Mineral extraction is closely connected with the processes of human impact on the environment in order to provide raw materials and their partial loss. With the total extraction of mineral resources exceeding 6.5bn tons, the total losses in the subsoil amount to 2.5bn tons: about 50bn tons of harmful substances are emitted into the atmosphere, more than 2bn m3 of polluted waste water is discharged into water bodies and more than 8bn tons of solid waste is stored on the surface of the earth. The scientific school of SPGGI is developing a set of measures to protect the environment from the harmful effects of technological processes in open-pit and underground coal mining, which today is a demanded natural energy resource, and in the future will become one of the main ones, as its supply can satisfy the needs of all industries for several hundred years.
One of the main sources of hazardous air pollution on the territories of mining and metallurgical and enrichment complexes and adjacent territories are dust-forming surfaces of dumps. As a result of wind erosion, fine fractions, which have a predominant impact on respiratory organs, are easily transported from the surface to long distances. The article proposes a method that reduces dust and dust transfer of fine materials, increases the biological productivity of dumps and their rapid reclamation.
One of the main sources of hazardous air pollution in the territories of mining, metallurgical and enrichment complexes and adjacent areas are dusty surfaces of bulk dumps. As a result of wind erosion fine-dispersed fractions are the most dangerous from the point of view of impact on respiratory organs, easily carried away from the surface for long distances. The method providing reduction of dust formation and dust transfer of fine-dispersed materials, increase of bioproductivity of bulk dumps and quick reclamation is offered. The results of tests of the protective coating for resistance to air flow and the results of bioproductivity of the treated surfaces of dumps are presented.
The Leningrad Region has very insignificant reserves of the main types of fuel and energy resources, represented mainly by wood, peat, oil shale and uranium, the development of deposits of which is not planned even in the long term for environmental reasons. However, the consistent introduction of new technologies for processing fuel and energy resources, the involvement of local resources in the fuel and energy balance, primarily wood, peat and shale fuels, and the creation on this basis of processing and energy-producing complexes of local type can ensure energy security and change both the economic and demographic situation in the Leningrad region.
One of the main sources of hazardous air pollution of the territories of mining, metallurgical and enrichment complexes and adjacent areas is the dusty surfaces of bulk dumps. As a result of wind erosion fine fractions, the most dangerous in terms of respiratory hazards, are easily carried away from the surface over long distances. A method ensuring a decrease in dust formation and dust transfer of fine materials, an increase in the bioproductivity of bulk dumps and fast reclamation is proposed. The results of tests of the protective coating for resistance to air flow and the results of bioproductivity of the treated surfaces of the dumps are given.
