Abstract:

Coal mine spoil is widespread in US coal mining regions, and the potential long-term leaching of toxic metal(loid)s is a significant and underappreciated issue. This study aimed to determine the flux of contaminants from historic mine coal spoil at a field site located in Appalachian Ohio (USA) and link pore water composition and solid-phase composition to the weathering reaction stages within the soils. The overall mineralogical and microbial community composition indicates that despite very different soil formation pathways, soils developing on historic coal mine spoil and an undisturbed soil are currently dominated by similar mineral weathering reactions. Both soils contained pyrite coated with clays and secondary oxide minerals. However, mine spoil soil contained abundant residual coal, with abundant Fe- and Mn- (oxy)hydroxides. These secondary phases likely control and mitigate trace metal (Cu, Ni, and Zn) transport from the soils. While Mn was highly mobile in Mn-enriched soils, Fe and Al mobility may be more controlled by dissolved organic carbon dynamics than mineral abundance. There is also likely an underappreciated risk of Mn transport from coal mine spoil, and that mine spoil soils could become a major source of metals if local biogeochemical conditions change.

Abstract:

The recovery of the belowground microbial community structure and diversity that occurs in long-term coal mining reclamation is critical to reclamation success. However, long-term coal mining reclamation can take ~10–30 years. Therefore, finding an effective method for promoting coal mine soil restoration in the short-term is necessary to minimise reclamation time. This study investigated the response of soil bacterial communities to fertilisation along a chronosequence of short-term reclamation. Fertilised and unfertilised soils with three short-term reclamation stages were examined to characterise soil properties, as well as bacterial structure and diversity. Fertilisation promoted available nitrogen, phosphate, potassium, and soil organic matter, as well as benefits in bacterial community diversity across the three stages, with the most beneficial effects at 7 years. 16S rRNA sequencing data showed that the predominant phyla across all soils were Proteobacteria, Actinobacteria, Acidobacteria, Bacteroidetes, Chloroflexi, and Gemmatimonadetes. Abundance of each phylum was altered by reclamation time and fertilisation. Clustering and functional analysis indicated that the bacterial community structure in soils with a longer reclamation time was more similar to that in natural soils, suggesting that longer reclamation resulted in increased soil activity and bacterial community diversity, which is likely also true for fertilisation. Our results demonstrate that reclamation duration is the main driving force to recover soil properties and bacterial communities, and fertilisation could enhance the beneficial effects with longer reclamation duration. Therefore, short-term reclamation, combined with fertiliser, is a potential strategy to improve soil conditions in coal mine areas and shorten the recovery time of reclaimed soils.

Abstract:

Abandoned mine lands continue to serve as non-point sources of acid and metal contamination to water bodies long after mining operations have ended. Although soils formed from abandoned mine spoil can support forest vegetation, as observed throughout the Appalachian coal basin, the effects of vegetation on metal cycling in these regions remain poorly characterized. Iron (Fe) and manganese (Mn) biogeochemistry were examined at a former coal mine where deciduous trees grow on mine spoil deposited nearly a century ago. Forest vegetation growing on mine spoil effectively removed dissolved Mn from pore water; however, mineral weathering at a reaction front below the rooting zone resulted in high quantities of leached Mn. Iron was taken up in relatively low quantities by vegetation but was more readily mobilized by dissolved organic carbon produced in the surface soil. Dissolved Fe was low below the reaction front, suggesting that iron oxyhydroxide precipitation retains Fe within the system. These results indicate that mine spoil continues to produce Mn contamination, but vegetation can accumulate Mn and mitigate its leaching from shallow soils, potentially also decreasing Mn leaching from deeper soils by reducing infiltration. Vegetation had less impact on Fe mobility, which was retained as Fe oxides following oxidative weathering.

Abstract:

Soil enzymatic activities such as urease and invertase, were determined in areas polluted by Nesslers reagent colorimentric method and Mo-Phosphate colorimentric method in Yu Long coal mine, Shandong Province. The index of heavy metal pollution and the relationship between the activities of soil enzymes were analyzed. The results showed that the contents of heavy metals in contaminated soils were higher than those in unpolluted soils and the enzyme activities were decreased significantly with increasing contamination. The results of multivariate regression model test indicated that the elements of soil heavy metals have different influence on the soil enzymatic activities. It is feasible to use this index as a primary biochemical parameter to evaluate compound heavy metals pollution.

