Abstract
On the basis of the identity of qualitative distribution of curvature and horizontal deformations the boundary horizontal deformation value is found to assess the water conducting fracture zones height through the deformation parameter. Due to the characteristics of the process of strata movement in geological conditions of Yakovlevski rich iron ore deposit, the values of the boundary horizontal deformation and fracture zone height were found.
