Methodological aspects of studying karst in the exploration of the Vorontsovskoye gold ore deposit in the Northern Urals, to be developed by open-pit mining

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.
