The paper presents the typology of forms of disturbance of natural conditions and types of technological objects used in the development of mineral deposits of the cryolithozone by open-cut mining. The reasons for the formation of talik zones (reservoirs) of technogenic-natural genesis, accumulating useful components, as well as harmful chemical elements, artificially introduced into the rock massif during the development of placer gold deposits in the cryolithozone conditions are considered.
The paper shows the negative impact of water encroachment and degradation of the cryolithic zone on the changes in the engineering-geological conditions of the study area and the operation of linear structures. The reasons for the increased activity of the complex of engineering-geological and geocryological processes and phenomena are considered. Measures and ways of elimination of unacceptable deformations of linear structures are proposed.
