Title: Study of physical and chemical properties of edaphotopes of the waste dumps at coal mines in the Novovolynsk mining area Authors: Попович, Василь Васильович; Геник, Ярослав В'ячеславович; Волощишин, Андрій Ігорович; Сиса, Леонід Володимирович Abstract: Purpose. To define the influence of physical and chemical properties of edaphotopes that are formed at mine dumps within the Novovolynsk mining area (Ukraine) on the biogenic component of the region’s ecological safety. Methodology. The genetic horizons and the soils classification have been described according to the provisions of “Atlas of Soils”. Physico-chemical research on edaphotopes and soils within the horizons were conducted by the methods of N.B. Myakina and E.V.Arinushkina. The granulometric soil composition was determined by N.A.Kachinskii Method, with preparation by the pyrophosphate method; humus – by the Tyurin Method in the modification of Nikitin; pH of water and salt extracts – by the potentiometry method; hydrolytic acidity and the sum of imbibed bases – according to Kappen Method; degree of saturation with bases – by the calculation method; exchangeable calcium and magnesium – by the method of complexometry; easily hydrolyzable nitrogen – according to the Kornfield Method; mobile potassium – by the methods of Chirikov (non-carbonate samples) and Protasova (carbonate samples); mobile phosphorus – by the methods of Chirikov (non-carbonate samples) and Machigin (carbonate samples); СО2 of carbonates – by means of a calcimeter according to Geisler-Maksimyuk Method. The software included a package of application programs Surfer, MS Excel, MS Visio, Paint. The rock temperature was set using an HP-1300 pyrometer. Rock moisture was measured using a MG-44 moisture meter. The level of radiation background was measured with the use of “Soeks” environmental tester. Findings. During field studies in the Novovolynsk mining area, it was found that coal mine dumps are represented by three types of edaphotopes – rock (black) refuse, burnt (gray) rock and bulk soil mixtures. It has been established that the black burnt rock of the waste heap (light loamy soils) contains a significant amount of nitrogen, while the clay mass and middle loamy burnt rock has a very high content of easily hydrolyzable nitrogen (46.2 mg/100 g of rock). The study of burnt gray rock near the ignition sources at No. 9 Novovolynska mine showed that it is characterized by a high content of organic acids of unknown origin. The humus content in reclaimed soils is 0.45–4.52 %, and according to the humus gradation, they can be assigned to the group of soils with low humus content. The high acidity of the soil mixtures on the reclaimed waste heap at No. 2 Novovolynska mine suppresses the development of tree-shrubbery vegetation and slows its growth. Originality. It has been found that edaphotopes of waste dumps at coal mines of the Novovolynsk mining area are characterized by a low level of supply with organic substances, but high acidity. The patterns of changes in the temperature and humidity conditions of the waste dump have been determined, where the combustion processes are still observed. It has been proved that burning of dumps determines the change in the physical-chemical properties of the rock refuse and has a direct influence on the development of tree-shrubbery vegetation. Practical value. The established physical and chemical properties of edaphotopes, which are formed under the influence of temperature and humidity conditions at mine dumps within the Novovolynsk mining area, are recommended to be taken into account for substantiation of the choice of tree and shrub vegetation types when conducting the works on phytomelioration. The obtained data on temperature conditions should be taken into account when developing the plans to prevent spontaneous ignition and extinguishing of waste dumps, as well as in case of their further reclamation.

Title: FEATURES OF TEMPERATURE AND HUMIDITY CONDITIONS OF EXTINGUISHING WASTE HEAPS OF COAL MINES IN SPRING Authors: Волощишин, Андрій Ігорович; Попович, Василь Васильович Abstract: Burning of waste heaps of coal mines causes pollution of the environment with toxic gases, increases the temperature of the environment thereby changing the microclimate of the mining area. The purpose of the work is to investigate the temperature and humidity conditions of extinguishing heaps in the spring period in Novovolynsk mining area of Ukraine. The waste heap №1 of mine №9 "Novovolynska" mine were chosen for the research because the combustion processes were observed there in spring. The following actions are foreseen to implement this goal: to determine the temperature on the surface of the heap and in the places of combustion; to determine relative humidity indicators of the rock at a depth of 5 cm, 30 cm, and 50 cm; to measure the radiation background at the extinguishing heap. The temperature of the surface of the extinguishing heap was determined by the contactless pyrometer NR-1300. Humidity of the rock was measured with a moisture tester MG-44. The radiation background was measured by dosimeter by SOEKS USA, LLC. The software is a package of applications Surfer, MS Excel, MS Visio. Statistical data processing was performed using correlation analysis. It was found out that: the highest temperature regimes (+ 33-39 °C) was typical for the sites in combustion areas that are located on the middle tier of the southern slope exposure; at a depth of 5 cm the highest humidity was at the foot of the western side of the heap (44.8%); at a depth of 30 cm the highest humidity was at the foot of the western side of the heap (47%); at a depth of 50 cm, the highest humidity was at the foot of the northern side of the heap (55.1%); the highest rates of equivalent radiation dose were observed near the combustion sites of the rock and reached up to 0.18 μSv / h; the temperature on the surface of the extinguishing heap correlates with a humidity at a depth of 5 cm (K = -0.58542), 30 cm (K = -0.75665), 50 cm (K = -0.78303) and does not depend on the radiation background at all (K = 0.368116). With an increase in the rock temperature its moisture decreases and vice versa - at high humidity the temperature of the rock reduces. Extinguishing heaps are environmentally hazardous as they cause emissions of toxic substances to the environment that do not decrease over the years. Extinguishing heaps due to combustion processes cause the burning of the root system of plants, that leads to the complications of recultivation

Title: Physico-Chemical Properties of Soils in Lviv Volyn Coal Basin Area Authors: Попович, Василь Васильович; Степова, Катерина Вікторівна; Волощишин, Андрій Ігорович; Босак, Павло Володимирович Abstract: 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.
