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.
According to the results of geomechanical monitoring in the excavations of Yakovlevski mine distribution of zone water conducting fractures in consequence of displacement and deformation of rocks from concrete backfilling voids evaluated. The convergence of the boundary curvature and the curvature obtained from observations of strata movement to a single span istaken into consideration.

Studies of the processes of displacement of rock massif layers in the course of their initial underworking indicate that their maximum curvature tends to decrease in the inverse proportion to squared distance to coal bed from the layer in question. It manifests itself in the distribution of vertical extension deformations: these are the largest in the vicinity of the coal bed and decrease towards the surface. Such is the consequence of the mechanism of bending the massive layers: the curvature of underlying layers is higher than that of overlying ones. In the zone of complete underworking the maximum curvature of each layer of the repeatedly underworked bedded formation is equal to the maximum curvature of the surface, that is the curvature of the overlying layer repeats the curvature of the underlying one. Hence, the maximum curvature of any layer in the massive is inversely proportional to squared depth of the coal bed suite. Note that the distribution of vertical deformations of the massive differs in both its quality and quantity from that of the initially underworked massive: vertical deformations are an order of magnitude fewer and their distribution is presented by alternating deformations of extension and compression. Such is the consequence of the mechanism of layer bending in case the massive is underworked repeatedly and it explains why the height of the zone of water conducting fractures does not grow in such conditions with respect to the one formed during the excavation of the initial layer of the suite. The technique of forecasting the development of zone of water conducting fractures developed on the basis of such geomechanical processes makes possible safe excavation of coal beds under aquifers.