Abstract:

Abstract. Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj coalfield area, India. The physical, chemical, and biological parameters of the soils, and trace metals and PAHs (polycyclic aromatic hydrocarbons) in the soils were evaluated. Soil dehydrogenase (+79 %) and fluorescein (+32 %) activities were significantly higher in underground mine (UGM) soil, whereas peroxidase activity (+57 %) was higher in opencast mine (OCM) soil. Content of As, Be, Co, Cr, Cu, Mn, Ni, and Pb was significantly higher in OCM soil, whereas Cd was higher in UGM. In general, the PAHs contents were higher in UGM soils, probably due to the natural coal burning at these sites. The observed values for the above properties were converted into a unitless score (0–1.00) and the scores were integrated into an environmental soil quality index (ESQI). In the unscreened index (ESQI-1) all the soil parameters were included and the results showed that the quality of the soil was better for UGM (0.539) than the OCM (0.511) soils. Principal component analysis was employed to derive ESQI-2 and accordingly, total PAHs, loss on ignition, bulk density, Be, Co, Cr, Ni, Pb, and microbial quotient (respiration: microbial biomass ratio) were found to be the most critical properties. The ESQI-2 was also higher for soils near UGM (+10.1 %). The observed indicators and the ESQI results revealed that soil quality assessment for these coal mining soils is largely depended on soil PAHs and potentially toxic trace metals. The proposed ESQI may be further refined by incorporating specific parameters related to human exposure risks and exposure pathways.

Abstract:

Surface mining for coal has contributed to widespread deforestation and soil loss in coal mining regions around the world, and particularly in Appalachia, USA. Mined land reforestation is of interest in this and other regions where forests are the dominant pre-mining land use. This study evaluated mine soil development on surface-mined sites reforested according to the Forestry Reclamation Approach, representing a chronosequence of time ranging from 0 to 19 years after reclamation. Soils were sampled in depth increments to 50 cm and analyzed for a suite of soil physical and chemical characteristics. Overall, soil fines (silt + clay) tended to increase over time since reclamation (17% silt at year 0 increasing to 35% at year 11; 3.2% clay at year 0 increasing to 5.7% at year 14) while concentrations of metals (e.g., Al, Mg, Mn, Na) demonstrated varied relationships with time since reclamation. Concentrations of organic carbon (OC) tended to increase with time (0.9% OC at year 0 increasing to 2.3% at year 14), and were most enriched in near-surface soils. Some soil characteristics (e.g., Na, OC, Ca) demonstrated patterns of increasing similarity to the forest control, while others were distinct from the forest control throughout the chronosequence (e.g., Al, clay, Mn, gravel). Future surveys of these soils over time will elucidate longer-term patterns in soil development, and better characterize the time scales over which these soils might be expected to approximate forest soil conditions.

Abstract:

Abstract. Surface coal mining in the eastern USA disturbs hundreds of hectares of land every year and removes valuable and ecologically diverse eastern deciduous forests. Reclamation involves restoring the landscape to approximate original contour, replacing the topsoil, and revegetating the site with trees and herbaceous species to a designated post-mining land use. Re-establishing an ecosystem of ecological and economic value as well as restoring soil quality on disturbed sites are the goals of land reclamation, and microbial properties of mine soils can be indicators of restoration success. Reforestation plots were constructed in 2007 using weathered brown sandstone or unweathered gray sandstone as topsoil substitutes to evaluate tree growth and soil properties at Arch Coal's Birch River mine in West Virginia, USA. All plots were planted with 12 hardwood tree species and subplots were hydroseeded with a herbaceous seed mix and fertilizer. After 6 years, the average tree volume index was nearly 10 times greater for trees grown in brown (3853 cm3) compared to gray mine soils (407 cm3). Average pH of brown mine soils increased from 4.7 to 5.0, while gray mine soils declined from 7.9 to 7.0. Hydroseeding doubled tree volume index and ground cover on both mine soils. Hydroseeding doubled microbial biomass carbon (MBC) on brown mine soils (8.7 vs. 17.5 mg kg−1), but showed no effect on gray mine soils (13.3 vs. 12.8 mg kg−1). Hydroseeding also increased the ratio of MBC to soil organic C in both soils and more than tripled the ratio for potentially mineralizable nitrogen (PMN) to total N. Brown mine soils were a better growth medium than gray mine soils and hydroseeding was an important component of reclamation due to improved biochemical properties and microbial activity in mine soils.

Abstract:

Mining of coal (fossil fuel) resources in Enugu resulted in groundwater pollution/depletion and left the mine site with the potentials of air pollution, loss of landscape/aesthetic degradation and soil contamination. Other Environmental impacts were extensive soil damage, alteration in microbial communities and affecting vegetation leading to destruction of vast amounts of land and displacement of dwellers. Reclamation is the process to restore the ecological integrity of these disturbed mine land areas. It includes the management of all types of physical, chemical and biological disturbances of soils such as soil pH, fertility, microbial community and various soil nutrient cycles that makes the degraded land soil productive. Mining does not mean permanent loss of land for other use. On the other hand it holds potential for altered and improved use apart from restoring for agriculture, forestry and irrigation. This paper attempts to view the best practices for reclaiming the abandoned Enugu coal mine site which ceased production since 2002.

