Empiric kinematic and dynamic acoustic characteristic of different genotypes rocks and their strength properties interdependence have been consider. Due to the small amount of researching the acoustic quality factor and the strength of rocks interdependencies they receive special attention. It is shown that the smaller value of the acoustic Q-value corresponds to the smaller tensile strength of rock. They are connected with each other. It has been shown on the example of the limestone samples of different lengths the insignificant influence of the scale factor on the interdependence of the acoustic quality factor and residual strength. These dependencies can be used for non-destructive evaluation techniques of the rock strength and resources of underground structures.
