Ukrainian Steppe. Loess-like loam and grey-green clay of the Kerch iron ore deposit are distinguished by a higher bulk density, lower porosity, and wilting moisture compared to samples from the Nikopol manganese ore basin. The use of the rotor complex leads to mechanical destruction and an increase in the content of small particles of rocks. Self-compacting processes occur to a large extent in multilayer structures. This pattern is observed at the boundary of the backfill differentiated in texture layers of technosoils. This indicates the existence of a barrier that prevents the relationship of edaphic properties between substrata stratums. Optimal ratio of clay minerals provides a rather high capacity of grey-green clay for water absorption. The model of technosoil composed of grey-green clay differs in a larger number of water-resistant micro-aggregates. The best conditions for land reclamation are connected with including grey-green clay in two- and three-layer constructions of technosoils, providing a waterproofing effect.

Environmental Aspect of Population Organisation of Terrestrial Mollusk Brephulopsis cylindrica (Pulmonata, Buliminidae) in Space and Time at a Remediation Territory (Nikopol Manganese ore Basin)

Abstract Density variability of a population of the mollusk Brephulopsis cylindrica (Menke, 1828) was studied at a reclaimed site in the Nikopol manganese ore basin. This study was conducted on sod-lithogenic soil on grey-green clay. The samples were collected over 3 years, 3 times a year, on a regular grid. Lexis aggregation index (λ) and geostatistical tools were used to characterise spatial distribution of the mollusks. The correlation between the distribution of B. cylindrica and environmental factors was established using correlation analysis. Valid correlations were identified between distribution of the mollusk and variation of the fraction content in composition of structural aggregates of soil. Also, valid correlations were identified with plant species composition at the reclaimed site.

Major, trace and rare earth element (REE) geochemistry of the Oligocene stratiform manganese oxide-hydroxide deposits in the Nikopol, Ukraine

The Nikopol manganese deposit is situated in the west and north of Nikopol, Ukraine and one of the world's largest deposits among the sedimentary manganese deposits. The Nikopol Oligocene basin consists of two structural stages, Precambrian crystalline basement rocks and sedimentary cover rocks (Cretaceous to Quaternary). Nikopol Ore horizon is traced in a thickness varying from several cm to 4.5 m and a single stratum from the west to the eastwards to about 250 km. Nikopol manganese ore horizon was separated to three different units; carbonate ore, mixed carbonate-oxide ore, and oxide ore. The main minerals of supergene oxidation zone in Nikopol manganese deposits are: manganite, pyrolusite, todorokite, cryptomelane, birnessite, rancieite. The manganese oxide-hydroxide ores were analyzed for major oxides using ICP-AES and, trace and rare earth elements (REE) using ICP-MS. The mean major oxide contents of the manganese ores are 40.7 wt% MnO, 4.1 wt% Fe2O3, 15.6 wt% SiO2, 4.17 wt% for Al2O3, and 7.1 wt% for CaO. The average Mn/Fe, Co/Ni, Co/Zn, and Zr/Hf ratios in the Nikopol manganese deposit are 25, 0.54, 1.15, and57, respectively. The total REE contents are between 60 and 197 ppm, with a mean of 108 ppm. The PAAS-normalized REE patterns of the Nikopol manganese oxide ores have similar trends and show MREE (middle rare earth element) and HREEs (heavy rare earth element) enrichments. The Ce/Ce* values of manganese oxide-hydroxide ores collected from the study area vary from 0.88 to 1.43, with the mean of 1.16. Most of manganese samples have positive Ce anomalies except for a few samples, indicating that ore-forming rocks were primarily marine chemical or biogenic deposit. The Eu/ Eu* anomalies of the manganese oxide-hydroxide ores are close to 1 with a range of 0.68 to 1.12 (mean: 0.96). The Y concentrations vary from 9.1 to 47.1 ppm, with an average of 18.2 ppm and show negative Y anomalies, except for three samples. The Pb isotope ratios are 19.0 for 206Pb/204Pb, 15.7 for 207Pb/204Pb and 39.4 for 208Pb/204Pb isotopes. All these data indicate that the Nikopol manganese oxide-hydroxide ores formed rapidly within oxic/suboxic seawater as reflected by Ce anomalies close to 1 in compared to similar environments, low-oxygen fugacity in source of the hydrothermal fluids, volcanogenic input or hydrothermal contributions to seawater, and high Co, Ni, Cu, Sr, Ba and As and low V, Rb, Nb, Hf, U, Th, Pb and Zn values. Also, our results point out that the metals were transported from both a hydrothermal source in deeper water (chemical discrimination diagrams) and terrestrial sources (Pb isotopic data). The metals formed to the Mn-oxide ores syngenetically likely came from water depths deeper than the area where the carbonate-ore deposits formed.

