This study was supported by TUBITAK (116M698) and TKI. Six separate pilot application and monitoring zones are planned in an area of 145 meters in the middle of the material gallery. A pilot application was carried out with different rock bolts in four areas of 25 meters each. In the other two regions, the existing steel arches used in the mine were used. In addition, measurement stations for performance analyses have been established in these regions. In this paper, only the measurement results of steel arches (DMRB) and friction (swellex) rock bolt (SWLX) support systems prepared in the pilot application area will be presented. It has been determined that friction rock bolts (SWLX) reduce the deformations in the gateroad roof by approximately 58% compared to the steel arch (DMRB) support system and make the gateroad safer. © 2023 IMCET 2023 - Proceedings of the 28th International Mining Congress and Exhibition of Turkey.
