【 摘 要 】

The results of a numerical study of rock deformation near the preparatory mine working during underground mining of coal seams of a complex structure are presented. The evaluation of the stress-strain state of rocks with the location of rock interlayer within the coal seam is performed: in its upper, middle and lower parts.
