It is known that the process of freezing and thawing is always accompanied by the formation and change of stress and strain fields in the rock massif and the contacting objects of the environment.To assess the elastic-deformation properties of rocks, methods based on the study of seismic waves are often used, because the acoustic parameters are physically interrelated with the elastic and mechanical.The main part of the energy of seismic waves propagating from the place of explosion to the protected objects is concentrated in a relatively narrow range of frequency-amplitude spectrum of oscillations. Rock, unfrozen and cryogenic layers define these ranges, forming a certain waveguide in the massif.Soil freezing, at negative surface temperatures, varies from maximum to zero with a transition to positive temperatures at the appropriate depth. This process requires the establishment of a profile of changes in the velocity and energy of seismic waves depending on the depth, taking into account the temperature, humidity and cracking of the rock massif to ensure the stability of quarries and natural slopes.The depth of cryogenic layer formation and seismic wave velocity distribution are influenced by ambient temperature, humidity, mineralization and fracture massif, chemical and morphological composition of rocks, presence and height of snow cover, groundwater level, terrain, nature of vegetation, and other factors.

Integral and differential approaches to determining the volumetric compression of rocks caused by changes in the stress state are considered. Changes in the volume of the pore space of rocks are analyzed with an increase in its all-round compression. Estimation of changes in the compressibility coefficients of reservoirs due to the development of fields is an urgent problem, since the spread in the values of compressibility factors reduces the adequacy of estimates of changes in the physical properties and subsidence of the earth's surface of developed fields and underground gas storages. This parameter is key in assessing the geodynamic consequences of the long-term development of hydrocarbon deposits and the operation of underground gas storage facilities. Approaches to the assessment differ in the use of cumulative (integral) or local (differential) changes in porosity with a change in effective pressure. It is shown that the coefficient of volumetric compressibility of pores calculated by the integral approach significantly exceeds its value calculated by the differential approach, which is due to the accumulative nature of pore compression with an increase in effective pressure. It is shown that the differential approach more accurately determines the value of the pore compressibility coefficient, since it takes into account in more detail the features of the change in effective pressure.
