One of the most important problems that occurs in rock underground excavations is the rocky massif instability, what entails to rock falling, consequently this could occasion human and material loses; that’s why is vital giving a support to the surrounding rock in order to control opportunely labors and minimizing risks. This study has permitted evaluate the rocky massif physic-mechanic behavior of Colquirrumi miner unity of the Galería Nv. 9, having as basis the geo-mechanic characterization, for getting later the efficient sustenance proposal and apply it to this labor. To fulfill with the proposed objective, the present study was carried out with the following methodologies: • Aplication of geomechanic clasifications: RMR, Index Q and Index GSI. • Estructural analysis using Dips and Unwedge aplication softwares. • Plastic zone determination through the Protodyakonov method and the Phase 2 software use. • Punctual and systematic sustenance modelment using Phase2 and Unwedge softwares. The area was divided in 5 stations, each one of 90 meters approximately, in which were applied the mentioned methodologies, this way were gotten two rock qualities: regular in the 2,4 and 5 stations and good in the 1 and 3 stations. It was proposed punctual and shotcrete bolting in the 2 and 5 stations, in addition of systematic bolting in the 1,3, and 4 stations.
