The problem of finding the stress-strain state of the mine support and surrounding rocks when filling the voids with phenolic resins has been formulated and its mathematical modeling has been carried out. The pattern of distribution of stress fields in mine support and rock mass and their change depending on the geometric dimensions of the area filled with phenolic resins have been determined under various boundary conditions. It is shown that the use of phenol resins contributes to an increase in mine support stability, which allows using the developed technology for the elimination of rock caving in different mining and geological conditions. The calculation results have been discussed.
