When maintaining workings during operation, work is carried out to eliminate the consequences of heaving of soil rocks that occurs during plastic deformations with extrusion of soil rocks into the working cavity under the action of contour rock pressure.

The revealed patterns of changes in the stressed-deformed state of carbon-bearing masses (displacements, stresses, cracking zones), depending on the main mining-geological and mining technical factors, made it possible to establish the optimal parameters for fastening soil rocks and develop technological fastening schemes that significantly reduce the occurrence of heaving of soil rocks in mine workings. The technology of anchor fastening of marginal rocks during mine workings on gentle and inclined coal seams was developed and tested in the mines of the Karaganda coal basin.