Abstract:

The article describes the change in the elastic parameters of soils in the sides of a coal mine during the development of mechanical erosion processes in the marginal part of the Quaternary deposits under the influence of natural and climatic factors. According to the records of seismic vibrations on the profile of the ledge, the limits of the seasonal change in the dynamic modulus of elasticity during freezing of the surface layer of wet soil are determined. An increase of almost 3 times the dynamic Young's modulus is established. The presented results confirm the increase in the activity of natural destruction of soils of the edge part of the sides of the coal mine under the influence of seasonal climatic factors.

Abstract:

Soil compaction impedes plant growth by negatively affecting water infiltration, soil aeration, access to soil water and nutrients, and consequently restricts root development. Previous studies to alleviate such problems in rehabilitated mine soils using a single amendment material did not provide a long lasting solution. The aim of the study was to quantify the role of different amendments in alleviating selected soil hydraulic properties. Five single amendment materials and three different blends of amendments were mixed thoroughly with degraded mine soil in a 1:3 (amendment:soil) ratio and packed in columns. Two additional unamended soils with different bulk densities were included as benchmarks. In general, the application of amendments reduced bulk density (BD) by 4–20%, enhanced infiltration rate by 15–70%, increased porosity by 5–35% and increased plant available water (PAW) by 9–33% compared with the unamended soils. Between amendments, the blends of amendments reduced BD by 9–16%, enhanced infiltration rate by 17–59%, increased porosity by 6–32%, and PAW by 4–28% compared with single amendments. The study showed that a blend of amendments have better soil restoration capacity through improving porosity, infiltration rate and plant available water. A blend of amendments therefore has the potential to be a sustainable and an important component of a rehabilitation strategy for surface coal mined soils.

Abstract:

Heavy metal concentrations of soils around two gangue hills from Zhuxiangzhuang coal mine, northern Anhui province, China had been determined by using X-Ray Fluorescence, and the calculation of enrich factor and index of geo-accumulation, as well as multivariate statistical analysis (including principle component analysis and cluster analysis) had been brought out to light: V, Cr, Fe, Cu and Zn of soils are unpolluted when normalize to soil environmental background value of China. However, when normalized to their minimum concentrations, Zn is light pollution. Two sources of heavy metals have been identified by using multivariate statistical analysis, including lithogenic (V and Fe) and anthropogenic (Cr, Cu and Zn). The soils from the area between two gauge hills have the highest degrees of heavy metals pollution relative to other areas, implying that the method in the Zhuxianzhuang coal mine is useful for environmental protection.

Abstract:

The concentration of heavy metals (Cr, Cu, Ni, Zn, Mn and Fe) were studied around coal mine spoil piles in Shiguai district of Baotou located in Inner Mongolia grassland and desert transition zone. Aim of the study is to control soil heavy metal pollution of coal mining area and provide the basic data information. The results indicated that concentrations of Cu, Cr, Ni and Zn in the soil along the roadsides were higher than other sampling areas. The pollution characteristic and the elements of heavy metal contamination were corresponding with the concentrations of the different types of coal mine spoils. According to the single factor pollution index, soils from different regions were contaminated by Cr, Cu, Ni, Zn, Mn and Fe in varying degree. The pollution degree was in order: Cu > Cr > Fe > Zn > Ni > Mn. Nemerow’s synthetical pollution index indicated that soils from the roadsides had the most serious heavy metal contamination, the index was 3.11. The order of pollution level in different regions was: roadsides > flood land > farmland > woodland. The health and stabilization of environmental quality are being threatened by soil heavy metals.

Abstract:

The national project “Ecology” sets to bring up to date the ecological policy of the environment-geared laws of the Russian Federation which must preserve biodiversity and afford the involvement of all participants in the process. Revegetation, as part of the program, sets to restore disturbed lands to a condition suitable for their use in the national economy and prevent their anthropogenic impact on the adjacent areas. The quality of reclamation works is not always at an adequate level, which creates difficulties in the remediated lands development. This is a consequence of insufficient information at the design stage, specifically data on the composition and properties of the soil cover and worked-out rock mass, lack of special technical support for the implementation of remediation measures at the proper level, the landscape of the deposit is not taken into account during the work with disturbed soils. Intensive use of the studied territories of the Sartakinsky, Karakansky and Mokhovsky fields both in agricultural and mining industries led to changes in the natural biocenos. This paper presents the study of soil-agrochemical characteristics (granulometric and structural structure of soil, the humus content, hydrogen index, the content of food elements, hydrolytic acidity, the sum of absorbed bases, absorption capacity, etc.) on different genetic horizons of zonal soils of Mokhovsky coal mine, and specifically unbroken soils of Mokhovsky, Sartakinsky and Karakansky fields on possibility of their use at carrying out of biological reclamation.