Diversity of cyanobacteria and algae in dependence to forest-forming tree species and properties rocks of dump

Restoration of ecosystems on the lands disturbed by the mining industry is very slow. Acceleration of these processes is the main purpose of revegetation measures. The purpose of the current research is to show changes of cyanobacteria and algae diversity and abundance depending on the composition of different reforested stands and technosols qualities of the waste rock dumps in West Donbas coal basin, Nikopol manganese ore basin and Kryvyi Rih iron ore basin (Ukraine) that were revegetated in 1966 and 1975. The main technosols physical and chemical qualities, diversity and abundance of cyanobacteria and algae are identified. It is discovered that abundance and diversity of cyanobacteria and algae depends on qualities of soils and forest-forming tree species. The increase in physical clay in soils (particles < 0.01 mm) has a positive effect on cyanobacteria diversity and development, the increase in humus effects positively species diversity of yellow-green and green algae. A higher pH intensifies development of cyanobacteria. Development of groups of cyanobacteria and algae shows dependence on the composition of forest-forming tree species and on their environment-forming impact. The environment-forming impact depends on properties of soils and decreases under the unfavourable conditions. Our study proved that the composition and quantity of cyanobacteria and algae have relation to forest-forming tree species and properties. The results can be used for the structural design of artificial edaphotopes, for a choice of forest-forming tree species that have a high capability to create forest ecosystems equivalent to natural ones.

The purpose of the article is to investigate the peculiarities of the modernization of the South-East region of Ukraine in the latter half of the 19th and at the beginning of the 20th century as well as to specify the contribution of entrepreneurs in the formation of the production industry. Methods of research: analysis and synthesis of available information, logical-analytical, problematic-chronological, system-structural methods. The principles of historism, objectivity and consistency, which were the basis of the indicated research methods, made it possible to consider the essence of processes and phenomena, to keep track both of the manifestations of general patterns in the socioeconomic processes in the development of the South-East region of Ukraine and their specific character under the influence of entrepreneurial activity, and also to draw certain conclusions. Key findings: the contribution of entrepreneurs of the South-East Ukraine, which became an important factor in the acceleration of socioeconomic modernization during 1861–1914, is highlighted in the article. Heavy industry became the basis for the modernization in the context of reforms in the latter half of the 19th century, namely production industries related to the extraction of minerals and their processing. During this period, three powerful industrial centers formed: Donetsk coal and metal, Kryvyi Rih ironstone and Nikopol manganese. An important feature of the entrepreneurship development in the South-East region of Ukraine in 1861–1914 was the representation of all population strata: peasants, Cossacks, townsmen, intellectuals, merchants, nobles and foreign capital. They acted as private businessmen and co-owners of collective enterprises. The most common organizational form of entrepreneurship in this period were joint-stock companies, the role and number of which was constantly growing. Conclusions. At the beginning of the 20th century, the Donetsk and Krivyi Rih region became a powerful center of heavy industry (coal, metallurgy, metalworking, machine-building, and chemical). The result of entrepreneurial activity was an increase in production volumes, profitability, the creation of a large number of jobs, the improvement of organization and production technology. Practical value: is determined by the emphasis of the researchers on the need to comprehend the phenomenon of entrepreneurship, its historical lessons, taking into account the powerful factors of this phenomenon and its influence on the contemporary and future civilization development of Ukraine; it is recommended to be used by authors for writing articles, manuals and for development of special courses. Scientific novelty: consists in formulating and studying a relevant topic, which has not received a comprehensive study in historical science. The independent role of entrepreneurship in the capitalist economy at the regional level is shown for the first time; it was proved that the South-East region of Ukraine was the one where the preconditions for the development of private initiative were formed, and also the spread of market relations and entrepreneurship took place; the participation of entrepreneurs in economic modernization as well as the most profitable branches in the region are characterized. Originality: the generalization of experience, practices of profit-making economy of the entrepreneurial strata of the region is used. Type of article: descriptive.

