For these mining and geological conditions, recommendations have been developed on the schemes and technology of anchor fastening, taking into account the actual mining and geological conditions for conducting and fastening, and the presence of influencing technological factors. Scientific and technical assistance was provided in organizing monitoring and mastering the technical and technological aspects of conducting and fixing tunnels with anchor systems. A geomechanical survey of the tunnels of the Dnieper metro at the experimental sites was carried out. The results of the implementation - the applied schemes and recommendations for temporary lining are aimed at maintaining the tunnels of the Dnieper metro at the experimental sites in a stable and safe condition for the period before the construction of a permanent lining. This makes it possible to obtain significant economic benefits by reducing maintenance costs and increasing the speed of tunneling using the new Austrian method.
