Soil properties in the Arctic are insufficiently explored and documented, particularly extensive monitoring of soil water temperature over a period time. critical for understanding land surface atmosphere interactions considered key factors revegetation during mine reclamation. This study assessed how substrate topsoil influenced content at reclaimed diamond Northwest Territories Canada. Three ...

Fifteen AML sites ranging in age from 13 to 35 yr in Northern West Virginia were selected from three surface-mined coal beds (Pittsburgh, Freeport, and Kittanning) to evaluate plant invasion and establishment on disturbed sites. Three 10 m by 10 m plots were randomly located on each site, and cover, density, and stem diameter of all woody plant species were measured. Herbaceous and plant litter...

Arbuscular mycorrhizal fungi (AMF) technology of bioremediation becomes one of the most hotspots in the research on coal-mining subsidence land. This article based on amorpha fruiticosa planting in the mining subsidence of Shendong mining area as a study object, arbuscular mycorrhizal fungi was vaccinated on amorpha fruiticosa after different monitor time, respectively measures are used to anal...

The closure of surface mines is a complex framework characterized by extended reclamations post-mining sites towards an environmentally friendly and sustainable land-use system development with beneficial returns to society the economy. paper demonstrates critical mine problem, draws research questions, introduces IDEF0 (Integrated DEFinition Function) process modelling method as low-cost easy ...

Current EU policy will force a significant reduction of hard coal mines in the near future due to environmental restrictions. There are also numerous non-coal underground that be excavated next few years. Taking above into consideration, it is worth starting plan further steps terms reclamation these facilities. Within this manuscript, both recently used and novel approaches space have been rev...

Reclamation of used moulding and core sands is defined as a treatment of waste refractory materials allowing to recover at least one component of properties similar to the properties of the new component and to reuse it for casting moulds and core production. In traditional technologies of casting moulds and core production on the basis of high-silica sands with binding agent addition, the recl...

The oxidation of iron sulfides in mine wastes is the main cause of acidic, sulfate, and trace element-rich acid mine drainage (AMD). However, the suite of reactions that transform iron from one species to another is quite complex. A reasonable strategy for controlling AMD production is to identify and further slow the slowest, rate-determining step (RDS) in the overall process. This paper provi...

The Appalachian region of USA hosts diverse forests and abundant high-quality coal reserves. Surface mining methods are often used for coal extraction. Because common reclamation methods in past years have not restored forest vegetation, surface mining has created a diverse land base. Although some mined lands have been placed into managed uses, most have not. Little is known about the extent a...

Tropical forests are among the most diverse ecosystems in world, completed by huge biodiversity. An expansion natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices needed as an effort reclaim their function. This paper summarizes existing practice of coal mining, covering regulatory aspects reclama...

[1] Iron-hydroxysulfate minerals can be important hosts for metals such as lead, mercury, copper, zinc, silver, chromium, arsenic, and selenium and for radionuclides such as Ra. These mineral-bound contaminants are considered immobilized under oxic conditions. However, when anoxic conditions develop, the activities of sulfateor iron-reducing bacteria could result in mineral dissolution, releasi...
