    The total load-bearing capacity of steel arch yielding roadways supports is among their most important
    characteristics. These values can be obtained in two ways: experimental measurements in a specialized
    laboratory or computer modelling by FEM. Experimental measurements are significantly more expensive
    and more time-consuming. However, for proper tuning, a computer model is very valuable and can provide
    the necessary verification by experiment. In the cooperating workplaces of GIG Katowice, VSB-Technical
    University of Ostrava and the Institute of Geonics ASCR this verification was successful. The present
    article discusses the conditions and results of this verification for static problems. The output is a tuned
    computer model, which may be used for other calculations to obtain the load-bearing capacity of other
    types of steel arch supports. Changes in other parameters such as the material properties of steel, size
    torques, friction coefficient values etc. can be determined relatively quickly by changing the properties
    of the investigated steel arch supports.
