The Vorontsovskoye gold deposit is located in difficult engineering and geological conditions due to the presence of karsted carbonate rocks within the western and southern parts of the future open pit field. Studies of karst forms in the areas of eastern (depths of 20-110 m) and southern (depths of 20-90 m) sides of the open pit were carried out. The most widespread are cavities with sizes 4-6 and 8-10 m.
Within the East Urals region, a number of districts and areas have been identified according to the conditions of distribution of karsted carbonate rocks of the Lower and Middle Carboniferous. Technogenic activation of karst process along the railroad routes, in the areas of mining, in the areas of large water intakes is noted. The great urgency of studying karst territories during their development is emphasized.
