abstract = {The study presents research on the unusual appearance of purple-colored organic minerals, ravatite (phenanthrene) and freitalite (anthracene), occurring in the migrating front wall of a heating spot in the Bytom coal waste dump (Upper Silesia Coal Basin; Poland). These minerals are known to be sublimation products, but their formation mechanism remains unclear. Additional minor components are fluorene, dibenzothiophene, naphthothiophenes, dibenzofuran, and their alkyl-derivatives, and n-C17 – n-C20 alkanes. Temperatures were surprisingly low (30–60 °C on the surface) at the sampling sites, though such large amounts of Polycyclic Aromatic Hydrocarbons (PAHs) typically form in a burning environment where temperatures reach 800–1000 °C. The relatively low temperatures suggest that the primary mechanism of formation was not direct evaporation (desublimation) of phenanthrene and anthracene from coal-waste gases but that their occurrence may reflect a catalytical polymerization of ethylene on iron (III) chloride synthesized in a reaction between HCl and a common Fe mineral such as goethite. Subsequently, both minerals crystallized on the cold dump surface. High concentrations of phenanthrene and anthracene in self-heating products, testified by ravatite and freitalite, mean that self-heating of coal waste may significantly increase backgrounds of environmental pollution by PAHs. © 2023 Elsevier B.V.},

abstract = {The paper presents soil features and chemical composition in a self-heating coal-waste dump. The investigations were carried out in the Upper Silesian Coal Basin. A fire zone in which the soil temperature exceeded 50°C was selected for our study. Soil analyses were carried out for three grain sizes – d > 1 mm, 0.063 mm < d ≤ 1 mm, and d ≤ 0.063 mm – enabling identification of the diversity of the chemical composition in soil fractions. The highest concentration of heavy metals is represented by Mn (212–6972 mg kg-1), Zn (127–3283 mg kg-1), Pb (33.6–1344.7 mg kg-1), Cu (38.9–101.4 mg kg-1), and major elements by Fe (14;300–117;400 mg kg-1) and Ca (900–63;600 mg kg-1). Soil chemistry showed variations within individual studied sites. The soil reaction ranges from acidic (4.3 in KCl and 5.26 in H2O) to moderate alkaline (7.96 in H2O and 7.31 in KCl), whereas TOC ranges from 1.21% to 14.60% and TN from 0.023% to 0.291%. The distribution of n-alkanes clearly showed a low degree of transformation of organic matter and characteristic high values of Pr/Ph ratio for humic coals and coal waste in the region. Grains with diameters greater than 1 mm exhibited completely different features than those of fractions smaller than or equal to 1 mm. High organic carbon content (14.60) was detected in the samples along with PAHs. The influence of fire on the chemical composition of all samples was identified using geochemical indicators. PCA analysis showed that the values of the variables were more closely correlated in finer grains than in the coarsest fraction. © 2021 John Wiley & Sons, Ltd.},

abstract = {Many temporary and permanent reservoirs of water occur on or near coal-waste dumps in the Lower- and Upper Silesian Coal Basins (Poland). Little or nothing is known of the degree to which their water chemistry might reflect (i) reservoir type, i.e., whether permanent or temporary, (ii) level of coal-waste thermal activity, i.e., whether inactive or self-heating or burnt-out or (iii) region, i.e., whether the dumps are in Upper- or Lower Silesia. To provide some answers, concentrations of selected ions (NH4+; HCO3−; F−; Cl−; Br−; NO2−; NO3−; PO43−;SO42−) were determined by ion chromatography and of nineteen elements (Al; B; Ba; Ca; Cd; Cr; Cu; Fe; K; Li; Mg; Mn; Na; P; Pb; S; Si; Sr; Zn) by inductively coupled plasma mass spectrometry (ICP-MS). The data allow a number of the following observations. When permanent reservoirs are considered, there is a clear relationship between concentrations of ions and major and trace elements and dump thermal activity. The highest concentrations occur where the thermal activity is high as inorganic components are transformed into more water-soluble forms. As dump thermal activity shows a regional pattern, it follows also that elemental and ion concentrations in the dump waters show significant regional differences. In temporary reservoirs, concentrations of ions and major and trace elements are much lower and any correlations between components less significant than in the permanent reservoirs; these reservoirs exist for too short a time for any balance between coal waste- and water components to be established. © 2021, The Author(s).},

abstract = {This study provides potential insight between self-heating coal-waste dumps and related environmental pollution in southern Poland. Samples collected from dumps in the Upper Silesian Coal Basin were used to quantify released contents of organic- and inorganic pollutants, i.e., polycyclic aromatic hydrocarbons (PAHs) and trace elements (Pb; Cd; Cr; Cu; Zn; Ni; Hg; As). Elevated Hg concentrations (~100–1078 mg/kg) and Pb (~600–2000 mg/kg) attest to the evaporation of these metals from deeper parts of the dumps. The acidic pH levels (3.0–4.5) may help to mobilize these elements. Pearson's correlation coefficients for samples analyzed by AAS and ICP-MS indicate a similar origin for Cd, Zn, and As. Mostly 2- and 3-ring PAHs, especially anthracene in burnt soil, dominate in the samples. Chlorinated PAHs, thiophenol, pyridines, quinolines (and derivatives) in thermally-altered samples, and waste containing pyrolytic bitumen indicate coking conditions. The high levels of Hg, Pb, and Cd, and chlorinated PAHs and nitrogen heterocycles formed or enriched during self-heating in these dumps should be deemed a significant environmental hazard. Calculating the lifetime cancer risks due to PAHs and heavy metals accumulations in the dumps are substantial, and access to these dumps should be prohibited. © 2021 Elsevier B.V.},

