The results of numerical modeling of a fracture system spatial development on a coal-rock massif under the hydrodynamic impact are presented. To set boundary conditions, an array of geophysical data obtained with a seismic survey method for the extraction panel roof was used. The parameters of typical geophones placement schemes in mine workings, sufficient for assessing the efficiency of directional hydraulic fracturing are substantiated. Satisfactory convergence of the results of numerical modeling of fracture systems spatial development with areas possessing different physical and mechanical properties revealed during seismic survey of the extraction panel impacted by hydraulic fracturing are presented.
