Numerical simulation of geomechanical state of coal massif in the vicinity of underground workings in the superimposed seams

The results of numerical modeling of stresses distribution in the formation of coal seams, mined successively in a descending order are presented. The variant is considered, in which the working of the upper seam is carried out in advance and the selvages of the mine workings in the tapped and overw...
