The paper contains comparative analysis of solutions for problems with the rock-mass stress-strain state in the vicinity of a spherical cavity for the case of stationary and non-stationary temperature conditions. Such a cavity was created by blasting and further was used as storage for products that tend to self-heating. So, both problems considered the process inhomogeneity of the rock mass soil and the inhomogeneity caused by an action of various high-temperature fields. The results obtained prove the significant impact of the inhomogeneity on the stress state of the rock mass for any types of temperature conditions. The development of methods for calculation of underground structures that would fully consider the conditions of their creation and operation as well as actual properties of materials is one of crucial areas in structural mechanics.
