Forecasting of mining and geological processes based on the analysis of the underground space of the Kupol deposit as a multicomponent system (Chukotka Autonomous Region, Anadyr district)

The underground space of the Kupol deposit is analyzed as a multicomponent system – rocks, water, microbiota, gases (including mine atmosphere) and supporting structures metal support shotcrete (as an additional type barring) also stowing materials. complex host rocks highly disintegrated due to active tectonic volcanic activity in Cretaceous period. thickness sub-permafrost reaches 250-300 m. In 2014, they were found contain cryopegs with abnormal mineralization pH, which led destruction supports caving formation. waters aquifer are chemically chloride-sulfate sodium-calcium 3-5 g/dm3. According microbiological analysis, anaerobic aerobic forms microorganisms, including micromycetes, bacteria actinomycetes. microorganisms accompanied by generation hydrogen sulfide carbon dioxide. main types corrosion chemical (sulfate dioxide), electrochemical biocorrosion considered. most hazardous associated functioning microbiota. Forecasting systematization mining geological processes carried out taking into account presence two zones depth below bottom sub-permafrost, where operations currently underdone. importance assessing environment predicting shown, can serve basis for creating developing specialized monitoring difficult engineering conditions under consideration.
