Ecological Systems and Devices Annotation << Back Environmental impact assessment of underground geotechnology Earth's atmosphere Galchenko Yu.P. Sabyanin G.V. Development is accompanied by the formation of ore deposits and emissions of toxic gases of different composition and anthropogenic mineral dust, the amount of which is directly proportional to the overall annual volume of mining and energy destruction of ores and rocks. The analysis of the patterns of formation of the gas and dust flows to the Earth’s atmosphere in underground. A new technique for the quantitative assessment of the environmental effects of the gas and dust pollution of the atmosphere. Environmental assessment of the state of the atmosphere is characterized by the index, defined as the sum of the relative change in the average concentrations of toxic gases and anthropogenic mineral dust, and its density, equal to the intensity of the change in the index within the zone industrial impact. Keywords: Earth’s atmosphere; underground mining; geotechnology; man-made pollutants; methods; condition index; density index. Contacts: Е-mail: schtrek@mail.ru Pp. 56-60.