Abstract:

Soil organic carbon content [Corg], pHH2O, pHKCl and microbiological characteristics (microbial biomass carbon [CMB], extracellular microbial carbon [CEX], respiration, ammonification, and nitrification) were studied in 11 reclaimed soils, where the technical reclamation was carried out by Most Coal Mining Company in the year 2000 or 2001. These soils were immediately sown with legumes and grasses. Corg content in soil was rather wide ranging between 0.15–4.82%. The lowest value was determined in loess applied in the year 2001 at the locality No. 6 Mine Most, and the highest one at the locality No. 5 Mine Most amended with pulp wastes and sewage sludge (400 t and 200 t per hectare, respectively). pHKCl was in the range: 5.1–7.4. Six indicators of microbial status and metabolic activity of living micro-organisms, were used for the evaluation of the reclamation technology, i.e. (1) μg CMB/g dry soil, (2) μg CEX/mg CMB, (3) ratio CMB/Corg in per cent (4), potential respiration with glucose, (5) potential ammonification with peptone, (6) potential nitrification with (NH4)2SO4. The best results were found in the locality No. 5 Mine Most (reclaimed in 2000) amended with pulp wastes and sewage sludge (400 t and 200 t per hectare, respectively). The lowest values characterised the locality No. 1 Mine Slatenice (reclaimed in 2000) with a high content of coal powder and the lowest pHKCl (5.1). The use of mycorrhizal inoculum SYMBIVIT resulted in a high biological activity in the locality No. 11 Mine ___ that was the best among soils reclaimed in 2001.

Full text

Abstract:

Selection for aluminium (Al) tolerance was assessed by studying pollen-pistil interactions in Eucalyptus calophylla trees colonising a 30-year-old abandoned coal mine-site (soil pH 4.3) compared with E. calophylla trees on an adjacent forest-site (soil pH 5.3). Energy-dispersive X-ray micro-analysis of reproductive tissues demonstrated that low levels of Al occurred in the stigma, lower style and unfertilised ovules of forest-site flowers. In contrast, significantly higher levels of Al were detected in all reproductive tissues of mine-site flowers. Al concentrations were higher at the base of the style than in the stigma. Al was also detected in stigmatic exudates of mine-site flowers. Selection for Al tolerance occurred in the anther of mine-site flowers as pollen from mine-site flowers germinated six-fold (15.6%) compared with forest-site pollen (2.6%) at the highest concentration of Al (22 ppm) used. However, the rate of pollen tube growth was not significantly different between mine- and forest-sites at any Al concentration. Tolerance of Al by the mine-site pollen was not shared by the progeny as there was no increase in the survival or growth of mine-site seedlings in mine soils over forest-site seedlings. Controlled pollinations between mine-/forest-site pollen and mine-site pistils demonstrated that there was no significant difference in the number of mine- or forest-site pollen tubes at any level in the style in mine-site pistils. Pollen tube abnormalities principally occurred in mine-site pistils. We concluded that there is no evidence yet for a genetically-based tolerance of Al in E. calophylla on coal mining soils.

Abstract:

Topsoil is essential to abandoned mines and has to be stock-piled separately for post-mining land reclamation. If the storage period exceeds the 'shelf life' of the topsoil, it cannot be preserved by technical reclamation only. Opencast coal mining production in India is predicted to increase from the present level of 180 million tonnes per year to approximately 256 million tonnes per year by the year 2000. At that time about 60 km2 of land per year would be damaged by direct coal mines and 75 km2 per year would be affected by external overburden dumps and topsoil dumps. A large opencast coal mine was studied to evaluate the effect of stock-piling topsoil. Soil characteristics of soil dumps of six different ages (1, 3, 4, 6, 9 and 10 years old) were compared with those of surrounding unmined sites. Soil profiles were found to change greatly with age. Physico-chemical characteristics of soil dumps were found to deteriorate with respect to unmined soil. It was observed that, as the age of soil dumps increased from one to 10 years, the concentrations of suitable plant growth nutrients in soil gradually decreased and, after six years, the soils were found to be stagnant. This may be considered to be the 'shelf life' of topsoil. Biological reclamation must be adopted to preserve the topsoil if the storage period exceeds the shelf life period. The methodology provides guidelines for assessing the shelf life of topsoil in other areas.

Abstract:

Mining causes massive damage to landscape and biological components of an ecosystem. Due to extensive and unmanaged coal mining in the southern part of Nokrek Biosphere Reserve of Meghalaya, the area has been turned into degraded land since nutrient deficient sandy spoils are hostile for the growth and regeneration of plant communities. Soil is sandy to sandy loam and red, brown to dark brown in colour. The physico-chemical properties of the soil were greatly affected due to coal mining. There is an increased acidity i.e. from 6.00 in the undisturbed forest (control site) to 3.50 in the coal mine spoil since abandoned mine spoil discharge acidic water that are enriched with iron and other metals and metalloids. Apart from this, soil nutrients are greatly depleted. The core zone soils are rich in organic matter and nutrients whereas coalmine spoils show sign of degradation especially in the nutrient content.

