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.
The growth of open pit mining will entail an increase in the volume of waste rock stored in dumps. The largest specific weight on the volume of extraction will have large quarries developing deep parts of deposits. The annual volume of waste rocks at some enterprises will reach 20-100 million m 3 in loose condition by 2000, which will require additional areas for dumps from 2 to 9 thousand hectares per year. ...
