MINERÍA la mejor puerta de acceso al sector minero EDICIÓN 571 / ABRIL 2025 18 Seguridad Abstract The main infrastructure tunnels of the Andes Norte Project, Nuevo Nivel Mina, of the El Teniente Division, Codelco-Chile, are located in a geologically and geomechanically complex environment. The structural geological condition and the surrounding stress field play a significant role in the excavation-induced seismicity. This has led to the proposal and implementation of a methodology to analyze the causes of rockbursts in deep tunnels. Rockburst (RB) is one of the critical risks that has had to be managed during the construction of tunnels for the Andes Norte Project, as these are associated with the occurrence of excavation-induced seismicity. The consequences observed from the occurrence of this phenomenon can be extremely severe, METODOLOGÍA PROPUESTA PARA ANALIZAR LA CAUSALIDAD DE ESTALLIDOS DE ROCAS EN TÚNELES PROFUNDOS BASADA EN LA EXPERIENCIA DEL NUEVO NIVEL MINA CODELCO, DIVISIÓN EL TENIENTE
