The results of the convergence researching in the longwall, that were obtained applying three-dimensional computer model of the stratified transversely isotropic rock mass, are presented in the article. The wallrocks convergence curve along a longwall depending on stope attitude along an extraction pillar allows to assess a reserve of hydrocylinder deformation capacity and to predict incidents in the longwalls caused by fitting of powered support onto rigid base. Parameters and results of the three-dimensional simulation of the rock mass are valid for Western Donbas conditions.
