Abstarct: Various methods are able to investigate the fracture process and the process of rock deformation. One of these methods due to its unique features is a widespread application in the field of fracture mechanics is an acoustic emission method. When the rock is placed under load with the rapid release of energy high frequency transient elastic waves emanate from an internal rock source called the acoustic emission phenomenon. The acoustic emission occurs due to the growth of microstructures, pore porosity, displacement levels of microstructure and granular displacement. This phenomenon is widely used in stone engineering for the monitoring sustainability of underground spaces oile and gas shafts and so on. In rock mechanics this phenomenon is used in the development of microcraks and rock injury and destruction. Each wave emanating from a rock source has five parameters (count, energy, rise time, duration, amplitude). The acoustic emission phenomenon , like the stress- strain curve, investigate the process of rock failure, so there is a close relationship between this phenomenon and the stress on the stone. In this study, we tried to investigate the relationship between each acoustic parameter and damage and stone failure. Tow samples stone of zeolite and granite were prepared for this purpose. Each of the samples was then subjected to single – axis and Brazilian tests with acoustic tests. After the data were taken, the diagram stress – time and diagrams of each of the acoustic parameters were plotted in time and then plotted in a three – axis gragh of time in order to investigate the relationship between each acoustic parameter with damage and stone failure. According to diagrams, it was concluded that the acoustic parameters have a weak activity in the early stages of loading, and at the stage of stone damage, the microstructure are combined and from large cracks, they are maximized and can be count, energy, and duration parameters were used to analyze damage and rise time and amplitud parameters for analysis of the acoustic emission source.
