The nature of changes of the parameters of microseismic emission signals (MSE) contains important information about the stage of the deformation process during the destruction of rocks under various types of loading, and can also give predictive estimates of the destruction of the massif. In this paper, the study of the MSE behavior is carried out signals under direct shear loading of samples from tuff sandstone, siltstone and clay crust weathering. The analysis of changes of the parameters of the MSE signals: the number, amplitude of acceleration and frequency at the pre-limit stage, the limit load and the post-peak stage of deformation is given.
