Estudio y determinación del tipo de sostenimiento para la estabilidad del túnel de la ventana auxiliar que comunica el tunel de descarga con casa de máquinas, mediante la aplicación de métodos de valoración geomecánica de macizos rocosos proyecto hidroeléctrico Mina San Francisco - cantón Pucará - provincia del Azuay.

The need for faster access to the top of the Cavern Powerhouse for lost time due to technical backwardness of the work a first constructive access tunnel auxiliary window which allows the construction progress of the work was raised San Francisco hydroelectric project. Objective aims to develop a study and determine the appropriate maintenance during the stage of excavation, by applying methods of geomechanical assessment of rock mass, which allows to improve the security, viability and economics in the work of tunneling, Hydroelectric Project Minas fan Francisco - Canton Pucara - Province of Azuay. The literature evaluation research to determine the various technical methods, with the documentary information collected for comparison between theory and practice and field visits to observe the operational management during the construction stage of excavation. Geomecánicamente with the results of the Classification of Barton, Lien and Lunde Index (Q), ranking Bieniawski (RMR System) and Classification Hoek and Brown (GSI), a type of support for auxiliary tunnel was determined, calling the rock mass very good quality taking into account the structural mechanic along the route of the tunnel, project implementation improved the quality of life of the populations in the catchment area characteristics, improved services and created new job opportunities.
