ABSTRACT
The analysis of the stress-strain state of the mounting system was made. There were detected the regularities of the stress redistribution in the frame and anchor fastening while changing distance of the working face to the roadway. The areas of stress concentration, dangerous for the loss of stability of the elements of the fastening system are defined.
