Abstract
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.
