Abstract
A method is developed of interpreting the measurement data of the variations of displacements and deformations on the free surfaces caused by carrying out mining works. It allows us to quantitatively estimate the horizontal components of the natural stress fields and elastic characteristics of the constructive elements of the excavation technologies of solid mineral deposits. The method is based on the solution of inverse problems for the system of elasticity equations in the domains of an arbitrary shape. The structure of the proposed target functions is studied; the optimal values are determined of the weight coefficients that provide solvability of the inverse problem as well as the limit level of error in the input data of various types is estimated
