A Novel Study of Waveguide Propagation Rules of Coal Rock AE Signal: Effects of Waveguide Size and Installation Method on the Propagation Rules of Coal Rock AE Signal
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 t...
