The title of the professional proficiency work is: Geomechanical Study of the Andaychagua Vein for its recovery through positive Long Drills through 2D numerical modeling in the Andaychagua mining unit. Through the geomechanical evaluation, the feasibility of recovering high-grade mineral located in the eastern wall of the Andaychagua vein of NV-1000 is sought to be evaluated. Consideration should be given to recovering part of a vein that is located adjacent to the old vein exploited by the Under Cut and Fill method. According to the geomechanical evaluation, the recovery of the vein is established using long positive drills, constructing a single lower level of drilling, blasting and mineral extraction similar to the opening of a cut in the Long Hole method. For this purpose, the Geomechanical Study of the Andaychagua vein was carried out, where logging information, geomechanical mapping and laboratory tests were used to define the resistance properties of the rock mass and establish the geotechnical units. The study also included analysis to define the design parameters of the mining method and the required support system. With this information, a two-dimensional numerical model was built to recreate the stress-strain conditions that will occur during the exploitation stage. The main objective was to define the optimal exploitation method that ensures the stability of the work and pits, the maximum recovery and the least possible dilution.
