POTENTIAL MANIFESTATIONS OF ROCK BURSTS DURING URF CONSTRUCTION AND METHODS OF THEIR PREVENTION

JOURNAL: 2022, 21, p. 70-77

ANNOTATION:

At great depths, the Yeniseiskiy section of the Nizhnekanskiy rock mass selected for the construction of an underground research facility (URF) may involve some areas of firm rocks with high internal stresses that may cause spontaneous rock bursts. The paper provides a qualitative description of the mechanism standing behind the rock burst process, the necessary and sufficient conditions for its occurrence and the conditions for its extinction. It considers some engineering methods dealing with rock bursts which may be applied given special requirements set out for the URF construction.

Keywords: strength, uniaxial compression, rock burst, unequal compression, rock outburst, dynamic manifestations of rock pressure, necessary and sufficient condition, changes in the strength properties, non-sorbable radionuclides, rock degradation, rock burst prevention, radioactive waste.