abstract = {A self-heating intensity index (SHII) based on the highest (pixel max.) and lowest (pixel min.) values taken from satellite thermal maps of burning coal waste dumps are proposed. The index enables the classification of such fires in Ukrainian- and Polish coal waste dumps. Both in Ukraine and in Poland, varying thermal intensities during 1985–2019 are revealed, using the SHII and following thermal intensity threshold values, namely, extreme thermal activity (> 7), advanced (3–7), moderate (3–1.5), initial (1.5–1), no activity (< 1). The SHII shows decreasing thermal activity in the selected Ukrainian coal waste dumps during 2017–2019. It aids in reconstructing the thermal history of the dumps. Analysis of satellite images revealed a large number of burning coal waste dumps in the Donetsk Coal Basin (Ukraine) with high thermal activity. Such burning likely reflects large amounts of organic matter and sulphides in the dumped material subjected to self-heating and self-burning processes, lack of compaction of the coal waste and/or high methane contents. Comparison of SHII values calculated from satellite- and drone thermal-camera images were compared to show that SHII from drone thermal images have much higher values than those from satellite images; the former have better resolution. Thus, SHII from Landsat- and drone images should be used separately in dump heating studies. © 2020, The Author(s).},

Vegetation analysis involved the determination of species composition, life forms, and synecological affiliation. The mosaic diversity of the granulometric composition of the stored material and dynamically changing soil temperature had an impact on the character of vegetation. A specific type of flora, with various ecological requirements, was formed. Hemicryptophytes and apophytes predominated, especially in thermally active zones. The distribution of the range of vegetation due to changes in soil thermics was examined during three periods within a selected transect, in which three types of surfaces with varying soil thermics and smoldering fire directions were distinguished. Temperatures ranged from 9.9 to 139 °C at a depth of 20 cm and, simultaneously, from 3.1 to 69.0 °C on the surface. Total organic carbon content in all samples ranged from 1.7 to 7.6 and, simultaneously, from 3.1 to 4.5% in the active fire spots. The concentration of total nitrogen ranged from 0.023 to 0.29%. Soil reaction (pH) fluctuated between 5.8 and 8.0 (in H2O). The variability of the range of vegetation in time and space indicated the directions of movement of fire spots. The analysis showed that underground temperature has a significant impact on the distribution and species composition of plants growing on coal-waste dumps. © 2021 Elsevier Ltd},

abstract = {The indigenous societies of the Fann Mountains were and remain dependent on the resources of the natural environment. The present study aimed at investigating the relationship between mountain communities and the use of ecosystem services that are subject to change due to the influence of social, economic, and political conditions. The study made use of the concept of ecosystem services, which extends the scope of analyses of the socio-ecological system to the sphere of cultural relations. The application of this approach was crucial due to the dominance of juniper forests within the ecological system, given that the juniper, as a result of its connection with religion and local traditions, considered a key species for the mountain societies. The identified structure of the ecosystem services indicates the significance of the juniper in providing the indigenous community with services which, due to the economic situation of the society are characterised by greater value (wood; food; medicine) than cultural ecosystem services. Identification of ecosystem services taking into account the concept of cultural keystone species should be a starting point for the protection and restoration of juniper forest. The results of field and social studies have shown that the stable maintenance of juniper forests ensures the existence of key species as the most important ecosystem services, e.g. provisioning, regulation and maintenance and cultural, indicating the correct relations between the society and the protection of mountain areas. The obtained results showed that the inhabitants claim that juniper forests with the participation of Juniperus semiglobosa and Juniperus seravschanica are the main elements determining not only the functioning of mountain ecosystems, but also the communities living there. This approach is capable of ensuring inclusive management of the socio-ecological system of the Fann Mountains. © 2021 Elsevier B.V.},

This study aimed to present an analysis of environmental changes in terms of land use and changes in vegetation on self-heating coal-waste dumps of different ages. Spatial and temporal analyses of land relief and land cover in the area of the investigated coal-waste dumps were performed. The investigated areas differed in size, shape, management, and land cover. Thermally active zones were identified. The results showed that the species composition of the flora is diverse, but representatives of the Asteraceae family dominate on both dumps. The diversity of flora in the investigated dumps depends on the presence of mosaic-and microhabitats (often of an extreme nature) and the nature of the vegetation in the surroundings, which is manifested by the participation of socioecological groups of flora. The pace and dynamics of succession on burning coal-waste dumps depends on the stage of the fire, the topography, and the nature of the substrate. The investigated changes in the elements of the environment are important from the point of view of application research and monitoring of postindustrial areas, which may allow for the optimal management of postmining dumps. © 2020 by the authors.
