The adversities of geology and permafrost hydrogeology in operating roadways under conditions of increasing depth of mining in the Kupol deposit are formulated. It is emphasized that safety of mining will depend on endogenous and exogenous processes. The article presents the systematization of geological processes by the criterion of their hazard for two zones of the Kupol deposit: the upper zone of permafrost rocks and the lower zone of thawed rocks. The importance of taking into account the biocorrosion processes induced by the activity of various microorganisms—cryophiles, mesophilic micromycetes tolerant to low temperatures and some anaerobic bacteria—is for the first time highlighted. The geological processes systematization for the Kupol deposit has been accomplished for the first time ever.