Elevated salinity and sodicity are major challenges to reclamation of surface-mined coal sites in the Alberta Plains region. Research plots were established in 1981 at the Battle River Coal Mine near Forestburg, AB, to determine an optimum depth of subsoil replacement over sodic mine spoil required to sustain agricultural capability. Subsoil thickness was varied at 0, 25, 65, 135, 165 and 335 cm, overlain with 15 cm topsoil. The plots were monitored annually from 1982 to 1986 and were seeded to forage from 1987. Plots were resampled in 2013 to examine long-term changes in soil quality by comparing the results with the historical means for the 1980s. Key soil parameters measured are pH, electrical conductivity (EC), total dissolved salts (TDS), sodium adsorption ratio (SAR) and soluble Na. The soil quality of the root zone (0–40 cm) improved over time in all treatments as EC, TDS, SAR and concentration of Na decreased significantly between the 1980s and 2013. Amounts of EC and soluble Na consistently increased with depth, suggesting salt accumulation was predominantly by downward leaching, but with contribution by upward migration of Na from the underlying spoil. Relative to the native soils in 2013, the root zone quality ratings for EC and SAR in the topsoil/spoil treatment were better than in the shallow-bedrock Solonetzic soil. Ratings for the 25-cm subsoil treatment were also comparable with the local Chernozemic soil, but better than the fine till Solonetzic soil. This study demonstrates that a minimum of 25 cm subsoil and 15 cm topsoil are required for mitigating salinity and sodicity in these reconstructed soils. The resampling in 2013 demonstrates that long-term monitoring is essential to obtain a better understanding of reclamation outcomes.

Abstract:

Aim: To assess the ability of phosphorus to counteract harmful effects of heavy metals by reducing their concentration and increasing the maize yield. Methodology: Bulk surface soil sample (0-15 cm) was collected from heavy metal polluted soil of coal mine areas of Sutnga. Two pot experiments were conducted. Ten kg capacity pots were laid out for three phytoremediating crop and replicated 33 times. The processed soil was used for filling the pots. The first pot experiment was conducted to assess the phytoremediation efficiency of Helianthus annus and Vigna ungniculata on heavy metal polluted soil. Thereafter in the second pot experiment Zea mays L. was planted in pots maintained under experiment 1 and subsequently eleven levels of phosphorus i.e. 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 mg P kg-1 soil were super imposed in non-phytoremediated soil, phytoremediated soils through SSP. The elemental uptake and concentration of available phosphorus and heavy metal was determined.? Results: From the first pot culture experiment, it was observed that heavy metals content in soil after harvesting of phytoremediating crops reduced significantly in both the phytoremediated soils as compared to non-phytoremediated soil. From the second pot experiment it was observed that phosphorus as well as the heavy metals concentration and uptake in maize decreased significantly with increasing doses of phosphorus added in non phytoremediated soil.? Interpretation: This study clearly indicates that sunflower can be successfully grown as a phytoremediating crop in coal mine affected soils of Jaintia hills for phytoremediation of heavy metal polluted soils.

Full text

Abstract:

Data on the erodibility of overburden spoils resulting from open-cut coal mining are limited. These data are required to derive parameters for erosion prediction models which can be used in the design of re-formed landscapes after mining. In this study, laboratory rainfall simulation data were used to derive CREAMS (Chemicals, Runoff and Erosion from Agricultural Management Systems) interrill erodibility parameters K and nbov for Central Queensland coal mine overburden spoils. For the spoils studied, K values ranged from 0·0111 to 0·1398 Mg·ha·h/(ha·MJ·mm) and nbov values ranged from 0·0004 to 0·0081. Sediment yield was transport controlled. Results for 1 spoil, South Blackwater Terang, showed that total soil loss increased linearly with slope, and both K and nbov varied non-linearly with slope. If a constant set of K and nbov values is used in modelling, CREAMS over-predicts spoil loss for slopes greater than that for which the parameter values were determined, and under-predicts spoil loss for slopes less than that for which the parameter values were determined. The results show evidence of differences between mine spoils and agricultural soils, including modality of size distribution of surface sediment available for erosion, a higher percentage of dispersed clays in eroded sediment from mine spoils than from agricultural soils, and the observed amount of surface sealing and crust formation. These differences indicate that erosion{erodibility parameters for mine spoils should be measured and that agricultural soil parameters should not be a basis for estimates of mine spoil parameters.

