Summary: | The Barents region hydrotechnical structures (HTS) as part of the bulk earth dams and levees tailings of mining
enterprises in terms of requirements of the responsible entities have been considered. The brief review of
emergencies and accidents of HTS with an analysis of their causes and geo-ecological consequences has been
fulfilled. The necessity and urgency of the application of modern techniques for comprehensive research and
monitoring of the HTS state have been shown: geo-fluid mechanics computer modeling, subsurface georadar
sensing, GPS geodetic measurements, optical and radar satellite imagery. Joint use of GPR and satellite imagery
in combination with traditional engineering-geological, hydro-geological and geodetic studies allows obtaining
a more complete picture of the HTS state taking into account local and regional geological and fluid dynamic
processes. The system structure of HTS complex researches which creates a scientific and technical basis for
researching the geologic-geophysical environment, shifts, deformations and power influence has been
developed. This allows to reveal the hidden filtration and deformation zones in HTS at early stages of their
formation and in due time to make the administrative decision on prevention and localization of any emergency.
Application of modern methods for HTS complex researches will allow to receive operational information on
their state, parametrical sizes of volume, angular and linear deformations and movements, intensity of natural
and technogenic influence. The obtained data have to be integrated in the "Database and Parameters" geoportal
by means of which their logical processing and comparison to standard and extreme values has to be carried out.
On this basis expert assessment of the current and expected state of HTS is carried out and the operating
decisions including on development, in case of need, of preventive and protective measures are made |
