We used a combination of greenhouse and field experiments to assess the potential role of a woody species, Ulmus pumila, in the restoration of degraded soils associated with coal-mining activities in the …
Treating peat with nutrient-rich ash significantly increases the content of different nutrients in the substrate. Such ash treatment promotes the revegetation of abandoned extracted peatlands. The aim of this study is to analyze the effect of wood ash (WA15 = 15 t ha−1 and WA10 = 10 t ha−1), oil shale ash (OSA8 = 8 t ha−1), and a …
The impact of surface mining on surface runoff was reviewed in articles published from 2009 to 2020 indexed in Science Direct, Scopus, Web of Science, and Scielo databases. Measurement methods, quantities, influencing factors and trends of surface runoff in mining areas are presented and research gaps, challenges, and …
At present, mine restoration and evaluation are still in the progression stage (Dávila et al., 2020).In the early period, policymakers and scientists from different countries were committed to how ecological engineering could contribute to the ecological restoration of mining areas (Festin et al., 2019; Miao & Marrs, 2000).Ecological restoration of …
The mine chosen for study offered an opportunity to analyse, in a relatively small area with the same history and environmental conditions, two 16-year-old successional series derived from a hybrid approach (Martínez Ruiz et al., 2001).Twelve dump slope sites that varied between 0 and 14 years old in 1994, were monitored …

Arbuscular mycorrhizal fungal inoculum and N 2 -fixing plants in ecological reclamation of arid mining areas: nutrient limitation of the moss biocrust microbiome. Yun Guo, Yinli Bi, Puning Li, Tao Liu, Li Xiao, Peter Christie ... Moss biocrust microbial community C and P limitations were observed in the five revegetation types, with lower ...
Mine dumps are concentrated areas where waste rocks and stripped soil are stacked, accounting for approximately 45.5 % of the land damaged by open-pit coal mining, and these areas are crucial for land reclamation and ecological restoration in mining areas (Cai et al., 2022).Currently, revegetation is widely acknowledged as an important and …
Mining alters the natural landscape and discharges large volumes of wastes that pose serious pollution hazards to the environment, to human health and to …
Revegetation of areas degraded by mining provides the main source of carbon entry into their soil–plant–microorganism systems, which stimulates microbial activity and favours the establishment of important functions in the soil, which can result in an increase in soil quality (Baião et al., 2021, Bartuška et al., 2015, Chae et al., 2017 ...
dominant revegetation species, and Medicago sativa was planted as a ground layer to prevent serious soil erosion. 2.2 Plot Design, Vegetation Survey, and Soil Sampling To assess the outcome of revegetation approaches in sub-sidence areas, the surveyed areas were divided into passive revegetation (PR) and active revegetation (AR) areas, and
Bauxite mining, a key aluminum production process, can cause environmental degradation, soil erosion, and biodiversity loss. Reclamation measures like reforestation and water management can restore balance. Red mud, a by-product of alumina production, can enhance soil fertility and plant growth in post-bauxite mining …
The yearly vegetation indicator such as vegetation cover and spectral index, in non- or pre-mining area is much higher and more stable compared to post-mining area. Mining disturbance can cause a rapid decline. The vegetation indicator will stay at a low level until vegetation is reestablished through rehabilitation works or natural recovery.
Secondly, the mining area has a history of over thirty years of coal extraction, providing rich data resources for studying the long-term effects of mining activities. Lastly, detailed historical mining and reclamation records provide accurate spatiotemporal references for this study. this research delves into the long-term impacts of different ...
Despite the urgent demand for sustainable mining, the revegetation and rehabilitation of areas degraded by mining activities remain challenging. Uncertainties about species selection, the management and control of alien invasive species and monitoring procedures require ongoing multidisciplinary research. Modern functional and …
It also revealed exploited areas used for mining were worse than unexploited areas. Results showed GDP provided a negative result, natural causes provided a positive result, but when combined suggest a negative influence overall, whereby a combination of anthropogenic and natural factors have degrading effects.
Mining activities can generally give rise to vegetation deterioration, soil erosion, geological hazards and environmental pollution, which restrict the sustainable development of mining areas [1,2,3].Mining areas are thus a typical vulnerable ecosystem [3,4].To recover and maintain sustainable ecosystems around mines, revegetation has …
However, the soil microbial C-, N- and P-cycling genes' abundance and their regulatory roles in mining revegetation systems remain unclear, especially at long-term time scales. ... China. The mining area has been characterized as having a temperate, semiarid continental monsoon climate. The average annual precipitation ranges from 428.2 to …
Extensive coal mining causes significant ecological and environmental impacts on the local ecosystem, especially on the terrestrial ecosystem. Mining activities induce the degradation of topsoil …
Mining plays a central role in the global economy, making a substantial contribution to export earnings. Nevertheless, implementing sustainable mining practices that prioritise environmental responsibility during extraction remains a major challenge. In response, governments around the world have instituted policies, with the primary aim of …
Obviously, larger-scale mining entails further accumulation of heavy metals, and situations in which the mining area expands gradually are not conducive to seed …
As presumed, the succession was similar to the general pattern of primary revegetation. The study area increased diversity of weed as primary vegetation which influenced the better growth of Trembesi. A total of 17 natural plants were recorded as pioneer weed as well as late colonizer. ... (Hg) in soil of agricultural area around gold …
The evaluation of mining-induced impacts on vegetation is beneficial to revegetation in mining areas; however, the impacts of ground deformation have seldom been systematically evaluated and ...