In this work inductively coupled plasma - mass spectrometry (ICP-MS) method was used to determine content of harmful to human health heavy elements such as As, Cd, Cr, Pb, Th, U, and other essential elements Zn, Cu, Ni in soil samples collected around fence of two largest in Asia copper (Oyu Tolgoi) and coal (Tavan Tolgoi) deposits. The analyses revealed average content of arsenic in the examined soil samples is exceeding 1.4 times the maximum permissible limit. It is consistent with many previous studies emphasizing on a high occurrence of arsenic in soils, well waters of North and Central Mongolia. But the contents of copper in soil samples collected from three leeward locations of the copper mine Oyu Tolgoi are up to 2.18 times higher than the maximum permitted content established by the government standard of Mongolia. The contents of Cd, Ni, Pb, U, and Zn in soil probes collected from leeward locations of Ukhaa Khudag open pit mine of Tavan Tolgoi coal deposit are higher than that of in probes collected from the windward side of that by factor ranging from 1.34 to 1.64. These facts indicate possible transport and spread of heavy elements by wind from these intense operating open pit mines into adjacent dry and windy deserted region of Mongolia.

Abstract:

This paper describes the results of the study of the Mokhovsky coal mine undisturbed soils in different horizons of the soil profile. The study was conducted on the Sartakinskoe, Mokhovskoe and Karakanskoe fields. In each field the authors have determined the species composition of phytocenoses and soil types, and studied soil horizons and agrochemical characteristics (particle size and soil composition, humus content, hydrogen index, nutrient content, hydrolytic acidity, the amount of absorbed bases, absorption capacity, etc.). It has been established that the vegetation of the phytocenoses of the studied fields is represented by birch tree trunks with the inclusion of pine, sections of meadow and small fragments of steppe communities, where perennial herbaceous plants play a significant role, which is typical for temperate floras of the northern hemisphere. The results of the analysis of the structural and particle size distribution of the agrochemical characteristics of undisturbed soils in the Mokhovskoe, Sartakinskoe and Karakanskoe fields of the Mokhovsky coal mine indicate that these soils are of agronomic value, therefore it is recommended to remove and store the fertile layer from these sites with a view to their further use in biological reclamation to increase quality, productivity and environmental value of the restored lands in the Kemerovo Region. The fertile soil layer (PRP) and the potentially fertile soil layer (PRSP) from the Mokhovskoye field is recommended for forestry while the Sartakinskoe and Karakanskoe fields for agricultural restoration.

Abstract:

The discharge of highly mineralized mine waters of the Western Donbass negativelyaffected the Samara Bay area, which is of great fishery importance. Mine water storage pondswere built in deep erosional cuts in the territories of mine fields in the gullies of Kosminnaya,Taranova, Glinyana and Svidovok. The screening of the bottoms was not performed in any pond.The soils that make up the bottom are not aquicludes, which contributes to intensive filtration ofmine waters and pollution of aquifers. Artificial ponds built without waterproofing of bottoms,rock dumps, mine water discharge routes and other sources of pollution are actively involved inthe zone of influence of mine drainage and worsen the quality of drinking water, the reserves ofwhich in the Western Donbass are limited. There is flooding and flooding by groundwater, as wellas increasing (compared to the period before the violations) areas of land temporarily floodedduring floods on rivers in the valleys of the rivers Samara, Velyka Ternivka and such large beamsas Svydovok, Taranova, Kosminna due to subsidence of the earth’s surface. Differences in theconditions of formation of mine waters determine the nature and degree of their impact on theenvironment. The main difficulties making complicated accurate comparison between calculatedand field data in Samara river floodplain are following: a) changes in parameters of mining andpumping rates of water used for local needs; b) hydrological changes including formation ofnew channels, bed deformation; c) transformation of the monitoring network; d) increasing leakagethrough the clayey bottom of the ponds. The main objective is to provide a comprehensivegeo-ecological assessment of the state of the Samara river floodplain in the area of coal miningin the Western Donbass. Multispectral imagery of Sentinel-2 satellite system was used for remoteassessment within the study area. Geomorphologic assessment of the studied area was performedusing Sentinel-1 satellite radar interferometry. Flooding of the territory is observed due to minedrainage and subsidence of the earth’s surface. The risk of salinization of soils under the conditionsof water use from the beam “Glynyana” and from the Samara river is estimated as insignificant,from the beam “Kosminna” ‒ average. The SAR value of mine waters in “Taranova” and“Svydovok” beams corresponds to a high level of salinity. Samara river waters belong to the 3rdclass and are characterized as highly mineralized, sometimes unsuitable for irrigation. Intensivenatural overgrowth of the mine dumps that have passed the stage of mining reclamation has beenrecorded near the “Heroyiv of Space”, “Pavlogradska” and “Samarska” mines. The rate of selfgrowthof the land cover around the mine “Ternovska” and “Blagodatna” is estimated as average.The self-healing levels of the “Ternovska” and “Blagodatna West Donbasska” mines are ratedfrom low to high. The greatest risk of salinization of soils under conditions of use of water forirrigation is possible at a fence from artificial ponds located in Taranov’s and Svidovok’s beams.The conturs of “Verbsky”, “Ternivsky”, “Bogdanovsky” and “Boguslavskiy” piscicultural pondscan be corrected with map of remote sensing of Samara river floodplain geomorphology. The dataobtained can be useful during development of econetwork of promising ecological corridors inthe floodplain part of the Samara River as well..

