The present work investigated the mechanical behavior of the fiber reinforced shotcrete applied at the Cuiabá mine excavation and its quality control through the double punch test. For this research, the mix composition was developed by Cuiabá mine Engineers with the addition of two different types of synthetic fibers and one steel fiber. Firstly, the cement based composite was studied at the material level through bending (EN 14651) and pullout tests. Thereafter, the support system of the Cuiabá mine excavation was designed based on round (ASTM C1550), square (EN 14488-5) and large scale panel tests. The application of lower synthetic fiber volume fractions was more suited for the areas with good quality rock indexes, while steel fibers were better suited at field with lower rock classes. Regarding the quality control of FRC, the double punch tests that were conducted in stiffer testing machines were more effective in reducing the post-peak instability, in limiting the errors in the correlations with bending tests (EN 14651) and in reducing the mechanical properties variations of the material. Finally, the application of the double punch test with closed-loop control of the circumferential extensometer turned to be the most effective method in limiting the post-peak instability regardless of the selected machine.
