Such studies would assist in informing ecological restoration of these degraded sites. Here, a chronosequence approach was used to investigate early-stage primary succession on overburden spoil wastes derived from coal mining in a tropical climate over a 64-month period.
20 Due to the withdrawal of coal from power generation in the EU, mining companies in Poland are forced to adapt their production to the decreasing demand. Forecasting the volume of demand plays an important role in planning the volume of the mine's output. The demand for coal is constantly changing, with a downward trend. This article presents a method that allows to assess the impact of …
12%The biodegradation of coal discard is being intensively studied in South Africa in an effort to develop passive methods for the successful revegetation and rehabilitation of waste dumps, to mitigate pollution, and facilitate mine closure. Bacteria were isolated from slurries of coal tailings and diesel-contaminated soil, screened for coal biodegradation competence, …
These results indicated that land subsidence induced by coal mining caused losses in surface soil water and nutrients, and ultimately led to soil quality degradation. Therefore, the reclamation of mining subsidence land might be necessary, especially in arid and semi-arid areas.

Mountaintop coal mining is a type of surface mining that removes mountaintops to expose coal seams and discards the overburden in adjacent "valley fills." Valley fills occur in steep terrain where there are limited disposal alternatives. Abandoned mine lands are degraded lands and waters that are inadequately reclaimed after surface coal mining ...
Ecological restoration of coal mine degraded soils across arid and semi-arid environments worldwide remains particularly challenging. 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 northwest China.
The coal mines of Coal India Limited (CIL) removed about 500 million cubic m (Mcum) of overburden (OB) to produce 260 mt of coal in 2003-04 at an average stripping ratio of 1.92 cu m of OB against per tonne of coal production [4]. As demand for coal increases to meet the country's energy requirement, the coal companies are
on Ecological Restoration of Coal Mine Degraded Lands. The Society for Ecological Restoration (SER 2004) defines ecological restoration as 'the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed'. The process of natural succession, which happens concurrently with ecosystem development takes time.
For hundreds of years, the mine was a lifeline for residents in Beijing – more than 30 percent of the coal used in Beijing came from Datai coal mine before the mine was closed in 2019. In the late 1990s, the mine started to provide coal for overseas markets. …
The problem of acid mine drainage is sustained and amplified by continued increase in coal mining activities in different parts of the world. All this suggests the necessity of restoration of the degraded mined environment.
As mine technologies are developed to make it more profitable to mine low grade ore, even more waste will be generated in the future. Waste from the Mining Process Ore is mineralized rock containing a valued metal such as gold or copper, or other mineral substance such as coal.

The localised environmental problems that coal mining in the MPE will cause are well-documented and acknowledged by the mine's supporters. The mine's social and labour plan (SLP) notes that coal mining will generate dust, noxious gases and smoke, noise, vibrations, traffic, and the "contamination of surface and groundwater on downstream water users".
Loss or degradation of groundwater - Since coal seams are often serve as underground aquifers, removal of coal beds may result in drastic changes in hydrology after mining has been completed. Radical disturbance of 8.4 million acres of farmland, rangeland, and forests, most of which has not been reclaimed -- See The footprint of coal
Therefore, the objective of this work was to characterize the chemical features and to evaluate the soil microbiological attributes in areas degraded by coal mining and under recovery using bracatinga as cover plant.
Surface coal mining involves: removing parts or all of mountaintops to expose buried seams of coal, and. "interburden" (rock between coal seams). Overburden and interburden are disposed of in adjacent valleys because the broken rock will not all fit back into the mining pit, and disposal alternatives are limited.