Abstract:

Paper provides the results of research to determine the optimum technique of soil quality analysis in reclaimed land areas. The method involves topsoil stripping and mixed replacement techniques. The soils are sampled in different years after placement. Soil properties were analyzed. The data comes from the Wu-yang mine, Shanxi Province, China. Research has resulted in four conclusions: i) by topsoil stripping, soil fertility is nearly the same as the original soil, soil nutrients are higher in the tilth layer than in the bottom soil, and there is an upward tendency. ii) by mixed pushing, soil fertility is low and heterogeneous and needs to improve fertility. iii) changes of soil heavy metal concentrations are affected by dust and sewage and have little connection with reclaimed techniques and years after reclamation. iv) reclamation by topsoil stripping is better in the plain areas. Paper discusses how to choose the best reclamation technique and decide on the recovery time of land fertility.

Abstract:

A survey of soil and root samples collected beneath some pioneering plants colonizing reclaimed mine spoil at an opencast coal mine site at Chandrapur, Maharashtra State, India, was conducted in October 1994 to examine the possible host and edaphic influence on the occurrence of arbuscular mycorrhizal (AM) fungi. Thirteen plant species were sampled to determine the mycorrhizal root colonization and the number of spores of individual AM fungal species in the rhizosphere.Typical AM fungal infection was observed in roots of all the plant species examined. Mycorrhizal infection ranged from 20 to 95%. Sampled soils contained six spore-forming species of AM fungi (Acaulospora scrobiculata, Entrophospora colombiana, Glomus aggregatum, Glomus ambisporum, Scutellospora calospora and a previously undescribed species of Glomus). Fungal spore densities were not related to the mycorrhizal infection levels. E. colombiana and G. ambisporum were the leading species in terms of spore densities and frequencies. Phenotypic variations in spores of AM fungi were possibly related to the physical and chemical properties of the mine spoil.It is concluded that the pioneering plant species on mine spoils can cause the development of different populations of AM fungi. The study also indicates that certain species of AM fungi have broad environmental requirements.

Mosseler, A. and Major, J. E. 2014. Coppice growth responses of two North American willows in acidic clay soils on coal mine overburden. Can. J. Plant Sci. 94: 1269–1279. Acid-generating mine spoils with low pH are a major problem for revegetation and site reclamation. We compared growth responses of 15 genotypes from two widespread willow species, Salix discolor Muhl. (DIS) and S. eriocephala Michx. (ERI), native to eastern and central North America on two adjacent coal mine spoil sites that differed strongly in both pH (3.6 vs. 6.8) and soil texture. Despite significantly poorer growth responses for several coppice biomass traits on a highly acidic clay deposit compared with adjacent shale overburden, these willow clones demonstrated a surprising tolerance for extremely acidic soil conditions. Analysis of survival and growth uncovered genotype×environment interactions, indicating that both species and genotypic differences within species could be used to select better-adapted genotypes for extreme conditions. Most ERI and DIS clones grew comparatively better on the shale overburden site, but two of eight ERI clones and one of seven DIS clones grew significantly better on the acidic clay site, indicating the possibility for clonal selection for specific site adaptations within a species. Allometric relationships between coppice height and basal stem diameter were constant at both the species and site levels. However, there was a divergence of height and diameter in their relationship with green mass yields on the two different site types.

AbstractAmounts of mineral nutrients and aluminium (Al) were assessed in the globoid inclusions, proteinaceous matrix and druse crystals ofEucalyptus calophyllaseeds collected from trees grown in coal-mine (mean soil pH 4.3, Al 260 μg g−1) and forest soils (pH 5.3, Al 10 μg g−1). Energy-dispersive X-ray microanalysis (EDX) of bulk frozen hydrated samples indicated that significantly higher amounts of Mg, P, S, K and Ca occurred in the globoid inclusions of mine- than forest-site seeds. In both seedstocks, Al was detected in the globoid inclusions but not in the proteinaceous matrix or druse crystals. Significantly higher amounts of Al occurred in mine-site samples of dry and germinating seeds than in forest-site seeds. It was concluded that globoid inclusions may be useful as indicators of the soil conditions in which the parent plant was grown.

