A. Bespalko (Bespal'ko) [et al.] // MATEC Web of Conferences. — 2016. — Vol. 79 : Information-Measuring Equipment and Technologies (IME&T 2016) : VII Scientific Conference with International Participation, May 25-28, 2016, Tomsk, Russia : [proceedings]. — [01039, 10 p.].
Аннотация: The paper presents a block diagram of the recorder of electromagnetic and acoustic signals. The recorder provides monitoring of electromagnetic and acoustic signals under changing stress-strain state of heterogeneous materials and rocks. The analog amplifier input sensitivity of electromagnetic signals in 4 channels is 10 [mu]V, that of the electromagnetic signal intensity is 10 [mu] and that of acoustic signals is 50 [mu]V. The operating frequency range of recording is (1±100) kHz. The averaging of electromagnetic and acoustic signal amplitudes is performed within 1 or 5 seconds. The data on electromagnetic and acoustic emission materials is recorded in digital format in the internal memory of the recorder. The recorder operates off-line within 7 days. Repeated testing of the recorder in natural conditions of the Tashtagol mine showed that the changes in the amplitude and frequency parameters of electromagnetic signals (EMC) indicate the structural damage in mines made of rocks which differ in their electrical properties. Measurements of the intensity of electromagnetic signals enable monitoring the changes in the stress-strain state of rocks during and after blasting and other geodynamic phenomena.
