Determining of the parameters of water conducting fracture zone through values of underminen strata horizontal deformations values

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.
