DESIGN RATIONALE FOR ENGINEERING MULTIPURPOSE BENCH FOR PHYSICAL SIMULATION OF GEOMECHANICAL PROCESSES IN SECONDARY STRESS FIELDS UNDER CONDITIONS OF MINING WITH CONVERGENT GEOTECHNOLOGIES

By way of experimental validation of general approaches to creation and design of a convergent mining technology, a set of theoretical research and virtual experiments is implemented using physical and numerical models with Map3D software. In mineral mining with convergent geotechnologies, for instance, when constructing frame-like or honeycomb geotechnical structures in rock mass, the stress state of the host rocks will change in the course of accessing, heading and stoping. The changes consist in the increase in the shearing stresses and, accordingly, in deformation of separate elements and whole structures. Thus, the level of the changes is to be determined at high reliability. The physical simulation methods currently in application in research work are reviewed. Considering defined advantages and disadvantages, a method is developed for physical modeling of natural-andtechnical systems using additive technologies and making physical models of rocks with regard to the theories of similarity and dimension. The case-study of the physical model and numerical model calibration in detection of damaged rock zones around mine openings and stopes is presented.
