【 摘 要 】

The results of the evaluation of the stressed state of the rock massif and mine support of the Skipova trunk in the 200-400 m are presented by the modeling method, as well as the bearing capacity of the combined mine shaft support. Investigations of the corrosion intensity of the surface of the metal net of the "Skipova" trunk were performed.
