Sažetak
The paper analyses the costs in connection to the applied mode of blasting in the course of the excavation of the Grič Tunnel. The adjustment of blasting parameters has been done in accordance with dynamic of the works, the cost efficiency of undertaken blasting taking into consideration the change of the existing geological surroundings alongside the tunnel tube. The success of blasting and the price for the cost of drilling/blasting directly influences at the cycle of excavation of the tunnel that is to follow, by regarding the aspect of timing (dynamic aspect)as well as by influencing the entire investment for the tunnel in the end. Continued monitoring of the tunnel conditions as well as harmonization of blasting factors ensures optimal progress of the excavation with minimum price per metre of progress in the tunnel.
