| Popis: |
The article studies geological and engineering conditions of the mineral deposits located in cryolithic zone. The demand to study and analyze geological and engineering conditions is justified by safety requirements established to development of the deposits. The article is focused on pebble-phosphate deposit located in Polar Urals. The geological and engineering conditions of this site fall within very severe category, which is connected with endogenetic and exogenic processes of its accumulation. It is the genesis of the deposit that generated the factors that complicate drilling-in conditions, included but not limited to weathering crusts with significant depths and discontinuity, frozen rock mass and its cavernous porosity. |
