Abstract
Objective of the work: to study the state of the territory of Degtyarskiy area during the period of mining postexploitation and to study the methods for assessing and taking into account the current state of this object. Relevance of the topic. The postmining land area is the territory of mining development, including disturbed and under-worked land, where mining production is currently stopped and a certain amount of reclamation activities are implemented. According to numerous Ural’s data, hazardous geological processes are being activated in such land areas, so the Degtyarskiy section has been used as part of the state monitoring of the condition subsurface. The article presents the research methodology implemented over the past 10 years, and discusses the results obtained (as of 2019). Methods of investigation. For assessment of subsoil in Degtyarskiy phase, in addition to the analysis of the prior information, conducted periodic visits to the site from visual observations with photographic documentation, including remote shooting of the territory; bathymetric plots areas of the mine water output (quarry excavation) and dentinho target (Elchevsky pond-sump); serial sampling of water and bottom sediments in the control hydro sections; measurement of the hydrogen index of the aquatic environment at the site; laboratory testing of samples for specific components of specific chemical composition. The results of the work. According to obtained materials, dangerous level of the geochemical, hydro-and geodynamic disequilibrium is recorded at the Degtyarskiy post-exploitation site. It is proposed to continue periodic observations on the site as analog object, uncluding the works of both remode and geochemical nature in the mode at least once every five years. Conclusions. According to the set of indicators, the post-exploitation site is proposed to be classified as a dangerous natural and man-made object, so it is recommended to create registers and passports for all Ural’s postmining sites.

НАУКИ О ЗЕМЛЕНа территории Урала имеется более сотни участков постэксплуатации с эпизодическими сведениями по токсичным и опасным последствиям горного производства [9, 10].
Особую социальную актуальность имеют участки вблизи крупных населенных пунктов и городов, строительство которых сопровождало разработку рудных богатств Урала и других объектов социальноэкономической инфраструктуры
На Дегтярском участке постэксплуатации население города Дегтярска непосредственно находится в зоне воздействия горнопромышленного техногенеза, так же, как питьевой водоем города Екатеринбурга – Волчихинское водохранилище.

Опыт ведения ГМСН и его результаты, своего рода производственный эксперимент, полезны для использования и решения данной проблемы на других подобных объектах
