The article describes the change in the elastic parameters of soils in the sides of a coal mine during the development of mechanical erosion processes in the marginal part of the Quaternary deposits under the influence of natural and climatic factors. According to the records of seismic vibrations on the profile of the ledge, the limits of the seasonal change in the dynamic modulus of elasticity during freezing of the surface layer of wet soil are determined. An increase of almost 3 times the dynamic Young's modulus is established. The presented results confirm the increase in the activity of natural destruction of soils of the edge part of the sides of the coal mine under the influence of seasonal climatic factors.
