In mining areas, mining activities have a serious influence on land use transformation, which further determines different ecological responses (Zhang and others 2010). It is proved that the vegetation recovery following mining is slow and qualitatively inferior compared to regeneration following other land uses (Peterson and Heemskerk …
3.1. Underground Mining. Typical underground mining operations begin either by clearing a section along the hillside where the coal outcrops or by tunneling downward to reach subsurface coal (Skousen and Zipper, 2021).Room-and-pillar mines progress by excavating linear channels into the coal seam and connecting the channels …
The area of abandoned land in mining areas in China has reached 1.436 × 10 6 hm 2 since 2005 (Sanmiquel et al., 2018) and is growing at a rate of 0.2–0.33 hm 2 of subsidence land for every 10,000 t of coal mined out (Xiao et al., 2014b). Especially, mining subsidence and ponding (He et al., 2020; Zhao et al., 2020) is the most …
After coal mining, the water accumulation areas of mining subsidence land in some mining areas can reach more than 50% of the subsidence area (Xiao et al. 2013). In the subsidence areas, permanent ponding and swamps easily form in cultivated farmland, and crop production is reduced or even stopped, which seriously affects crop …
Dave Parry (DP): Our mining legacy requires consideration across large parts of the United Kingdom. In Great Britain alone, nearly 15% of land is deemed to be in a mining area. Many urban and industrial centres have been located close to heavily mined areas, with the ten largest urban areas each affected by mining to some degree.
Functional and phylogenetic methods guide the effective rehabilitation of mine land. •. The combination of species used for rehabilitation may be optimized …
It includes capping and sealing contaminated areas, planting vegetation, salvaging usable materials, and reclaiming land affected by mining activity. The first step in the reclamation process is to locate and secure the mine site, followed by submitting an environmental impact report detailing any potential impacts from the proposed operations.
Once mining in a specific area of the site is completed and the excavators have left, the disturbed area is assessed, and the earthworks crew gets ready to go to work. As part of the execution phase, the earthworks crew reprofiles the suitable subsoil material (which was selectively handled and placed during excavation), creating the final ...
Coal mining disturbed land is the main sources of land reclamation in China. With the rapid increase of economy and coal production, more and more land has been disturbed by construction and coal mining; thus, land reclamation has become highlights in the past 10 years, and China is boosting land reclamation in mining areas. …

AMS is dedicated to creating the best mining services available. Mining services that are efficient, and safe. There is no need for "shortcuts" in any area of the mining business, and this includes land rehabilitation after mining. After mining, the land must be rehabilitated in a manner that is safe and efficient, so t…
Across the US, mine reclamation – even when approved by state regulators – rarely returns land to pre-mining levels of wilderness or productivity, according to a decade of government reports compiled by …
Environmental regulations for coal mining usually focus on protecting the watershed, but there's also the often overlooked risk of the coal slide. ... devastating slides and reclaiming mined lands ...
In 2012, Dr Solomon Jiya, who teaches geography and mining at the Ibrahim Badamasi Babangida University in Niger State, and his colleague, Musa Haruna, studied the biophysical impacts of tin mining activities on the environment and the impacts on land cover and land use in Bukuru — an area with the same level of devastation as Ganawuri …
Learn how we protect open space and reclaim land after mining is complete. Discover the water around you in lakes and rivers, wetlands, oceans, and underground. ... Salt is extracted from rich deposits in Central New York. Mining occurs in every county in New York State except Bronx, Kings, New York, Queens and Richmond. ... wetlands, wildlife ...
Since 1978, more than 2.8 million acres of mined lands have been restored for wildlife areas and wetlands, recreation areas, economic development parks, farms, golf courses, and other uses beneficial to the local community. At all U.S. mining operations, detailed plans for how land will be restored after use must be approved by government …
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 …
On this basis, we extracted mining-dredging areas among BRI countries. Mining areas in 41 countries had a total of 11,377 polygons that add up to 24,234 km 2, accounting for 42.31% of the world's mining areas (Fig. 5). That said, mineral activities in the BRI are numerous compared with the world's landscape as a whole, and in turn, …
The extraction of underground ore body inevitably causes a large amount of land subsidence. Current reclamation technologies in China mainly focus on stable subsided land, which means most of the affected lands are submerged into water because of the high groundwater table in some areas, leading to the loss of soils and inefficient …
Topsoil is an essential component for land reclamation in mining areas. It is seriously damaged if it is not mined out separately without being contaminated, eroded and protected. Systematic handling and storage practices can protect topsoil while in storage and after it has been redistributed onto the regraded area. Impact of coal mining on topsoil quality …
He was here with biology professor Wally Smith to study the impact of the elk in the area. ... Mine #10." It's from an earlier mining operation, with underground mines burrowing deep into the earth. More …
Several deficiencies exist in the present evaluation of land reclamation quality in mining areas. These include the absence of an established set of evaluation index systems and standard acceptance criteria, as well as the use of traditional sampling techniques, which are costly and in efficiency, and time-consuming. Compared with the …
At Stanwell's Meandu Mine, we undertake progressive rehabilitation: the ongoing, staged restoration of areas disturbed during mining, rather than large-scale …

The coal mining activities in Piparwar started in 1990 in an area of about 1,120.25 hectares, and around 14 million tonnes of coal was extracted annually before mining activities finished in June 2020. After mining was shut down, the mining company, in accordance with India's mining laws, decided to reclaim the mined area.
In one instance, the DoI report found a mining company ignored approximate original contour and applied for a permit revision only after reclamation was largely complete, which state regulators granted. …
