Under consideration is the process for evaluation of rheological properties of construction components in the underground chamber-and-pillar system to mine solid mineral reserves. The process is based on solving the inverse mixed-type problems in terms of a 2D viscoelastic geomedium model. Feasibility is demonstrated to evaluate in-situ state parameters characterizing rheological deformation of rocks. Numerical experiments with the use of synthetic input data (viz. relative displacements of the worked-out space contour points recorded by underground geodesic monitoring) for the prescribed absolute precision of the instruments made it possible to establish a required population of measurement data to provide an inverse problem-solving procedure.
