Influence of processes of hypergenic metamorphization of technogenic massifs on the degree of their environmental danger for the environment

Article preview

The author studied different technogenic massifs of various geneses containing sulphide sulphur and the research results have shown that under the influence of natural and man-caused factors mineral waste is subjected to weathering processes and transformation into new crystalchemical phases, which facilitates dispersion of toxic elements and their migration with ground waters. Studies help to establish that acid rock drainage formation and migration of pollutants is determined by physical and chemical metamorphization processes in infiltration waters. Ecological hazards from sulphide-bearing rock massifs are most adequately estimated with application of the acid indexing express-method.

Integrated monitoring of the impact of Severonickel Combine on the natural environment

Article preview

The research presented at paper carried out in area of Monchegorsk and directed on definition of mechanisms and an estimation of infringement and pollution level of an environment during industrial activity of factory «Severonikel». Results of research of transformation degree and migration probability of polluting components from waste on the open area solid wastes storage due to hypergenic processes are presented. Тhe high acid potential of solid wastes is proved and it at rather small volumes infiltration waters causes significant damage to the superficial waters because of global issue. Damaged water is an unique source of drinking water supply in area of Monchegorsk. Also in work the system of monitoring and an estimation of a soil-vegetative cover condition in forest ecosystems impacted by factory «Severonikel» is offered.

Socio-economic development of coal-mining regions based on the assessment of environmental capacity of the natural environment

Article preview

The results of the analysis of the environmental situation in coal-mining regions based on the assessment of the environmental capacity of the natural environment and its exhaustiveness are presented. The limiting level of coal mining within a typical administrative district in terms of area and population, providing environmental stability under the current normative indicators and applied methods and means of engineering environmental protection, is determined. A set of tasks, the solution of which at the level of the federal center by executive and legislative authorities of a particular sub-unit of the federation, or directly by the economic entities themselves will lead to a reduction in the negative impact of the coal mining industry on the environment and the health of the population of the region, is proposed.

Environmental and geochemical features of slag dumps transformation in the acidification zone

Article preview

The conducted studies prove the necessity to increase the hazard class of waste from the pyrometallurgical processing of Severonickel enterprise due to erosion and hypergenic processes, which cause water pollution with toxic metals and sharp decrease in pH level. Formation of acidic waters leads to transformation of the composition of cover sediments, surface and ground waters, as well as to increase of migration ability of polluting elements. Criterion dependences of transformation of mineral and chemical composition of mining and metallurgical wastes are established. The ways to reduce the technogenic load on the soil and vegetation cover and natural waters in the acidification zones are proposed: construction of a geochemical barrier for old, already stockpiled waste and change of the enterprise technology at the stage of slag formation and transportation.

Assessment of the negative impact of acidic water on the components of the natural environment in the impact zone of OAO Severonickel

Article preview

The main sources of acidic water formation are industrial effluents, slag dump effluents and gas emissions containing nitrogen oxides and sulfur dioxide. Taking into account hypergenic and erosion processes, it is necessary to increase the hazard class of these wastes. The results of laboratory analyses of waste samples causing negative acid impact are presented.

Methods to reduce acidification of groundwater and surface water

Article preview

The technogenic load of the mining and processing industry enterprise causing pollution of water resources is assessed. The analysis of samples taken at the technogenic massif on a scanning electron microscope, as well as laboratory analysis according to the European standard using an atomic absorption spectrometer, which allowed to determine the processes of formation of halos and flows of pollution, the intensity of the technogenic load in the area of sulfide waste storage was carried out. A methodology for assessing the environmental hazard of technogenic massifs was created and a method of economically feasible and safe waste storage was developed.

Assessment of the risk of acidic water formation in the impact areas of mining and metallurgical enterprises

Article preview

The technogenic load of enterprises of mining and mining and processing industries causing pollution of land and water resources and atmospheric air is assessed. Mining enterprises account for up to 80 percent of the volume of stockpiled wastes of all production complexes. Development of methods to assess the risk of impact of technogenic arrays on the environment is a very urgent problem, since it allows preventing or reducing the negative impact of technogenic arrays by targeted selection of the type and design of storage facilities for projected and existing enterprises, development of a set of measures to improve and rehabilitate disturbed lands. The analysis of landscape-geochemical situation formed under the influence of intensive technogenic load in the areas of waste storing was carried out, the processes of formation of halos and pollution flows were studied; the method of ecological hazard assessment of technogenic massifs was created, the method of economically expedient and safe storing of waste was developed.
