Abstract. In the article, the prospects for the use of load-bearing armored shells are discussed, which create the possibility of their application in the arising zones of stress concentrators, increased fracturing or zonal disintegration (ZDI) for the formation of objects of special-purpose or with special characteristics. This increases the resistance of the rock mass due to the use of special materials with certain properties (hydrophobic additives, etc.), which in total makes it possible to create formations for various purposes and with specified parameters.
Technical problems in the construction of underground structures are mainly caused by the need for the creation and subsequent operation of the internal space. For example, in relation to solving the problems of underground construction of special structures, construction of underground gas storage facilities (UGS), underground construction of protective structures (bomb shelters), construction of earthquake-resisting structures and buildings. The main problems of underground construction, its technical capabilities and solutions are considered. The possibility of using the worked-out underground space of mines is shown in connection with the problems of construction of underground protective structures (bomb shelters), underground gas storages. The possibility of using the phenomenon of zonal disintegration (ZDI) as the main economic prerequisite for the construction of earthquake-resisting buildings and structures in regions with earthquake-resisting mining and geological conditions is proposed, and schematic diagrams of technological solutions are given. The tasks are considered, the solution of which is of paramount importance for the problems listed above. The prospects for the application of technologies for the formation of load-bearing armored shells (LBAS) in conditions of zonal disintegration (ZDI) are shown, namely: control and forecasting of the occurrence of the phenomenon of the rocks ZDI in the course of various underground construction works; control of the state of the massif in which the LBAS are constructed to ensure the specified operating parameters; the use of the fracture zone between the rings of disintegration for filling with materials with certain properties (hydrophobic impurities, etc.), which ultimately makes it possible to create formations for various purposes and with specified parameters.
Keywords: armo-bearing shells, stress concentrators, zonal disintegration, underground gas storage, earthquake-resistive mining and geological conditions.
