Abstract

This Bachelor thesis deals with the issue of tunneling in the Scandinavian conditions and focuses on boring with using Norwigian Tunneling Method. In the process of this method isused blasting for rock breaking. The main characteristics of of this method are described in this thesis. There are also pointed out the problems that may arise in the implementation of the drilling-blasting work during the conditions in the Nordic countries. The work also includes various aspects that affect the desing of blasting works and the possibillity of solutions. The practical part of this thesis deals with the specified road tunnel profile. For stated section of the tunnel is designed the breaking and explosives type tha twill be used. The proposition includes a calculation of blasting parameters and breaking parameters as well.
