Peru, with its extensive mining activity, faces unique geological challenges that require specialized engineering solutions. Support structures in subway mines, which often use reinforced concrete, are vital to the safety and efficiency of these operations. In this research, metallic fibers were used to reinforce shotcrete, which were subjected to experimental compression, flexural and shear tests to obtain their mechanical performance. First, a granulometric analysis of the aggregates was carried out. Secondly, 7 types of concrete were designed: the standard design, 3 designs with SikaFiber LHO 45/35 NB (20, 35 and 50 kg of addition) and 3 designs with SikaFiber CHO 65/35 (20, 35 and 50 kg of addition), the proportions were determined according to the technical specifications of each metallic fiber. Thirdly, specimens were prepared for the experimental compression tests at 7 and 28 days, flexural tests at 28 days and shear tests at 28 days. Finally, the results obtained were analyzed, compared and validated with other investigations.
