The authors discuss assessment of deformation characteristics of load-bearing elements in room-and-pillar mining system and natural horizontal stresses. This method is based on solution of mixed-type inverse problems using a two-dimensional elastic model. Numerical calculations for a typical mine geometry using synthetic input data (relative displacements of mine void boundary points, recorded using mine survey techniques) have found the required data amount sufficient to ensure unambiguous solvability of inverse problem.