У статті наведені результати дослідження динаміки видів наземних безхребетних у градієнті часу в техноземах Нікопольського марганцеворудного басейну. Дослідження проведене в Дослідницькому центрі Дніпровського державного аграрно-економічного університету (м. Покров, Україна) протягом 2013 – 2015 рр.. Відбір зразків було зроблено на варіантах штучних ґрунтів (техноземів), які сформовані на лесоподібних суглинках, на червоно-бурих глинах, на сіро-зелених глинах, на технологічній суміші гірських порід та на лесоподібних суглинках із гумусованим верхнім шаром. Для дослідження просторово-часової мінливості чисельності, видового багатства та видового складу угруповання безхребетних у межах експериментального полігону, тварин було зібрано зі застосуванням пасток Барбера. Досліджено сім груп безхребетних, близько пов’язаних із ґрунтовим середовищем та наземним рослинним покривом: (1) молюски (Mollusca: Gastropoda), (2) павуки (Chelicerata: Arachnida), (3) двопарноногі (Myriapoda: Diplopoda), (4) губоногі (Myriapoda: Chilopoda), (5) мокриці (Malacostraca: Isopoda: Oniscidea); (6) комахи (Tracheata: Isecta). Встановлено, що динаміка в часі протягом вегетаційного сезону чисельності найбільшої кількості видів безхребетних ділянки рекультивації описується бімодальною асиметричною моделлю (модель VII з переліку HOFJO). Бімодальність підкреслює важливість впливу біотичних (конкурентних) взаємодій між видами. Бімодальність може бути наслідком біологічної неоднорідності популяції та результатом міграційних процесів. Встановлені типи часової динаміки безхребетних вказують на наявність складних та сформованих процесів регулювання чисельності тварин на порівняно молодих екологічних утвореннях, якими є техноземи. Часова динаміка видів безхребетних структурована в просторі та характеризується наявністю регулярних часових патернів, на основі яких встановлені такі фенологічні групи тварин: весняні, літні, літньо-осінні та осінні. Фітофаги переважають серед літньо-осінніх форм, а зоофаги – серед осінніх, та меншою мірою серед весняних або літніх. Відгук літніх форм у градієнті часу найчастіше описується симетричною дзвіноподібною моделлю V. Літньо-осінні форми характеризуються відгуками на час, які можуть бути описані моделями V, VI та VII. Весняні форми найчастіше мають розподіл, який найкраще описується моделями ІІ та ІІІ. Для літніх форм характерна модель VII.

Fitting Competing Models of the Population Abundance Distribution: Land Snails from Nikopol Manganese Ore Basin Technosols

Abstract This paper examines the temporal dynamics of terrestrial mollusks of the Nikopol manganese ore basin technosols. The research was carried out at the Research Centre of the Dnipro Agrarian and Economic University in Pokrov (Ukraine). Sampling was carried out in 2012–2014 on four variants of artificial soil: formed on red-brown clays, on loess-like loams, on gray-green clays, and on humus-rich layer. The distribution of the number of individuals in a mollusk population was described by broken stick, Motomura, log-normal, Zipf, and Zipf-Mandelbrot models. It was shown that the series of models that best describe mollusk abundance distribution is specific for a particular species and technosols type and generally is invariant over time.

