In the execution of slopes for roads, tunnels and mining works occur occasionally the fall of rocks, which represent a hazard for the safety of people as well as the structures that are around them. In view of this, one of the surface stabilization solutions is the anchoring system consisting of the installation of bolts for rock and galvanized mesh. To determine if the installation was correct, the pull-out test is carried out on the anchors in the field, which are used for the final validation of the installed anchor, previously evaluated in general stability, using programs from the Rocscience house. The present work seeks to provide clear concepts about a Pull Out test to the anchors, whose validation is not only limited to the reading shown on the manometer, but to evaluate the displacement that occurs in the anchor. With the update of the technology new concepts and norms arise in the anchor test theory as found in the ASTM 4435 standard modified in 2013. The project "Installation of the slope support system adjacent to the conveyor belt CV013 and CV023", consists on the permanent installation of a protection system against falling rocks where rock bolts consisting of steel bars of Ø32 mm x 3 m in length were placed, with a yield strength in tension fy = 5200 Kg / cm2, in addition to a mesh HR 30 of 8 x 10cm opening; these were evaluated under the programs Roc Fall V6.0 (evaluate the fall of rock), Roc Data V6.0 (evaluate the strength of the rock), Slide V6.0 (evaluate the stability of the slope) and Dips V6.0 (evaluate present failures), 1% of these anchors were subjected to a Pull Out test using ASTM 4435 as technical information. The contribution of the thesis lies in giving recommendations on the installation of anchors and the Pull Out Test, performing of these tests we corroborate that the quality control in the installation was adequate during the execution of the project.
