Abstract
The failure concentration criterion has been approved in the laboratory tests of polymeric, composite and natural materials. It is of interest to check its applicability to larger scale objects, in particular, rocks, where prediction of catastrophic situation is a topical problem. In terms of a rockburst-hazardous mine in the area of Severouralsk town, based on the seismic event database collected by the local seismic service station for more than 30 years, the authors have analyzed the available information from the viewpoint of the concentration criterion of a destruction source formation. The paper illustrates workability of the criterion to revealing a rockburst source and predicting a strong rockburst in complex underground conditions
