The propagation of acoustic emission (AE) signal in waveguide is quite important for AE-based prediction of dynamic disasters in coal rocks. In this study, based on some relevant theories in wave mechanics, the elastic mechanical model of one-dimensional (1D) waveguide was firstly established, and the relationship between AE source signal and the signal at the waveguide’s receiving end was derived. On the basis of theoretical analysis, numerical simulation and laboratory test schemes were… CONTINUE READING
