We present the articles of the third issue of scientific journal "Mining Science and Technologyβ (Russia) for 2024:
The performed study allowed to develop a model of hyperbolic time-distance curve of GPR impulses reflected from a local feature located in a rock mass with an arbitrary number of layers. Practical application of the obtained results in studies aimed at automated determination of electrophysical properties of rocks and soils by hyperbolic time-distance curves will allow to create a database with up-to-date information on dielectric permittivity of rocks.

What are the specific characteristics of ground-penetrating radar (GPR) in permafrost, and how can its effectiveness be improved?
The most important parameters for electromagnetic wave propagation in a medium are the waveβs speed and specific attenuation. The propagation speed of electromagnetic waves generally depends on the relative permittivity, the relative permeability, and the frequency of the applied field. On the example of a permafrost zone rock mass containing a layer of unfrozen rocks, the effect of the thicknesses of rock layers and their relative dielectric permittivity on the apparent dielectric permittivity resulting from the calculation of the theoretical hyperbolic time-distance curve was shown. The conditions under which it is impossible to determine the presence of a layer of unfrozen rocks from a hyperbolic time-distance curve are also presented. The results obtained in the course of the study are of great importance for the development of methodological support of GPR for determining electrophysical properties of rocks, which will increase the reliability of the assessment of their physical and mechanical properties, especially in the area of permafrost occurrence. Practical application of the obtained results in studies aimed at automated determination of electrophysical properties of rocks and soils by hyperbolic time-distance curves will allow to create a database with up-to-date information on dielectric permittivity of rocks.
