| Abstract |
A model of the geomechanical state of a coal-rock mass, containing in-seam working is
developed for reliable estimation of the geomechanical state of a coal seam, containing a layer with
lower strength characteristics compared to those of the seam. It is based on the fundamental principles
and approaches of deformable solid mechanics and is implemented by the method of boundary integral equations. A computational experiment is performed in the model for a number of mining and
geological conditions of the coal deposit. Based on the analysis of the results, several features in the
stress distribution in the marginal zone of the seam are identified. |