Abstract:

AbstractIn the Powidzki Landscape Park, there are 150 peatlands of a total area of 1,250.2 ha. On its edge, brown coal strip mines are in operation, causing deep land drainage that resulted in a drastic (up to 5 m) lowering of the water table in lakes and accelerated peatland disappearance. To determine the extent of the process, a comparison was made of the types of surface soil layers and their ash content in 20 peatlands determined in 1957–1965 and in 2017. They are located in the farmland lying the closest to the strip mine, Jóźwin IIB, and in woodland lying further away. The results were compared with those for a peatland in Skulsk, which was not affected by the negative impact of the strip mine. Fen peat, occurring there about 55 years ago has largely turned into grainy moorsh. In the 20–50 cm layer, an ash content has grown almost twofold, while in part of the peatlands organic soils have changed into mineral and organic-mineral ones. The greatest changes have occurred in the farmland. In all Park peatlands, grasslands have contracted threefold, while the area of forests and woodlands has grown fivefold. Today, about 10% of the peatland area is taken up by arable land of which there was none before.

Abstract:

The aim of this paper is to evaluate the effects of natural and synthetic zeolitic materials as soil amendments in contaminated soils. Two species of natural zeolites, clinoptilolite and mordenite, sampled from Samos Island, Greece, were used as low-cost modifiers (amendments). Both of these materials show perfect XRD-patterns. Moreover, coal fly ash (CFA) derived from the electrostatic precipitators of the Meliti power plant (Florina, Greece) converted via an alkaline hydrothermal treatment with 1M NaOH was used to produce a synthetic zeolitic material. The mineralogical composition of natural and synthetic zeolites was tested and identified by X-ray diffraction (XRD) and scanning electron microscope (SEM). The amendments and original contaminated soils from a former mining area of Lavrion, were mixed and equilibrated for 1 week, hydrated up to 40% of their water holding capacity. After the equilibration, the growth of Trifolium alexandrinum both in amended and original soils was studied in a pot experiment. The increase in pH value of treated soil by the tested amendments, confirmed the buffering effect and suggested the opportunity of using zeolitic materials for conditioning and remedying contaminated acidic soils from sulphidic mining areas. Moreover, the amended soils exhibited higher CEC values compared with unamended soil. Results showed that the synthetic zeolite produced by Meliti’s power station fly ash, was the most effective for plant growth, among the tested amendments. Between natural zeolitic materials from Samos Island, the most efficient was the clinoptilolite rich, probably because of its better water holding capacity compared with mordenite.

Short Communication: The potential of Sulfate Reducing Bacteria of ex-coal mine sediment pond as sulfate reducing agents of acid land in Samarinda, Indonesia. Bonorowo Wetlands 1: 79-82. The study aims to determine the effect of pH medium on the growth of sulfate reducing bacteria taken from the e-coal mine sediment pond and to determine its potential as a reducing sulphate agent of acid ex-coal mine land in Samarinda, East Kalimantan, Indonesia. Six SRB isolated from ex-coal mine sediment pond in Samarinda were used in this study. The SRB potency test in reducing sulfate was conducted by growing the SRB on Postgate liquid medium at different pH of 2, 4 and 6 by the addition of acid soils on each treatment. The results showed that sulfate reducing bacteria isolated from ex-coal mine sediment pond in Samarinda,, i.e., sp.1 (Desulfococcus sp.), sp.2 (Desulfotomaculum sp.), sp.3 (Desulfobacter sp.), sp.4 (Desulfobulbus sp. ), sp.5 (Desulfobacterium sp.) and sp.6 (Desulfotomaculum sp.) had potential as sulfate reducing agent of acid land. The efficiency of sulfate reduction was 89%, 91% and 91% in the pH of 2, 4 and 6, respectively. This indicated that the highest number of sulfate reduction is in the medium with pH 4 and pH 6. In addition, sp.5 (Desulfobacterium sp.) growing on medium at pH 4 had the best sulfate reduction efficiency (93%) compared with other SRB isolates.

Abstract:

Mining activities worldwide have resulted in soil nutrient loss, which pose risks to crop and environmental health. We investigated the effects of post-mine reclamation activities on soil physicochemical properties and microbial communities based on 16S rRNA sequencing and the further statistical analysis in the coal base in Peixian city, China. The results revealed significant differences in soil microbial relative abundance between reclamation and reference soils. Proteobacteria was the most abundant phyla in all seven mine sites regardless of reclamation age while considerable differences were found in microbial community structure at other levels among different sites. Notebly, Gammaproteobacteria, member of the phylum Proteobacteria, had relatively high abundance in most sites. Furthermore, Kendall’s tau-b correlation heatmap revealed that potentially toxic elements and other physicochemical properties play vital roles in microbial community composition.
