Wastelands of the mining industry are among the largest of disturbed areas that demand revitalization. To reduce environmental impact and to better manage these geo-resources, the formation of sustainable plant and soil complexes and the restoration of self-recovery soil function are critical points. The successful return of vegetative cover at pos...

Insulation methods, helping to prevent the negative environmental impact of mine dumps, tailings and other waste storages, are considered and their drawbacks are revealed. The proposed two ways of environmentally sound and cost-effective preserving are described. The first approach is to form polymeric screens over the waste surface, as well as und...

The article presents an assessment of the technogenic impact on the atmospheric air inflicted by oil and gas extracting and processing facilities in Western Siberia. It is revealed that heterogeneity and areal dispersion of emission sources are the key features of the considered industry. Mathematical statistics techniques allowed grouping sources...

The article presents the data based on the long-term observations of the Lomonosov mine tailing storage impact on the natural environment. The study of the chemical, mineral and phase composition of waste, sampled at the tailing site, was carried out. It was determined that the ore beneficiation waste in the Lomonosov deposit is generally represent...

Hydrochemical monitoring of the tailing dumps area of the Apatite JSC established that the molybdenum content in drainage waters is tens of times higher than the maximum permissible concentration. A study of drainage and natural waters in the impact zone of the tailing facilities of concentrating mills demonstrated that the major share of molybdenu...

The paper provides an assessment of the potential technogenic impact of sulphide-containing wastes produced by ore extraction and processing at the Ozernoe deposit, which is currently at the initial stage of mining. The analysed averaged samples of ore and wastes of mining and processing were obtained in the course of semi-industrial experimental p...

The results of the «Mezhdurechye» coal-preparation plant moist waste coal studies are presented with a view to determine promising lines for waste coal recycling. The low heating value, ash content, main fuel elements' contents and cindery part contents were determined. It was revealed, that dumped waste coal contains approximately 60 % carbon. Was...

An evaluation of existing insulation and remediation technologies for solid mineral waste storages is carried out. Results of field observations at one of the largest tailings in Russia are given. A quality of atmospheric air, and surface and ground water are estimated in the impact areas of a magnetic separation waste storage at an iron ore deposi...

The growth of industry accompanied by the formation and accumulation of various wastes did not correspond to measures reducing their long-time negative environmental impact. According to world statistics, the needs of a modern man for one year are ensured by 20– 30 tons of various mineral resources. Only 2–3 % of this amount pass into the final pro...

An inevitable consequence of any mining industry is the natural balance in the environment. In this context, the design and construction of mining and processing enterprises is necessary to conduct ecological monitoring research. Significantly affected by exposed air, due to work and taking into the account the specifics of the company is thrown wi...

Numerous studies of technogenic massifs in mining regions have shown that mineral waste undergoes weathering and transforms into new crystalochemical phases under the influence of natural and man-made factors. This process promotes dispergation of toxic elements and their migration with ground waters. The topical character of research carried out i...

Production objects of the oil and gas complex are sources of complex and concentrated impact on the environment and on the atmosphere, in particular. There is a necessity for attraction of powerful software to assess the real level of air pollution in the impact area of dangerous production objects of oil and gas complex in the normal mode of opera...
