Abstract
The mining and geological characteristics of the Veduginsky deposit and physico- mechanical rock properties are presented. The results of calculating the quality index of rocks of the Central and Southeast ore zones of the Veduginsky deposit are presented. A methodology for determining rock stability by Q -rating is given. The rock stability of the deposit is determined on the basis of Barton’s rating classification of rock mass stability developed at the Norwegian Geotechnical Institute.