The temporal dynamics of readily available soil moisture for plants in the technosols of the Nikopol Manganese Ore Basin

The restoration of a stable and productive ecosystem after drastic disturbances to the natural environment due to mining and open-cast mining may be achieved by means of reclamation. Investigation of the hydrological budget of technosols is important task in developing adequate approaches to reclamation. Sod lithogenic soils on red-brown clay, on grey-green clay were chosen as the objects of the investigation. The simulation of moisture content in Nikopol Manganese Ore Basin technosols was performed using the Penman-Monteith approach and evaluated the role of the dependence of soils’ surface albedo on the humidity in the intensity of evapotranspiration. The research was conducted during 2013–2015 at the station for research on reclaimed land within the Nikopol Manganese Ore Basin (city Pokrov, Ukraine). The experimental area for the study of optimal modes of agricultural reclamation was created in 1968–1970. Precipitation in the investigated area was found to fall very unevenly in time. In 2013, the duration of the rainless period was 259 days, in 2014 – 264 days, in 2015 – 261 days. The maximum daily rainfall varies within 18–49 mm. There are significant interannual differences in the intensity of rainfall. The minimum total annual precipitation in 2014 was due to a decrease in atypical rainfall in late winter and early winter. The maximum annual rainfall in 2015 was caused by intense rainfall both in the spring and in mid-summer and late autumn. The average annual temperature was 11.1 ºC and the annual totals did not statistically significantly vary within the study period. The average wind speed and average atmospheric humidity are statistically significantly different from year to year. The technosols’ colour properties and surface albedo varied depending on the moisture content. There is a linear relationship between the moisture content in the soil and albedo of the soil surface. The evaluation of readily available water content was carried out based on the Penman-Monteith model taking into account meteorological data, the water-physical properties of the technosols and the dependence of soil surface albedo on soil humidity. The distribution of this index for different teсhnosols is characterized by a high level of similarity of shape due to the fact that the overall climate factors are crucial in shaping the dynamics of moisture. A complex mixture of normal distributions is the best model for representing the experimental data. The readily available water content distribution can best be represented as a mixture of two normal distributions. The relatively high moisture level is characterized for winter and spring periods. Water content in sod-lithogenic soils on red-brown clay over the period of research never reached the value of the permanent wilting point. In 2013, the period when the moisture content was less than the value of the permanent wilting point lasted 23 days, and in 2014 this period lasted 39 days. Thus, you can always expect the phenomenon of drought under typical climatic conditions for the technosols on grey-green clay. It was found that monitoring water supplies before the start of the growing season can provide valuable information necessary for the selection of crops for cultivation in the current year. The results indicate the urgency of measures to save the winter rainfall on the fields.

Ecological features of urease activity distribution in technogenically altered soils of the Nikopol manganese ore basin

The challenge of degradation of natural ecosystems because of human activity is considered by the world community to the most serious problems facing mankind. As a result of mineral extraction, man-made landscapes and environmentally ruined areas replace natural habitats and agroecosystems; a whole spectrum of man-made processes are typical for such landscapes, which leads to a decrease in species richness and biological diversity within such areas. Degraded territories formed in the process of coal mining are often partially restored through remediation measures. During the implementation of the technical stage of remediation, substrates with different potential fertility having different environmental properties and quality are used. Specific features of distribution total, available nitrogen concentrations and levels of urease enzymatic activity at the layers of artificial soil, sod-lithogenic soils onto gray-green and red-brown clays and on loess-like loams in the Nikopol manganese ore basin are established. It is presented general assessment of technosol status by concentration of general easily hydrolysed nitrogen enzyme activity of urease and this enzyme enriches the soil with mineral nitrogen in the process of mineralization of organic substances. The level of activity of urease, investigated soils, determines the intensity of the direction of biochemical processes that affect soil fertility.High correlation between concentrations of soluble nitrogen and urease activity values by layers of artificial soil (r = 0.81), sod-lithogenic soils onto gray-green (r = 0.98), red-brown clays (r = 0.72) and onto loess-like loam (r = 0.85) were found. Tendency of decreasing hydrolytic enzyme activity, urease, with depth in all types of artificial soil studied was established. It has been established that biochemical diagnostics of technozem processes beyond the level of activity of the hydrolytic enzyme urease makes it possible to estimate the direction of changes at the layers of artificial soil, sod-lithogenic soils onto gray-green and red-brown clays and on loess-like loams. The recultivated soil has some what lower fertility and greater salimity at the lower horizons, but is capable of performing ecological functions and can not only be used for economic purposes, but also perform ecological functions.

