- Abstract
Conditionally the process of stress-strain development of the medium begins with dislocation in crystals; then it runs with the formation of a zone of rock fracture and ends with the collapse of the massif (fracture under natural conditions). Each stage of the stress-strain development or the change is characterized by the specific value of the amplitude-frequency vibrations of the medium caused by this change. Massif response to the action of the deforming stress is manifested by a breakdown of the electrical connections in the crystal lattice. An assessment of modern means of personnel safety control and prevention of the state of the elements of local underground space (based on electrical and radio circuit diagrams that are not protected from electromagnetic interference) has been made. Significant disadvantages include their exposure to the human factor in the form of forced shutdown. Changes in the dipole moments in a covalent bond lead to the appearance of electromagnetic pulses, and the residual deformations in the form of dislocations create acoustic wave fields. The energy characteristic of three components of intermolecular interactions (orientation, inductive and dispersed) is given in the paper. Considering the nature of physical fields as derivatives of the deformations of the medium, which evolve over time into mechanical irreversible changes in the structure of rocks and the structural and tectonic formation of the massif, it is possible to establish a quantitative dependence of the intensity of these fields and the safety state of the developed massif. Fiber-optic sensors based on Bragg gratings are proposed as a basic technology for monitoring natural electromagnetic pulses and sound waves.
