Abstract
Survey of 12 typical joints with different types of fastenings was carried out. The actual geometric dimensions of the interfaces and fastening space were measured, the zone of rock squeezing at the sides of the excavation was determined, the operational condition and deformation values of the fastening elements in the area of the excavation interface were assessed.
