Some Remarks on the Seismometric Experiments Taking into Account the Thickness of the Frozen Layer Soil
Methodical studies of seismic wave propagation remain relevant in the shallow seismology, since the accuracy of the results depends on the appropriate analysis of the data. Monitoring of the thickness of the frozen ground is necessary for many scientific objectives and applications. The thickness of the frozen soil affects the accuracy of seismo-acoustic data in mining, seismo-acoustic logging and geological surveys used to study the structure of the geological formations, coal-seam fractures, assessment of the geological environmental stress state and shallow tomography. While the effect of the soil temperature on the velocity of seismic waves has been investigated well the seismic waves attenuation affected by the thickness of the frozen Earth top layer needs to be investigated further. No sufficient data is available of the electrical properties of the frozen top layer of the Earth.
