Abstract
While maintaining workings during operation, work is carried out to eliminate the effects of heaving of soil rocks that occur during plastic deformations with extrusion of soil rocks into the cavity
The revealed patterns of changes in the stress-strain state of coal-rock massifs (displacements, stresses, cracking zones), depending on the main mining-geological and mining-technical factors, made it possible to establish the optimal parameters for fixing soil rocks and developing technological schemes for fixing that can significantly reduce the manifestations of heaving of soil rocks in mine workings . Developed and tested in the mines of the Karaganda coal basin, the technology of anchor fastening of near-contour rocks during mining.
