The article reports electromagnetic emission (EME) measurements in rocks using REMI-2 equipment and recording–diagnosing system RDS REMI-3 developed jointly at the Institute of Mining and Novosibirsk State Technical University. REMI-2 measures EME signal strength and displays the results digitally. RDS REMI-3 is advantageous over earlier designed equipment as it downloads measurement data in the embedded memory. The EME records are displayed as oscillograms to enable detecting initial stage of rock failure based on analysis of change in structure, parameters and spectrum-and-time behavior of EME signals.
