Designing mine workings, mining, construction of underground facilities for various purposes at great depths and in difficult mining and geological conditions is closely related to the task of determining the stress-strain state (DS) of rock massifs.
Fracture of rocks for industrial or other needs (hammering, drilling, extraction of piece rock, processing, etc.) regardless of the method and technology of loading is a local short-term intensive impact, proceeding according to the scheme: load application - deformation - growth of micro- and then macro-damages - growth of cracks - fracture. In this regard, the applied theory of rock failure should not take into account rheology and relaxation, i.e., the model of such failure does not take into account the evolution of micro- and macro-damages in the rock. These phenomena can be accounted for by the ultimate stress or strain in the current state of the fractured rock volume.
During the testing and industrial development of the process of charging wells with aquatools, a number of problems affecting the quality of explosive preparation of rock mass arose.
