Abstract EN
Different types of rocks generate acoustic emission (AE) signals with various frequencies and amplitudes.
How to determine rock types by their AE characteristics in field monitoring is also useful to understand their mechanical behaviors.
Different types of rock specimens (granulite, granite, limestone, and siltstone) were subjected to uniaxial compression until failure, and their AE signals were recorded during their fracturing process.
The wavelet transform was used to decompose the AE signals, and the artificial neural network (ANN) was established to recognize the rock types and noise (artificial knock noise and electrical noise).
The results show that different rocks had different rupture features and AE characteristics.
The wavelet transform provided a powerful method to acquire the basic characteristics of the rock AE and the environmental noises, such as the energy spectrum and the peak frequency, and the ANN was proved to be a good method to recognize AE signals from different types of rocks and the environmental noises.
