Abstarct: Mining method of room and pillar is an unsupported mining method. In this method, in order to provide roof support, a part of ore is left as pillar. In order to increase the efficiency of this method, entire or a part of pillars can be recovered. Recovery methods are divided into three groups namely, traditional, modern and compound. Among these methods, because of high capability in mechanization and use the mobile roof support systems (MRS), modern methods are more accepted. Nowadays, numerical methods are widely developed for designing and modeling recovery processes according to the limitations of these methods. This research aims at method selection for pillar recovery in room and pillar stops of Parvadeh coal mine of Tabas, regarding the mining sequence by numerical modeling using the FLAC3D. Among the existing methods, two methods of “Modified split and fender” and “Shortwall” were chosen baxsed on the results, recovery percentages for two methods of “Modified split and fender” and “Short wall” were stated 70% and 82% respectively. Finally, with analysis and comparison of two methods, it was concluded that“Shortwall” method is more suitable in this mine.
