Abstract

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