Abstract
The method for estimating deformation characteristics of carrying elements of the room-and-pillar system of solid mineral underground mining and horizontal components of the natural stress field is considered The method is based on solving inverse problems of mixed type within the framework of two-dimensional elastic medium model. The required amount of measurement data, ensuring the unique solution of the inverse problem is obtained by numerical calculations performed for a typical configuration of the goaf, using synthetic input data (relative displacements of the goaf contour points, registered by underground geodesy methods).
