 Summary:
 This paper presents the possibility of using synthetic (polyolefin) and steel fibers in shotcrete to be used in tunnels in the production of primary coatings. In the experimental work, shotcrete slabs with and without the content of polyolefin and steel fibers, as well as slabs with constructive reinforcing mesh were made. Shotcrete slabs were tested for punching (absorption energy). Based on the results of the test it is assumed that it is possible to apply the fibers in the shotcrete during the production of the primary tunnel liner. The obtained values of the shotcrete test with the content of polyolefin fibers, have met the favorable mechanical properties.
