Tabas coal mine is located south east of Tabas city, in Iran. The mine is the first fully mechanized coalmine in Iran that produces 4000 tonnes coal per day. Method of extraction is retreat longwall. One of the main problems in this mine, is the stabilization of entry roadways. In this research, five different methods were used to calculate potential rock loading on roadways, and according to the predicted rock load two types of section arches; V29 and V36, were considered for stabilization. Finally, the designed support system was numerically evaluated. From the numerical analyses, it was concluded that the roadway East1 Maingate could reach to the stabilised using V29 section arch.
