This scientific work is devoted to the study of geomechanical effects during the construction, maintenance and repair of mine workings in coal mines of the Karaganda basin. The study established that the manifestation of deformations in workings when using a combined anchor-frame support is 4-5 times less than when using metal frame support, and the limited-yield anchor support acts as a stress compensator. The revealed patterns of changes in the stress-strain state of coal in the host rock masses depending on mining and geological factors, which will allow, under specific operating conditions, to establish rational parameters for securing side rocks to increase the stability of development mine workings.