Часова динаміка чисельності популяцій молюсків техноземів Нікопольського марганцеворудного басейну

The regularities of the dynamics of terrestrial mollusk populations that have formed on the artificial soil-like structures: on pedozems and sod-lithogenic soils on red-brown clay, gray-green clay and loam loesses-like clays were revealed. The studies were conducted during 2012–2014 years on the remediation station of Nikopol manganese ore basin in Pokrov. Each site within the ranges studied was examined three times a year: in spring (early May), summer (end of June) and autumn (late September - early October). Within tehnozems investigated it was found the presence of four species of terrestrial molluscs: Brephulopsis cylindrica, Monacha cartusiana, Chondrula tridens and Helix lucorum. The number of shellfish in the investigated B. cylindrica biotopes ranges from 3.68 ± 0.43 to 74,55 ± 4 46 ind. / m 2 . The most favorable conditions for this type of snails are formed in the sod-lithogenic soils to gray-green clays and loesses-like clays. A common feature is the tendency to reduce the number of shellfish throughout the year. Number of clam M. cartusiana investigated in habitats in the range from 2.25 ± 0.27 to 18.64 ± 1.08 ind./m 2 . The most favorable conditions for this species of snails are formed in sod lithogenic soils on loam and loesses-like clays on red-brown clays. The general trend is a decrease in the number of shellfish in the summer and the number of stabilization during the summer and autumn. Number Ch. tridens ranges from 1.38 ± 0.20 to 11.90 ± 1.06 ind./m 2 . The greatest population density Ch. tridens for sod-lіtogennih loam soils on loesses-like clays. The seasonal aspect of population dynamics is characterized by the maximum and minimum spring – summer. Mollusk Helix lucorum consistently found in sod-lithogenic soils on loams and often loesses-like clays consistently met in 2012 and 2013. in the biotope at the gray-green clay. The results can be applied to solve problems zoological tehnozems diagnosis. Also a promising area of research is to assess the functional role of terrestrial molluscs community structure mezopedobionts tehnozems. The knowledge of the dynamics of terrestrial molluscs community will help address issues of management functional properties recultozems models.

Динаміка вмісту карбонатів та засвоюваних форм азоту протягом техногенного ґрунтогенезу в техноземах Нікопольського марганцеворудного басейну

У роботі показана можливість індикації регуляторних екосистемних сервісів протягом техногенного ґрунтогенезу за допомогою фітоіндикаційних оцінок вмісту карбонатів та засвоюваних форм азоту. Польові дослідження проводились протягом 2008–2017 рр. у дослідній біоекологічній станції Дніпровського аграрно-економічного університету (м. Покров, Дніпропетровська область, Україна). Полігони закладені у межах чотирьох типів техноземів: педоземи, дерново-літогенні ґрунти на лесоподібних суглинках, сіро-зелених глинах та червоно-бурих глинах. У роботі наведені свідчення того, що процеси накопичення карбонатів у техноземах мають безпосереднє відношення до іммобілізації атмосферного карбон диоксиду як зворотний механізм явищ парникового ефекту, що слід розглядати як важливий екосистемний сервіс антропогенних ґрунтів. Цей екосистемний сервіс саме молодих техногенних ґрунтів виконує значну позитивну функцію як фактор протидії парниковому ефекту та глобальним змінам клімату. Показано, що протягом ґрунтогенезу вміст засвоюваних форм азоту в техноземах демонструє динаміку збільшення з тенденцією до досягнення стаціонарного стану. Фактор субстрату є дуже важливим для перспективного визначення потенціальної родючості техноземів. У цьому контексті найкращі перспективи у лесоподібних суглинків та червоно-бурих глин, навіть порівняно з педоземами.
