In this study, selection of appropriate profile material and a profile section by using finite elements
method during the design studies of the mine roadway support having a cross-section of 5,75
m2 was aimed. The support type was trapezoidal sectioned rigid steel support. In parallel with
the aim of this study, load-profile section optimization studies were carried out by changing the
profile material and profile section while the cross-sectional area of the gallery is kept constant
with considering the load acting on the subsurface mine openings. It was determined that using
of TH29 profile with 31Mn4 material was safer than NPI200 profile with S235 material, according
to the displacement and stress distribution for the subsurface mine openings and the support
spacing can be increased from 1500 mm to 2000 mm as a result, the installation costs could be
reduced by using TH29 section profile.
