Abstract
The authors comment on features of formulation and structure of input data for the inverse problems used in rock mechanics to estimate state and properties of natural and anthropogenic objects at various spatial scales. The article gives examples of using solutions of inverse problems in coal bed degassing monitoring, by data on changes of pressure in hydraulic props on the overlying bed, and in assessment of deformation parameters of inclusions, by data of uniaxial compression tests of artificial heterogeneous samples.
