PHYSICAL MODELLING OF GEOMECHANICAL PROCESSES IN BLOCK-HIERARCHIAL MASSIFS BASED ON UNIFIED INTEGRATED SIMILARITY CONDITION
The paper presents the results of similarity criterion use analysis applied to modeling with equivalent materials. Modern approaches take into consideration gravity forces only. That is why acceleration “a” is substituted with free fall acceleration “g” when formulas for defining similarity criterion are made up. In real conditions it is necessary to consider tectonic, reaction forces of elastic deformation of massif elements as well as processes of converting elastic energy into other types of energy. Thus, dynamic tasks can be solved with the use of equivalent material selection based on unified integrated similarity condition. This condition is essential for selection of equivalent materials to model block-hierarchical massifs. The experiments have revealed a number of important dependences allowing to establish contact stress concentrations according to their hierarchy and parameters of contact zones when stoping wok is modeled.
