“…However, it was also reported as high as 80 %-85 % due to geo-mining conditions in most of the reclaimed coalmine overburden dumps (Maiti and Saxena 1998). Excessive amount of coarse fragments limit the fine earth volume required for root proliferation, water-holding capacity, and long-term nutrient availability of plants (Mukhopadhyay et al 2013;. It also reduces with time in surface horizons due to weathering processes (Haering et al 1993;Johnson and Skousen 1995).…”

Reclaimed mined lands provide an excellent opportunity to sequester carbon and combat global warming. Carbon sequestration on reclaimed sites depend on age of reclamation, composition of species, geomining conditions (soil characteristics) and prevailing climate. The aims of the present study were to calculate carbon (C)-stock of biomass of 4 years old plantation (dominated by Albizia lebbeck, Dalbergia sissoo and Bambusa arundinacea), understorey vegetation and litter, soil organic carbon in reclaimed minesoil (RMS) and compare with reference forest site. Allometric equation was used for the estimation of biomass C stock and found 13.0 Mg C ha -1 (A lebbeck 7.8 Mg C ha -1 , D sissoo 3.5 Mg C ha -1 and B. arundincea 1.2 Mg C ha -1 ), while stock of understorey vegetation was 0.98 Mg C ha -1 . In RMS, C stock was 16.3 Mg C ha -1 , out of which inorganic C contributed 1.7 g kg -1 (8 % of total soil C), Coal C 8.7 g kg -1(43 % of total soil C) and biogenic C 9.8 g kg -1 (49 % of total soil C). Total C stock in reclaimed site was calculated as 30.3 Mg C ha -1 (equivalent to 111 Mg CO 2 ha -1 ). The study concluded that (i) coal C is responsible for overestimation of C stock in RMS (ii) Maximun C stock stored in aboveground biomass component and (iii) reclaimed mined lands will take approximately 17 years to reach the level of C stock of reference forest site in dry tropical climate.

“…A mine-soil quality index (SQI) has been used for a selection of tree species suitable for reclamation (Sinha et al, 2009;Mukhopadhyay et al, 2013). In a reclaimed coal mine spoil, SQI progressively increased with the age of reclamation.…”

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.

“…Reclamation of degraded areas does not necessarily mean restoring the soil to the previous natural conditions (Mukhopadhyay et al, 2013) and, in the case of areas impacted by coal mining, the recovery of soil physical properties tends to be slow, as shown by differences between treatments and the undisturbed natural soil (Reference Soil), especially in subsurface layers (Table 5). Even after 58 months of revegetation, it can be observed that the BD in the 0.00-0.10 m layer of the constructed soil is 7 to 14 % higher and the OC content is 45 to 60 % lower than in the reference soil surface layer.…”

“…A vital component in exploitation of mineral resources is recovery of areas that have been degraded by the mining process, especially in the case of surface mining, which has major impacts on soil and landscape (Yada et al, 2015) due to the removal of vegetation cover and layers of soil and underlying rocks (Mukhopadhyay et al, 2013), resulting in total change of the soil profile (Stumpf et al, 2014).…”

Studies addressing the potential of grass roots in improving the structural quality of constructed minesoils are not frequent in the literature, although they are essential for understanding the re-establishment of soil functions in the environment. The objective of this study was to quantify the root attributes of the species Urochloa humidicola, Panicum maximum, and Urochloa brizantha and relate them to the physical properties of a constructed minesoil in reclamation of an area degraded by coal mining. The study was performed in a field experiment in a coal mining area located in southern Brazil. Soil samples were collected, five years after experiment installation, to determine bulk density, macroporosity, distribution of water stable aggregates expressed in different size classes, mean weight diameter of water stable aggregates, and organic carbon content, as well as for chemical characterization. Root sampling was performed by the monolith method to a depth of 0.30 m. Results confirm the hypothesis that the root system of the perennial grasses studied positively contributes to recovery of the constructed minesoil in the 0.00-0.10 m layer after 58 months of revegetation. The higher percentage of large aggregates, higher bulk density, and lower macroporosity in the subsurface indicate the presence of degraded layers, negatively influencing the development of the grass root system. Urochloa brizantha exhibited the largest root matter in the surface layer, influencing the breakdown of the large and cohesive aggregates, transforming them into smaller crumbly aggregates. In the 0.10-0.20 m layer, Urochloa humidicola showed greater volume and root length in relation to other species; nevertheless, changes in soil physical properties were not observed, showing that the time span of the root growth of the species was not sufficient to provide improvements in the subsurface layers.
