The authors have experimentally established and substantiated the relation between the ultimate compression strength and the low-temperature induced acoustic emission in the compressed hard rock specimens, averaged in a preset temparature range. This relation shows itself most clearly if data sampling is subjected to pre-censoring by withdrawal of data obtained on specimens with abormal defectiveness detected from the analysis of the thermally induced acoustic emission. The study case of the ultimate strength evaluation for Kapustinsky granite by using the thermoacoustic emission measurements is reported.
