Abstract
The problems of roadway construction and support in unstable rocks are discussed. The stress-strain state of the rock mass and support was modeled when filling inrush in the roof and sides of the mine with phenol resins. The results of calculations when increasing the height of inrush zone in the mine roof are discussed.
