Abstract. The study of factor of dynamic quality of loading with experimental verification of the rational mode in the processes of crushing on the basis of application regular physics of destruction is conducted. The experimental indexes of energy capacity of crushing at destruction of fragile and plastic breeds are set. Application of method of behind-limit deformation allowed to expect parameters for estimation degree of dynamic quality (or plasticity) of destruction of geomedium. On the example of vibration cheek crusher with inclined chamber of crushing application of the vybro-percussive high-frequency modes of loading is realized. Parameters and indexes of processes of crushing and growing shallow, differentiating by dynamic quality of loading, are confronted. The positive influencing of the promoted dynamic quality of loading in the modes of operations of vybro-cheek cruster and stream mill is experimentally confirmed.
Keywords: geological environment, dynamic quality of loading, closeness of energy, destruction, vybro-cheek crusher.
