Abstract
In this paper a research looking for to extend the acoustic emission (AE) technique from the evaluation of stress state of rock samples to know its composition is presented. For this purpose the rock samples were simulated by a composite made of a resin and borosilicate spheres. The epoxy resin playing the role of country rock and Borosilicate spheres represent the coarse grain. These samples were undergone to uniaxial compression test and the AE signals were recorded and studied looking for the identification of each material characteristic spectrum. The spectral analysis of these recorded signals shown that it is possible to identify the characteristic spectra of each material from the full spectra of composite.
