Abstract: The process of rock failure under external pressure is of considerable interest for studying the geomaterial fracture mechanics. While failing, the sample generates acoustic signals, which are elastic waves caused by formation and growth of microcracks. These signals, known as acoustic emission, play a key role in monitoring and predicting the fracture processes of various scales.Acoustic emission signals are characterized by a number of parameters, such as their amplitude, duration, frequency, energy, which allow analyzing the dynamics of the fracture process. Depending on the conditions, the process can proceed at different rates, i.e. from quasi-static to dynamic fracture modes. Analysis of the acoustic emission signals helps not only to determine the failure stages, but also to better understand the mechanics of crack formation. The system for recording acoustic emission pulses developed at the Institute of Mining of the Far Eastern Branch of the Russian Academy of Sciences includes a hardware and software complex that provides highly sensitive signal detection, along with methods for processing and interpreting data, with the functionality of filtering, analyzing and identifying key pulse parameters, as well as determination of the individual event coordinates inside the sample being studied in laboratory conditions with specified parameters.
Keywords: acoustic emission, geodynamics, deformation methods, acoustic methods, waveform registration, primary converter, Fourier transform, methods of acoustic emission localization
