The production of Mine and Tunnel profiles is carried out by the hot rolling method. While the outputs of R&D activities that resulted in successful production techniques and technology are used, processes that provide improvement in the mechanical and metallographic properties of TH and K profiles, which are defined as snap bonds used in mining and tunneling, have been designed. Unlike the thermomechanical plastic deformation processes and standard hot rolling processes designed with R&D activities, in this production method, the finish group can be obtained by making fine pearlitic or bainitic depending on the grain refinement and cooling environment, thanks to the deformation temperature and amount.
When the situation of the mine and tunnel profiles at the place of use is examined; After the previous applications in wood, iron profile, stone and soil mixture compositions, the fortification sets specially designed and manufactured according to the underground openings, together with the locked connection equipment (traversal junctions, clamps) of the TH and K profiles developed with the new technology, can slide through (over) each other under certain forces. In Curved Mine and Tunnel fortification sets, TH profiles are most commonly used, although various geometric profile sections have been tried in which the set can slide through each other without deteriorating the quality and sensitivity of the set. In addition to the suitability of these profiles to slide through each other, another advantage is that their strength moments with respect to the x and y axes are very close to each other and they are more resistant to bending stresses. Under these physical and mechanical conditions, sliding supports become more advantageous than rigid support systems, and even thanks to this increase in load carrying capacity, the security level of underground galleries increases.
