The results of the stress researching in the longwall, that were obtained applying three-dimensional incremental computer model of the stratified transversely isotropic rock mass, are presented in the article. The stress curve along a longwall depending on stope attitude along an extraction pillar allows to assess the coal seam’s stress and strain state ahead a stope. Parameters and results of the three-dimensional simulation of the rock mass are valid for Western Donbas conditions.
